Dograh

The open-source, self-hosted alternative to Vapi and Retell

Visit Dograh

What it is

Dograh is an open-source, self-hostable voice AI agent platform built as a drop-in alternative to Vapi and Retell. You can self-host the full platform for free under a permissive BSD-2 license with no artificial limits, bring your own LLM, STT, and TTS models or use speech-to-speech directly, and build call flows with a visual drag-and-drop workflow builder. A managed cloud option also exists for teams that don't want to run their own infrastructure, billed at 1 cent per minute.

What you get free vs paid

Verdict

Where it wins and loses

Pros

  • Self-hosted version is genuinely free forever under BSD-2, not a crippled community edition
  • 4.2k GitHub stars and 856 forks, real open-source traction for a young project
  • Built-in telephony integrations (Twilio, Vonage, Vobiz, Cloudonix) instead of wiring that up yourself
  • Bring-your-own-model flexibility across LLM, STT, TTS, or full speech-to-speech
  • Zero-config start with auto-generated API keys, working voice bot in under 2 minutes per the docs

Cons

  • Self-hosting still means you own the Docker, scaling, and uptime work that a fully managed plan takes off your plate
  • Managed cloud pricing (1 cent/min) has no published free allowance beyond self-hosting it yourself
  • BSD-2 license is permissive, but the plugin and integration ecosystem is smaller than Vapi's or Retell's
  • Enterprise features like SSO/SAML and data residency are custom-priced only, nothing published

The clear pick if you want to own your voice AI stack and your call data instead of renting it, as long as you're comfortable running Docker infrastructure yourself; if you want zero ops, the managed cloud plan or a hosted competitor is still simpler.
