The 9 best Vapi alternatives in 2026
An independent comparison of hosted and open-source, self-hosted voice AI platforms — with real per-minute costs (not just the headline platform fee), free tiers, and telephony notes. No vendor paid for placement.
Compare 9 platforms Read the guideDograh
The closest thing to a self-hosted Vapi: visual workflow builder, telephony, BYOK for LLM/STT/TTS, one Docker command. Free under BSD-2.
Vapi
Still the default managed orchestration layer if you want to swap models freely and ship fast — just budget for the real all-in cost.
ElevenLabs
ElevenAgents (Conversational AI 2.0) pairs the industry's best voices with an agent platform. Calls from $0.10/min.
Comparison matrix: 9 Vapi alternatives
"Realistic cost" is what teams actually pay per minute once speech-to-text, LLM, text-to-speech and telephony are included — not the headline platform fee. Verify current numbers on each vendor's site before committing.

How to choose a Vapi alternative
Four decisions that matter more than the brand name on the pricing page.
1. Self-host vs managed
If you can operate a Docker deployment, open-source options (Dograh, LiveKit Agents, Pipecat) eliminate platform fees and vendor lock-in — your audio and transcripts never leave your infrastructure. Managed platforms (Vapi, Retell) ship faster but meter every minute forever.
2. Compute the true per-minute cost
Headline rates exclude STT, LLM, TTS and telephony. Vapi's "$0.05/min" lands at $0.10–0.30/min in production. Model your real stack, then pilot one week of actual calls before committing — pilots reveal your true number better than any pricing page.
3. Check telephony and concurrency
Confirm whether you bring your own Twilio/SIP or pay the platform's bundled rates, and check concurrency caps — Vapi's pay-as-you-go plan caps at 10 concurrent calls, which can surprise teams mid-campaign.
4. Privacy and compliance
HIPAA / zero-retention is a paid add-on on hosted platforms (Vapi charges ~$1,000/mo). If you handle health, finance or EU data, self-hosting an open-source stack is often cheaper than the compliance tier.
Vapi vs Retell AI: head-to-head
The two most-searched hosted platforms, compared on what teams actually ask about.
| Vapi | Retell AI | |
|---|---|---|
| Pricing model | $0.05/min platform fee + bring-your-own STT/LLM/TTS/telephony at cost | Component billing: voice engine $0.07–0.08/min + LLM + telephony |
| Realistic all-in | $0.10–0.30/min | $0.13–0.31/min |
| Free trial | $10 credit | ~$10 credit (≈60 min), up to 20 concurrent calls on trial |
| Concurrency | 10 concurrent on pay-as-you-go | Scales with plan; enterprise discounts 29–40% |
| Self-host option | No | No (use Dograh, LiveKit or Pipecat if this matters) |
| Best for | Engineering teams who want to swap every component freely | Teams shipping phone agents fast with less assembly |
Frequently asked questions
What is the best open-source Vapi alternative?
For a full platform experience — visual workflow builder, telephony, testing — Dograh is the closest open-source equivalent and self-hosts with one Docker command (BSD-2 license). If you prefer assembling your own stack, LiveKit Agents and Pipecat are the two dominant open-source frameworks; Vapi itself is built on Pipecat.
Is Vapi really $0.05 per minute?
That's only the orchestration platform fee. Speech-to-text, the LLM, text-to-speech and telephony are billed separately by the providers you choose. Community-reported production costs typically land between $0.10 and $0.30 per minute all-in.
Can I fully self-host a voice AI agent?
Yes. Dograh, LiveKit Agents, Pipecat and Vocode can all run on your own infrastructure. You still pay your chosen STT/LLM/TTS providers and a telephony carrier (e.g. Twilio or a SIP trunk), but there is no per-minute platform fee and your call audio stays in your environment.
Which is cheaper, Vapi or Retell AI?
All-in costs overlap heavily ($0.10–0.30/min vs $0.13–0.31/min). The difference is rarely the platform — it's which STT, LLM and TTS models you configure. Run a one-week pilot on both with your real call volume before deciding.
What about Synthflow or Bland AI?
Bland AI targets enterprise-scale outbound (free Start tier at $0.14/min, paid plans from $299/mo). Synthflow is the no-code option for SMBs and agencies, but note it withdrew its cheap self-serve tiers — new customers start on pay-as-you-go or Enterprise contracts from $30k/yr, and sales mainly engages teams doing 20,000+ minutes a month.
