We spent three weeks testing every major Voiceflow alternative — timing setup, building real agents, testing AI features, and reading through hundreds of G2, Reddit, and Capterra reviews. One member of our team uses Brilo.ai as a paying customer; we note this where relevant.

Here's what we found.

Why Are Teams Leaving Voiceflow?

Voiceflow has been around since 2019 — and its visual builder is genuinely the best in the category. But for teams trying to ship production agents in 2026, the pricing structure and missing pieces drive consistent switching.

The Pro plan looks like $60/month — but it's only $60 if you have one editor. Each additional teammate is $50/month. A 5-person team on Pro pays $260/month, not $60. On Business, that same team pays $350/month. The advertised price is rarely the real one.

The credit cliff stops agents mid-cycle. Voiceflow's monthly credit allotment is a hard ceiling — when you run out, agents stop responding. There's no top-up option. You wait until renewal or upgrade tier mid-cycle.

"Hit our credit limit on a Saturday during a launch. Couldn't buy more, had to wait for the upgrade to process while every chat just timed out." — G2 review, Pro plan user

No native telephony. Voiceflow markets voice agents but doesn't include phone numbers. To put a voice agent on a real number, you provision Twilio or Vonage separately and pay carrier fees on top of your Voiceflow bill. Most users discover this mid-build.

No native live chat handoff. For a tool aimed at support automation, there's no built-in way to pass conversations to a human helpdesk. Teams stitch together Zendesk or Intercom integrations through the Dialog API — work that ships in hours on competing platforms.

Customer support varies by plan. Lower-tier users describe a primarily self-service experience. Capterra reviewers on Enterprise have reported support tickets going unanswered for weeks during critical project launches.

Our Ranking Methodology

TL;DR Comparison Table

1. Brilo.ai — Best for AI Phone Agents Without Vendor Stitching

Best for: SMB and mid-market teams that want an AI voice agent live in minutes — without managing a separate Twilio account, telephony provider, or LLM contract.

We signed up, pasted our website URL so the AI scraped our knowledge base automatically, picked a phone number, and had a live AI agent answering test calls in 7 minutes and 14 seconds. No Twilio account, no carrier configuration, no editor seats to provision.

What stood

Brilo treats voice as the product, not as a feature bolted onto a chatbot designer. We ran 40 test conversations over two weeks — including deliberately tricky multi-step queries with interruptions and accented speakers. Resolution quality was strong on routine requests, and complex issues escalated cleanly with the full call transcript handed off.

Standout features

Native AI voice agent (no Twilio), multilingual support across 30+ languages, auto-trains from your website in under 5 minutes, real-time sentiment analysis, 6,000+ integrations including HubSpot, Salesforce, and Zendesk.

Pricing:

• Free: 10 minutes/month, 1 agent

• Starter: $49/mo — 160 minutes, $0.18/min overage

• Pro: $149/mo — 600 minutes, 3 agents, $0.16/min overage

• Growth: $499/mo — 2,500 minutes, unlimited agents, $0.14/min overage

• Enterprise: Custom (volume discounts at 10,000+ min/month)

Pros

Native telephony — no third-party Twilio bill. Predictable minute-based pricing — no per-editor fees, no credit cliff. Sub-10-minute setup verified with a stopwatch. Unified dashboard for inbound, outbound, and chat.

Cons

Newer platform than Voiceflow (founded 2023) — the integration ecosystem is still expanding. No drag-and-drop visual flow editor of the kind Voiceflow product designers build around — Brilo's setup is conversational, not flowchart-based. Less suited if you only need chat (Botpress is a better fit there).

What's unique: The only platform we tested where you can answer a phone call with an AI agent without ever touching Twilio, Vonage, or any third-party carrier.

Try it free: brilo.ai — free plan, no credit card, AI agent live in under 10 minutes.

2. Retell AI — Best for Developers Building Voice APIs

Best for: Engineering teams that want fine-grained control over speech-to-text, text-to-speech, and LLM choice via a clean developer API.

Our Testing Experience

Setup took 22 minutes and 8 seconds. Most of that was wiring up our own STT, TTS, and LLM provider — Retell deliberately doesn't bundle these, which gives flexibility but means managing four vendor relationships. The platform itself is fast, with sub-1-second latency on most calls.

"Retell's per-minute pricing is honest, but the all-in cost once you add OpenAI + Deepgram + ElevenLabs is closer to $0.15-0.20/min, not the $0.07 on the homepage." — Reddit, r/voiceai

Pricing

From $0.07/min base. All-in with provider stack typically $0.13–$0.20/min. Enterprise discounts down to $0.05/min at scale.

Pros: Fast call latency. Provider flexibility for compliance-sensitive teams. Strong developer documentation.

Cons: Headline price isn't the real all-in cost. UI is rough — it's a developer tool first. Requires technical setup; non-engineers will struggle.

What's unique: The only platform that lets you swap LLM providers mid-deployment without rebuilding your agent. (See our full Retell AI alternatives breakdown.)

3. Vapi — Best for Voice-First Developer Teams

Best for: Engineering teams building outbound voice products where call control, interruption handling, and audio quality need millisecond-level tuning.

Our Testing Experience:

Setup took 35 minutes — the longest of the developer-focused platforms we tested. The trade-off is real control: silence detection thresholds, interruption sensitivity, voice cadence, and fallback logic are all configurable.

For a developer building a sales dialler or appointment booker, this is the deepest toolkit we tested. We ran 30 outbound test calls and the granularity of behaviour control was unmatched.

The documentation assumes prior voice-AI experience. There is no no-code option whatsoever — if your team isn't engineering-led, this isn't the right fit.

Pricing: From $0.05/min base, scaling up by provider choices. Volume discounts via custom contracts.

Pros:

• Deepest call-behaviour control we tested

• Lowest base per-minute price

• Strong outbound calling support

• Active developer community

Cons:

• Steepest learning curve in the list

• No no-code option whatsoever

• Documentation assumes prior voice-AI experience

What's unique: Granular call-behaviour controls (silence thresholds, interruption sensitivity, audio pacing) aren't available on any other platform we tested.

4. Synthflow — Best No-Code Voice with Bundled Pricing

Best for: Non-technical teams that want voice automation without managing multiple providers — and can absorb the new entry point.

Our Testing Experience:

Onboarded in 18 minutes. The drag-and-drop builder is the most polished of the no-code voice platforms — closer to Voiceflow's design experience but with telephony actually included. Sub-500ms latency held up across our tests.

The catch: Synthflow recently removed the $29/month Starter plan, pushing the entry point to $375/month for Pro. That's a significant jump from where the platform sat 18 months ago, and the community sentiment has shifted accordingly.

"Synthflow used to be the budget pick. Now you're paying $375 minimum just to get past the free trial." — G2 review

Pricing: Pro from $375/month. Enterprise custom. All-in rate $0.08/min for voice + LLM + telephony.

Pros:

• True no-code experience for voice

• Bundled per-minute rate simplifies forecasting

• SOC 2, HIPAA, GDPR compliance baked in

• Voice cloning via ElevenLabs

Cons:

• $375/month minimum is a hard barrier for SMBs

• Recent pricing changes have eroded community trust

• Voice cloning quality varies with the underlying ElevenLabs voice

What's unique: The only no-code voice platform where voice, LLM, and telephony are billed as a single all-in per-minute rate.

5. Bland AI — Best for High-Volume Outbound Calling

Best for: Sales and operations teams running thousands of outbound calls per month, where flat per-minute pricing matters more than feature depth.

Our Testing Experience:

Setup took 28 minutes. Bland is laser-focused on outbound — appointment reminders, lead qualification, debt collection, survey calls. We tested it on a 50-call outbound sequence and call quality was solid, though the pacing felt slightly faster than human-natural.

One important caveat: Bland's policies are unusually rigid for the category. No cancellations, no refunds, no free trial beyond limited free minutes. Read the terms carefully before committing.

Pricing: Standard at $0.09/min, capped at 100 calls/day. Enterprise: custom. Custom: white-glove with full features.

Pros:

• Predictable flat-rate pricing

• Strong outbound deliverability

• Genuine 24/7 calling capacity

• Natural-sounding voices with intonation

Cons:

• No cancellations, no refunds — unusually rigid

• 100 calls/day cap on Standard is restrictive

• Inbound use cases are an afterthought

What's unique: The strictest no-refunds policy in the category, paired with the most aggressive outbound calling capacity. (See our full Bland AI alternatives breakdown.)

6. Botpress — Best for Chat-First Developer Agents

Best for: Developer teams building text-based AI agents with multi-channel reach (web, WhatsApp, Slack, Telegram) and complex backend integrations.

Our Testing Experience:

Setup took 14 minutes. Botpress is the strongest text-based alternative to Voiceflow we tested — the visual builder is comparable, but the LLM-agnostic approach (OpenAI, Anthropic, Mistral, custom) is more flexible than Voiceflow's GPT-4/Claude-only model on paid tiers.

The trade-off: Botpress isn't a voice platform. You can route to voice via third-party telephony, but the platform's core is chat. If voice is your primary use case, this is the wrong tool.

Pricing: Free tier available. Team: $495/month for 50,000 messages and 3 bots. Enterprise: custom.

Pros:

• Best LLM flexibility on the market — bring any model

• Visual builder rivals Voiceflow's design experience

• 190+ pre-built integrations

• Active 1M+ deployed bots community

Cons:

• Voice still requires third-party telephony — same problem as Voiceflow

• $495/month Team tier is steep

• Steeper learning curve than no-code platforms

What's unique: The only platform that's fully LLM-agnostic — swap providers without rebuilding your agent.

7. Lindy — Best for Multi-Step Agent Workflows

Best for: Teams that want an AI agent to not just answer the call, but also update the CRM, schedule a follow-up, and write a summary email — all in one workflow.

Our Testing Experience:

Setup took 11 minutes. What separates Lindy is that the agent doesn't stop when the conversation ends. We ran a test where Lindy answered an inbound call, qualified the lead, booked them into our calendar, updated HubSpot, and sent a follow-up email — all in a single triggered chain.

For teams using AI to complete operational loops rather than just to answer questions, this is genuinely a different category of tool.

Pricing: Pro at $49.99/month. Business at $299.99/month. Enterprise custom.

Pros:

• Strongest workflow automation in the category

• 4,000+ app integrations

• Easy visual builder for non-developers

• Multi-agent collaboration baked in

Cons:

• Voice quality is good but not best-in-class

• Multi-agent setup adds complexity for simple use cases

• Newer platform — fewer enterprise references

What's unique: The only platform we tested where the AI meaningfully completes post-call tasks (CRM updates, calendar booking, document processing) inside the same workflow. (See our full Lindy breakdown.)

8. Cognigy — Best for Enterprise Contact Centres

Best for: Large enterprises (500+ agent contact centres) running multi-channel conversational AI across voice, chat, email, and SMS.

Our Testing Experience:

We didn't run a full setup test — Cognigy doesn't allow self-serve sign-up for production accounts. The platform requires a sales call and a typical implementation runs 8–16 weeks. Pricing is custom and starts north of $300K/year for enterprise contracts.

For teams below mid-enterprise, Cognigy is the wrong category. For teams at the right size with budget, the platform is genuinely deep — native integrations into Genesys, Twilio Flex, and Avaya are unmatched on this list.

Pricing: Custom (sales call required). Enterprise contracts typically $300K+/year.

Pros:

• Genuine enterprise-grade depth

• Mature contact centre integrations (Genesys, Twilio Flex, Avaya)

• Strong telco and financial services track record

• SOC 2, ISO 27001, HIPAA compliance

Cons:

• $300K+ entry point disqualifies anyone below mid-enterprise

• 8–16 week implementation is the norm

• Heavy on professional services — Cognigy partner required

What's unique: The deepest contact-centre orchestration on this list, with native integrations into Genesys, Twilio Flex, and Avaya.

9. Rasa — Best for Self-Hosted, Regulated Industries

Best for: Engineering-heavy teams in financial services, healthcare, and government that need conversational AI running entirely in their own environment.

Our Testing Experience:

Rasa is open-source at the core and self-hosted by design. There's no signup-and-go path — deploying Rasa Enterprise typically takes a small engineering team several weeks.

The pay-off: full code-level control over dialogue management, NLU, RAG, and orchestration, with all data staying inside your infrastructure. For regulated industries that can't use cloud-only AI, this is often the only platform that meets compliance requirements.

Pricing: Custom (sales call required). Annual volume-based pricing, typically $50K+/year for production deployments.

Pros:

• Only platform meeting strict data-residency requirements

• Code-level extensibility across every component

• Strong enterprise voice channel integrations (Genesys, Twilio, Jambonz, AudioCodes)

• Patented CALM dialogue manager for production reliability

Cons:

• No visual builder — engineering team required

• 4–8 weeks to first production deployment

• Steepest learning curve in the list

What's unique: The only fully self-hosted, code-first platform here — designed for teams that can't use cloud-only AI for regulatory reasons.

10. Dialogflow CX — Best for Google Cloud–Native Conversational AI

Best for: Enterprise teams already running on Google Cloud who want a visual flow builder for chat and voice agents — backed by Google's NLU and tightly integrated with the rest of the GCP stack.

Our Testing Experience:

Setup took 26 minutes. Dialogflow CX is Google's enterprise conversational AI platform — a direct architectural match to Voiceflow's visual flow approach, but built for production scale rather than prototyping. The state-machine model (pages, flows, transitions) is genuinely powerful for complex multi-turn conversations.

The trade-off is that Dialogflow CX assumes you're already in the Google Cloud ecosystem. Authentication runs through GCP IAM, billing flows through your GCP project, and the tightest integrations are with other Google products (Contact Center AI, BigQuery, Vertex AI). For teams not on GCP, the friction is real.

One important caveat: Dialogflow CX is usage-priced rather than seat-priced. $0.007 per text request and $0.02 per audio minute sound cheap, but a production agent handling 10,000 conversations/month with mixed text and voice can land at $400–$800/month — different math from Voiceflow's editor-seat model, but not necessarily cheaper.

Pricing: $0.007/text request, $0.02/audio minute, $20/agent/month for the visual builder. Vertex AI Agent Builder pricing for advanced features. Free tier: $300 GCP credit + 60 minutes/month.

Pros:

• Visual flow builder with a powerful state-machine model

• Native Google Cloud integration (Contact Center AI, BigQuery, Vertex AI)

• Strong NLU accuracy across 40+ languages

• Pay-per-use pricing avoids per-seat tax for small teams

Cons:

• Requires Google Cloud account and GCP fluency

• Voice still requires Twilio or another carrier — same architectural problem as Voiceflow

• Documentation is dense and assumes developer audience

What's unique: The state-machine approach to dialogue management — Dialogflow CX uses pages and flows that scale to genuinely complex enterprise conversations where Voiceflow's flow charts can become unwieldy.

How to Choose: A Quick Decision Framework

Need inbound phone support without managing Twilio?

Brilo.ai. Native voice means no separate carrier bill, no SIP configuration, live in under 10 minutes.

Building voice APIs as a developer?

Retell AI or Vapi. Both expose deep developer controls; Vapi has more granular call behaviour, Retell has better documentation.

Chat-first agent across web, WhatsApp, Slack?

Botpress. Closest match to Voiceflow's visual builder, with better LLM flexibility.

Need the AI to do more than talk — update CRMs, book calendars?

Lindy. Multi-agent workflows complete the task, not just the conversation.

Regulated industry needing on-prem deployment?

Rasa. The only fully self-hosted option here.

500+ agent contact centre with $300K+ to spend?

Cognigy. Genuine enterprise depth, but expect 8–16 week implementations.

FAQs

What is the best free alternative to Voiceflow?

Brilo.ai's free plan offers 10 minutes/month with a fully functional AI voice agent — the only voice-native free tier on this list. Botpress also has a free tier for chat-first agents. Voiceflow's own free Sandbox is heavily credit-limited (1,000 credits, agents stop after that).

What is the cheapest Voiceflow alternative?

For voice agents, Brilo.ai's Starter plan at $49/month is the cheapest entry with native telephony included. Retell AI starts at $0.07/min but the all-in lands closer to $0.15/min once provider costs are included. Vapi at $0.05/min is cheapest for technical teams managing their own stack.

Why is Voiceflow so expensive for teams?

Voiceflow charges three times: a base plan ($60–$150/month), $50/month per additional editor seat, and credit-based usage that cuts off agents when exhausted. A 5-person Business team pays $350/month before any credit overages, voice telephony, or third-party integration costs. The all-in number is typically 3–4× the advertised plan price.

Does Voiceflow include phone calling in the base plan?

No. Voiceflow does not provide native telephony. To run a voice agent on a real phone number, you need to provision and pay for Twilio or Vonage separately. This is the #1 hidden cost most users discover only mid-build.

What happens when you run out of Voiceflow credits?

Agents stop responding immediately. Voiceflow doesn't offer credit top-ups — your only options are to wait until your monthly renewal date or upgrade tier mid-cycle. Multiple G2 reviewers report customers hitting "dead bot" responses during traffic spikes.

Is "Voice flow" the same as Voiceflow?

Yes — "Voice flow," "voiceflow," and "Voiceflow AI" all refer to the same conversational AI platform founded in 2019 in Toronto. The official spelling is one word: Voiceflow.

What's the best Voiceflow alternative for AI voice support?

Brilo.ai is the only platform on this list with native telephony, multilingual support across 30+ languages, and sub-10-minute setup. If your primary use case is answering inbound phone calls, you skip Twilio entirely and pay one predictable monthly bill.

Can I migrate my Voiceflow agent to a new platform?

Most platforms (including Brilo.ai) rebuild from your knowledge base rather than import Voiceflow's .vf files directly — typically 1–3 hours of setup work. Botpress has the closest visual model and is the lowest-friction migration target for chat agents.

Is Voiceflow shutting down?

No. Voiceflow remains active and recently won a 2026 G2 Best Software Award. The platform isn't going anywhere — but the pricing structure has pushed many production teams to specialised alternatives over the last 12 months.
