12 Best Vapi Alternatives in 2026: Ranked and Compared

Quick Summary

Callers leads for teams that want to run inbound and outbound at scale across voice and messaging, without engineering. Retell, Bland, Synthflow, Thoughtly, and Voiceflow suit builders. PolyAI, Cognigy, Sierra, Decagon, and Five9 fit enterprise CX. Anyreach serves agencies that want white-label.

Looking for a Vapi Alternative?

Vapi lets you stand up a voice agent in minutes. The harder work comes after. You choose providers, wire up speech and language models, tune latency, and keep the whole thing running.

Vapi is a developer platform, so your team assembles the stack and owns the upkeep. Plenty of buyers would rather buy the outcome, launch in weeks, and let a CX team run it without leaning on engineering.

Below are 12 tools worth comparing.

Why Listen to Us?

Callers is an omnichannel AI platform for high-volume B2C, running inbound and outbound through one agent across phone, SMS, WhatsApp, email, and chat with shared context. It powers live customer conversations for DoorDash, Einride, and PadSplit.

The platform was built alongside Google Cloud, scaled 30X, and now runs hundreds of thousands of AI conversations a day, with SOC 2, HIPAA, GDPR, CCPA, and PCI DSS in place.

Customers see the results in their own numbers. One customer cut call-center load by 65% and grew outreach tenfold. Another cut outbound handling time by 46%, then expanded its sales team to keep up with the demand it created.

Why Look for Vapi Alternatives?

Vapi is a strong developer platform, and for teams with engineers who want full control, it does its job well. Here are the main reasons teams look for an alternative.

It's a platform to build on, not a product to use

Vapi hands you the building blocks and expects you to assemble the agent. You choose the speech-to-text, the language model, the text-to-speech, and the telephony, then connect them. That flexibility is great for developers and rough on a CX or growth team that just wants working calls. If nobody on your side writes code, Vapi is hard to own day to day.

The costs stack up and get hard to predict

The headline is a $0.05 per minute platform fee, but that's only the base. You also pay separately for speech-to-text, the language model, text-to-speech, and telephony, all passed through at provider rates.

Real all-in cost usually lands around $0.11 to $0.15 per minute, and it swings with the providers you pick. Add-ons like HIPAA ($2,000/mo) and zero data retention ($1,000/mo) sit on top. Budgeting takes work.

Your team owns the maintenance

Because you assembled the stack, you keep it running. Prompt tuning, latency work, provider swaps, and version upkeep all fall on your side. When a provider changes behavior or a model gets deprecated, that's your ticket to handle. For a lean team, the ongoing load adds up fast.

Hands-on support sits behind the top tiers

Vapi's dedicated engineer and account teams come with the Scale plan and enterprise contracts. On the self-serve Build plan, you mostly lean on docs and community help. If you want a named person who knows your setup while you launch, you're paying up for it or going without.

No built-in campaign engine or step-level analytics

Vapi is built around orchestrating calls and agents, so outbound sequences, retries, and pre-call triggers are things you wire up yourself. Reporting works the same way. You get call data, but the step-level funnel analytics that show where a script drops off are yours to build. Teams running real outbound programs feel this gap quickly.

The 12 Best Vapi Alternatives

1. Callers

Callers is an omnichannel AI platform built for high-volume B2C, where the conversation drives revenue or the customer outcome. It runs inbound and outbound through one agent that covers phone, SMS, WhatsApp, email, and chat, so sales, retention, and support conversations all share the same context.

CX teams build and run it without engineering, and it goes live in weeks.

Where Vapi hands you the pieces to build a voice agent, Callers gives you the finished agent and the team to run it. You skip the provider wiring and the stack maintenance, so a CX or growth team owns campaigns directly, with step-level analytics that show what to improve after launch.

Key features

• Omnichannel one brain: one agent across phone, SMS, WhatsApp, email, and chat with shared context, and natural delivery across 26+ languages with real-time mid-call switching

• Workflow Orchestration: multi-step sequences, conditional retries, pre-call triggers, and post-call actioning across inbound and outbound

• No-code Script Builder: drag-and-drop with AI-assisted scripting, owned by operators, not developers

• Step-level analytics: see exactly where a conversation wins or drops off, with AI suggestions to lift success rate

• AI and human routing: routine conversations run on their own, high-stakes ones warm-transfer to your team

• Built-in compliance: SOC 2, HIPAA, GDPR, CCPA, and PCI DSS

Pricing

Transparent and usage-based, billed per minute with one clean rate: no stacked provider fees, no separate speech, model, or telephony pass-throughs. Scoped to your volume, with a dedicated CSM included on every plan.

Pros

• Voice-first with genuine outbound campaign logic that goes beyond inbound deflection

• Live in weeks, with no professional-services contract or forward-deployed engineers

• Operators build and edit agents without developer dependency

• One agent keeps context across every channel

• Proven at scale with DoorDash, Einride, and PadSplit, backed by Google Cloud infrastructure

Cons

• Aimed at high-volume B2C, so very low-volume or purely developer use cases are a looser fit

Best for

High-volume B2C teams that want production omnichannel AI, strong on both inbound and outbound, live in weeks without engineering.

Why choose Callers over Vapi

Vapi gives you the parts to build a voice agent, then bills the speech, model, telephony, and add-on fees separately, so real cost is hard to predict. Callers gives you the working agent plus the campaign logic, analytics, and CSM to run it, on one transparent per-minute rate with no stacked pass-throughs.

The bigger difference is who runs it. With Vapi, engineering owns the stack. With Callers, your CX, growth, or sales team builds and edits campaigns directly, and you're live in weeks with results inside the first pilot.

2. Retell AI

Retell AI is a developer-first voice platform focused on natural, low-latency phone conversations. It sits closest to Vapi in spirit, giving you a provider-based pipeline where you pick your speech and language models per agent. The difference is a friendlier no-code conversation flow on top of the developer tooling.

Key features

• Conversation flow builder: no-code branching with decision trees, plus full API and SDK access

• Per-step model choice: assign a different language model at different nodes, including your own custom endpoint

• Streaming RAG: real-time knowledge base lookups with function calling during the call

• Telephony flexibility: inbound and outbound, BYO numbers over SIP or Retell-provisioned numbers

• Contact-center integrations: HubSpot, Salesforce, Genesys, Five9, Avaya, and Amazon Connect

• QA tooling: post-call analysis and simulation testing, with SOC 2 Type II, HIPAA, and GDPR

Pricing

Pay-as-you-go, with a blended all-in rate of roughly $0.07 to $0.31 per minute depending on your voice, model, and telephony choices. You get $10 in free credits and 20 free concurrent calls to start, and enterprise pricing is custom.

Pros

• Strong voice quality and low latency

• True bring-your-own-model flexibility, including self-hosted options

• No-code flow builder makes it more approachable than raw infrastructure

• Broad CRM and contact-center integrations

• Transparent, published pay-as-you-go rates

Cons

• Stacked per-minute components make total cost harder to predict

• Still developer-leaning for advanced setups

• No PCI compliance claim listed

Best for

Developers who want Vapi-style flexibility with a more usable builder on top.

Why choose Retell AI over Vapi

Retell covers most of what draws people to Vapi, the same provider choice and per-step model control, but wraps it in a no-code conversation flow that a technical operator can navigate. You keep the flexibility and lose some of the assembly work.

Its published pay-as-you-go pricing also makes it easier to estimate spend before you commit, which is a practical win over piecing together Vapi's separate provider bills.

3. Bland AI

Bland AI takes the opposite approach to Vapi's open orchestration. It runs its own models and runtime end to end, so speech, language, and voice all live on one proprietary stack. That trade buys you a flat per-minute rate and tight latency, at the cost of model choice.

Key features

• Conversational Pathways: visual node-based flow builder with typed variables, loops, and global interruption nodes

• Proprietary end-to-end stack: language, speech, and voice run on Bland's own infrastructure

• Scale and residency: up to 1M concurrent calls, with self-hosted, on-prem, and VPC options on Enterprise

• Multilingual: 40+ languages, real-time translation in 23, and mid-call switching

• Flat per-minute rate: one price covers the model, speech, and telephony, no pass-throughs

• Compliance depth: SOC 2 Type II, HIPAA, GDPR, and PCI DSS v4.0

Pricing

A free Start tier runs at $0.14 per minute. Build is $299/mo at $0.12 per minute, Scale is $499/mo at $0.11 per minute, and Enterprise is custom and contracted to volume. Warm human transfer, SSO, and on-prem are Enterprise-only.

Pros

• One flat, predictable per-minute rate

• Strong latency and very high concurrency

• Deep compliance stack, including PCI DSS

• Dedicated infrastructure and data residency options

• Published self-serve pricing

Cons

• No bring-your-own-model choice, since the stack is fixed

• Live human transfer and SSO are gated to Enterprise

• Steeper learning curve for the Pathways builder

Best for

Teams that want predictable pricing and dedicated infrastructure over provider flexibility.

Why choose Bland AI over Vapi

If Vapi's stacked, variable billing is the pain, Bland's single all-in per-minute rate fixes it. You trade the freedom to pick providers for a stack that's tuned to work together and priced as one number.

It also lands compliance that regulated calling operations need, including PCI DSS, without you sourcing and vetting each provider yourself the way a Vapi build requires.

4. Synthflow

Synthflow positions itself as a complete voice AI operating system with a no-code builder and its own telephony network. It aims to cover build, test, launch, and improve in one place, which is a broader promise than Vapi's orchestration layer. It has moved firmly upmarket on pricing.

Key features

• No-code Flow Designer: visual builder with multi-agent subflows, webhooks, and a Claude MCP integration

• Own telephony network: in-house carrier network plus support for purchased numbers, Twilio, and SIP

• Testing and QA: AI sandbox, custom evaluations, auto-QA, and versioning

• Model flexibility: OpenAI, Azure OpenAI via your own keys, Synthflow-optimized models, and Claude via MCP

• 200+ integrations: HubSpot, GoHighLevel, Salesforce, Zapier, Make, and WhatsApp

• Compliance and white-label: SOC 2 Type II, HIPAA, GDPR, PCI DSS, ISO 27001, with Stripe rebilling

Pricing

Synthflow now leads with Enterprise contracts starting around $30,000/yr, customized to volume, concurrency, and telephony. The older self-serve monthly tiers are being retired for new signups, so treat the previously advertised lower plans as legacy.

Pros

• Broad, all-in-one voice OS with strong testing tooling

• Owned telephony plus BYO carrier options

• Good CRM and agency integration breadth

• Solid compliance stack, including PCI DSS and ISO 27001

• White-label with built-in rebilling

Cons

• New pricing effectively starts at a high enterprise floor

• Self-serve entry tiers are being phased out

• Some non-English accuracy depends on choosing the right speech engine

Best for

Teams wanting a full no-code voice OS with built-in telephony and testing.

Why choose Synthflow over Vapi

Synthflow bundles the pieces you'd assemble in Vapi, including telephony, testing, and QA, into one no-code environment. For a team that wants the workflow handled rather than wired together, that's a real time saver.

The catch is cost. Synthflow's shift to enterprise contracts means it competes with Vapi on capability, not on a low entry price, so it fits teams ready for a committed platform rather than a cheap starting point.

5. Thoughtly

Thoughtly focuses on inbound lead conversion, with CRM-driven agents that call, text, and follow up until a lead responds. It's more of a finished product for revenue teams than a developer toolkit, which sets it apart from Vapi's build-it-yourself model.

Key features

• No-code Agent Builder: node-based visual flows plus a "Vibes" assistant to build agents conversationally

• Model choice: GPT, Claude, or Gemini on all tiers, with custom models on Enterprise

• Omnichannel follow-up: voice, SMS and iMessage, WhatsApp, and email in one workflow

• CRM sync: two-way sync with 200+ integrations, keeping outcomes in your system of record

• Multilingual: 34+ languages with auto language detection and switching

• Telephony options: built-in numbers or bring your own Twilio or Telnyx account

Pricing

The Flex plan starts at $500/mo with unlimited voice, SMS, and email, and usage overages billed after. Scale and Enterprise are quote-only, and Thoughtly does not publish a per-minute rate.

Pros

• Product-grade experience aimed at revenue teams

• Flexible model choice across all plans

• Strong omnichannel follow-up tied to the CRM

• Built-in and BYO telephony

• Voice cloning included on every plan

Cons

• Compliance is tier-gated, so regulated use effectively needs Enterprise

• No published per-minute pricing

• No native A/B testing found

Best for

Inbound lead conversion teams that live inside a CRM.

Why choose Thoughtly over Vapi

Thoughtly is closer to a working revenue tool than a platform to build on. If your goal is to catch and convert inbound leads across voice and messaging, it ships that workflow rather than asking you to assemble it.

For teams without engineers, that's the appeal. You configure agents in a visual builder and sync outcomes to your CRM, where a Vapi setup would need custom development to reach the same place.

6. Voiceflow

Voiceflow is the closest philosophical match to Vapi as a build-your-own platform, though it has repositioned toward chat-first CX agents. It's model and channel agnostic, with a strong visual canvas and developer SDK for teams that want to design and ship agents themselves.

Key features

• Agent platform: build one agent and deploy to web chat, phone, and API, with chat and voice both first-class

• Model agnostic: Claude, GPT, Gemini, or your own models, with failover routing and per-playbook overrides

• Strong RAG: scalable vector knowledge base with tunable chunking and a Knowledge Base API

• Visual canvas plus SDK: no-code design mixed with deterministic workflows and guardrails

• Collaboration: roles, comments, versioning, and dev, staging, and prod environments

• 100+ integrations: Salesforce, Zendesk, and Shopify, with structured human handoff

Pricing

Voiceflow's current pricing page is demo-oriented and shows no tier table. Its own docs reference Pro and Business plans starting around $60/mo, with Business bases higher and Enterprise custom, so exact numbers now live behind the app.

Pros

• Genuinely model and channel agnostic

• Excellent knowledge base and RAG tooling

• Strong team collaboration features

• Deterministic workflows plus agentic playbooks in one builder

• Large self-serve community and template marketplace

Cons

• Outbound is API-only, with no campaign or dialer manager

• No public pricing on the current page

• HIPAA is not clearly confirmed for Voiceflow itself

Best for

Product and engineering teams that want to build and own their agents.

Why choose Voiceflow over Vapi

If you like Vapi's build-your-own control but want a more designed authoring experience, Voiceflow delivers that with a mature visual canvas, real collaboration, and best-in-class RAG. It's a better home for teams shipping chat and voice agents together.

Just be clear on the outbound limits. Voiceflow's outbound calling is programmatic only, so high-volume outbound campaigns still need building, much as they would on Vapi.

7. PolyAI

PolyAI is a voice-first enterprise platform built specifically for spoken customer service. It runs a proprietary model tuned for voice and an in-house speech stack, aiming for natural, low-latency inbound calls that resolve issues end to end.

Key features

• Voice-tuned model: a proprietary model built for customer-service conversations across voice and text

• Low latency: sub-300ms on live calls (vendor claim) for natural turn-taking

• In-house speech stack: ASR tuned for accents and noise, paired with blended TTS

• 45 languages: broad language coverage as standard

• Two builder paths: a no-code agent builder plus a developer SDK

• Enterprise compliance: SOC 2, HIPAA, GDPR, and PCI DSS, with warm human handoff

Pricing

PolyAI is custom and usage-based per minute, quoted after a demo. It does not publish rates, so any figure you see elsewhere is a third-party estimate rather than PolyAI's stated price.

Pros

• Purpose-built for voice, with well-regarded call quality

• Strong accent and noise handling

• Broad language coverage

• Enterprise-grade compliance

• Both no-code and developer paths

Cons

• Inbound-first, so outbound is not a headline capability

• Quote-only pricing

• Enterprise focus can be heavy for smaller teams

Best for

Enterprises that need polished inbound voice self-service.

Why choose PolyAI over Vapi

PolyAI is a finished enterprise voice product where Vapi is infrastructure. If your priority is inbound call quality that handles accents and noise well, PolyAI's purpose-built stack gets you there without assembling and tuning providers.

It's the stronger pick when voice quality on complex inbound calls is the whole job, and you'd rather buy that than build it.

8. Cognigy

Cognigy (now part of NiCE) is a mature enterprise platform for agentic customer service with deep contact-center integration. It blends deterministic flows with autonomous agents and connects into the major CCaaS stacks, which makes it a heavyweight option next to Vapi's lighter developer layer.

Key features

• Composite AI: deterministic intent flows plus autonomous agentic reasoning for hybrid control

• Model agnostic: multiple language models with RAG grounding and MCP tool access

• 100+ languages: broad multilingual coverage

• 30+ CCaaS connectors: Genesys, Avaya, Amazon Connect, and NiCE CXone, plus 110+ marketplace tools

• Autonomous and agent-assist: full agents plus an Agent Copilot and Live Agent workspace

• Enterprise scale: Insights analytics, with GDPR, SOC 2, HIPAA, and ISO 27001

Pricing

Cognigy is quote-only. Billing is conversation-based, counted in blocks of user inputs per its docs, but no dollar figures appear on the site, so any circulating numbers are external estimates.

Pros

• Deep contact-center integration

• Both autonomous and agent-assist in one platform

• Very broad language support

• Strong analytics and enterprise scale

• Analyst-recognized and widely deployed

Cons

• Enterprise deployments take longer to stand up

• Quote-only pricing

• Heavier than many teams need

Best for

Large enterprises that need voice AI wired deeply into an existing contact center.

Why choose Cognigy over Vapi

For a large contact center, Cognigy brings prebuilt CCaaS connectors and both autonomous and agent-assist modes that a Vapi build would have to recreate from scratch. It slots into Genesys, Avaya, or Amazon Connect rather than asking you to integrate them yourself.

It's the enterprise-integration option, best when the requirement is depth across an existing stack rather than a quick, lightweight build.

9. Sierra

Sierra is an Agent OS built by a high-profile founding team, with strong natural-language authoring and rigorous voice testing. It leans on outcome-based pricing and a deep compliance stack, positioning itself as a full platform rather than a toolkit.

Key features

• Ghostwriter authoring: an agent-building agent that generates production-ready agents from SOPs, transcripts, or plain English

• Voice testing: Voice Sims stress-test agents with noise and interruptions before launch

• 59 languages: with seamless mid-conversation switching

• Multichannel: chat, SMS, WhatsApp, email, voice, and ChatGPT

• Observability suite: Explorer, Monitors, Experiments, plus an agent data platform

• Deep compliance: SOC 2, ISO 27001, ISO 42001, HIPAA, GDPR, PCI DSS, and FedRAMP

Pricing

Sierra uses outcome-based pricing, where you pay when the agent achieves a defined result. It publishes no dollar amounts, so any per-resolution or annual figure you find is an external estimate.

Pros

• Fast, natural-language agent authoring

• Rigorous pre-launch voice testing

• Strong observability and experimentation tools

• Unusually broad compliance, including FedRAMP

• Outcome-aligned commercial model

Cons

• Quote-only, outcome-based pricing takes modeling to predict

• Positioned as autonomous-first, with no clear agent-assist product

• Its underlying model approach is undisclosed

Best for

Enterprises that want autonomous CX agents with pricing tied to results.

Why choose Sierra over Vapi

Sierra automates the whole authoring and testing loop that you'd handle manually on Vapi, generating agents from your existing material and stress-testing them before they go live. That's a meaningful shortcut for teams without a voice-engineering bench.

Its outcome-based model also shifts risk in a way Vapi's usage billing can't, since you're paying for resolved conversations rather than raw minutes.

10. Decagon

Decagon is an AI concierge platform for autonomous customer support, known for defining agent behavior in plain natural language. It focuses on action-taking agents that complete tasks end to end, with deep read and write access to your business systems.

Key features

• Agent Operating Procedures: define agent behavior in natural language rather than a config language

• Action-taking agents: complete tasks end to end, like rescheduling a delivery and updating the order

• Omnichannel build-once: voice, chat, and email with cross-channel memory

• Bi-directional CRM: read and write with Salesforce, Zendesk, and Stripe

• QA and testing: A/B testing, at-scale simulation, and Watchtower monitoring

• Handoff and outbound: seamless human escalation, outbound reminders, and a dedicated Agent Assist

Pricing

Decagon is quote-only, with two work-based models: per-conversation or per-resolution. It publishes no rates, so any platform fee or per-conversation figure you see is a third-party estimate.

Pros

• Plain-language authoring that's fast to iterate

• Takes real actions in your systems, going beyond answering questions

• Deep, bi-directional CRM integration

• Solid testing and monitoring tooling

• Offers both autonomous agents and Agent Assist

Cons

• Quote-only pricing

• Voice is newer than its chat and email roots

• Only SOC 2 Type II is publicly disclosed

Best for

Digital-native brands that want concierge-grade autonomous support.

Why choose Decagon over Vapi

Decagon ships autonomous agents that take real actions in your systems, the kind of end-to-end resolution you'd have to engineer yourself on Vapi. Its natural-language authoring means a CX team can shape behavior without writing code.

If the goal is resolved outcomes with deep CRM read and write, Decagon delivers that as a product, where Vapi gives you the runtime to build toward it.

11. Five9

Five9 is an established CCaaS provider layering agentic AI onto a full contact-center platform. Its AI Agents bring multi-agent orchestration and strong governance, which suits buyers who want AI inside a complete suite rather than a standalone voice layer.

Key features

• Multi-agent orchestration: an orchestrator plans the path to resolution while sub-agents execute steps

• Human-like voice self-service: low-latency streaming, interruption detection, and noise management

• Natural-language design: define goals in plain language, or pair with deterministic IVA flows

• Governance: custom guardrails, data redaction, and LLM blinding so sensitive data stays protected

• Native CCaaS and handoff: runs on the full Five9 platform with instant context transfer to live agents

• Analytics: OneVUE unified reporting with customizable dashboards

Pricing

Five9 publishes two entry tiers: Digital at $119/seat/mo and Core at $159/seat/mo, both per concurrent user with a 50-seat minimum. Plus, Pro, and Enterprise are quote-only, and usage-based charges may apply.

Pros

• AI built into a mature, full-featured CCaaS

• Strong orchestration for complex, multi-step requests

• Enterprise governance and data protection

• Native human handoff with full context

• Two entry tiers with published prices

Cons

• Per-seat model, best for existing or adjacent Five9 customers

• Higher tiers are quote-only, with a 50-seat floor

• More than teams wanting a lightweight voice layer need

Best for

Contact centers that want agentic AI inside a full CCaaS platform.

Why choose Five9 over Vapi

Five9 gives you AI agents on top of a complete contact center, with routing, governance, and human handoff already built in. A Vapi setup would need all of that assembled and integrated around it.

For an organization standardizing on a CCaaS suite, Five9's per-seat model and native platform make more sense than maintaining a separate voice build.

12. Anyreach

Anyreach is an omnichannel voice AI platform with cross-channel memory and a strong white-label agency model. It answers calls, messages, chats, and emails with an agent that remembers context across channels, and it's aimed partly at agencies reselling under their own brand.

Key features

• Omnichannel with memory: voice, SMS, chat, email, and WhatsApp with persistent cross-channel context

• No-code workflows: visual automation on all tiers, billed per run

• Voicemail detection: a "Beep Detector" the vendor cites at high accuracy for lifting call success

• Integrations: Salesforce, HubSpot, Zendesk, Shopify, Stripe, Zapier, and Calendly

• White-label agency tier: unlimited client accounts for reselling under your brand

• Compliance: SOC 2, HIPAA, and GDPR, with a 99.9% SLA on Enterprise

Pricing

An SMB tier starts at $0/mo plus usage, with AI voice from $0.19 per minute. The Agency tier is $1,250/mo and doubles as the white-label platform fee, while Enterprise is custom.

Pros

• Strong cross-channel memory

• Clear white-label agency model

• Published entry pricing

• Broad CRM and scheduling integrations

• No-code workflow automation

Cons

• Outbound at volume is described as custom-built, not self-serve

• No confirmed bring-your-own-model option or SIP beyond Twilio

• PCI and a full language list are not confirmed

Best for

Agencies that want to resell voice AI under their own brand.

Why choose Anyreach over Vapi

Anyreach hands agencies a white-label product with published entry pricing, where Vapi would mean building and maintaining a platform to resell. The persistent cross-channel memory also comes built in rather than assembled.

For a services business that wants to offer voice AI to clients quickly, Anyreach is a faster route to market than standing up a Vapi build.

Choose the Right Vapi Alternative

The right pick comes down to who runs it and what you're trying to do. Retell and Voiceflow suit developers who still want to build, with Bland a good fit when you want a proprietary stack and one flat rate. Synthflow and Thoughtly work for teams wanting a fuller product, and PolyAI, Cognigy, Sierra, Decagon, and Five9 fit enterprise CX with deep integration or autonomous support. Anyreach is the agency and white-label play.
