Vapi alternative

A self-hosted Vapi alternative
for teams that own their stack

Vapi is a hosted developer platform for building voice agents. VEXYL gives you the same kind of agent, but you can run it on your own servers next to your PBX, or on VEXYL Cloud when you would rather not operate it.

VEXYL Vapi

Choose VEXYL when

  • You already run Asterisk or FreePBX and want AI agents on it without moving your telephony.
  • Healthcare, finance or government data must stay on your servers.
  • You serve Indian-language callers and want Sarvam or a self-hosted STT.
  • Volume is high enough that per-minute platform fees matter.

Choose Vapi when

  • You want a fully managed developer platform and have no PBX or servers of your own.
  • You prefer not to operate any infrastructure, even through a managed partner.

Frequently Asked Questions

Is VEXYL a drop-in replacement for Vapi?

Not a drop-in API clone. VEXYL covers the same job - AI agents on phone calls - with its own gateway, agent builder (LiteBot) and HTTP API. Most teams move by recreating prompts and tools as LiteBot bots and pointing their SIP trunk at the gateway.

Can I self-host VEXYL like an open-source Vapi?

Yes. The gateway and LiteBot run on your servers as a binary or with Docker. The Developer edition is free for up to 4 concurrent calls.

What if I do not want to run servers?

Use VEXYL Cloud. We run the gateway; you point a SIP trunk at us and add the browser widget to your site.
