Fork every box.
Click any node to see the providers you can plug in. Pick your inbound channel, STT, LLM, TTS, and telephony. Or skip the cascade entirely and switch the whole pipeline to speech-to-speech.
Build by writing.
Dograh ships a Model Context Protocol server. Point Claude Code, OpenClaw, Cursor, or any agent runtime at it: they can spin up, modify, and deploy full voice agents on your stack, without leaving the IDE.
works with: claude code · openclaw · cursor · codex · any MCP client
2x conversion. More humane.
Real human voice clips, mixed with TTS, in the same cloned voice. The LLM picks a pre-recorded line when one fits, and falls back to TTS only when it doesn't. Unprecedented latency gains. Cost down up to 3×. Sounds actually human.
Real-time. Audio-to-audio.
Audio goes in, audio comes out. No transcription cascade, no text round-trip. The same conversation feels fluid, natural, and precise: real turn-taking, real interruption handling, ultra-low latency.
Use Gemini 3.1 Flash Live (or Vertex AI) or GPT Realtime 2
text round-trip · 3 hops · cascade latency

Run the whole stack on your infra.
Full data sovereignty. Lower latency as a bonus. Plug in Voxtral, Kokoro, Whisper, whatever runs in your VPC. One of the most-requested features in the repo, and arguably the reason a lot of teams cannot use a hosted voice-agent vendor at all.
STT and TTS are production-ready. LLM swapping is in beta.
... and any model you can host
Same stack. Where you want it.
Run Dograh yourself on your own servers. Let us run it for you on our managed cloud. Or have us deploy the entire stack inside your VPC and operate it for you.
Run it yourself.
Clone the repo, docker compose up, you're running. Forever free, BSD 2-Clause, your servers, your data.
Let us run it.
Our fully-managed cloud, same stack, zero ops. We host, patch, and scale. You build agents and ship them.
Your VPC, our ops.
We deploy the entire stack inside your cloud. Data stays on-premise. We handle orchestration, upgrades, and reliability.
Built for the regulated world.
Slots inside your existing compliance perimeter. Skip the vendor review dance: no HIPAA review on us, no GDPR sign-off on us, no SOC 2 on us. The code is open, so your security team can audit every line before a single call goes out.

Things worth asking.
Three reasons. (1) Your data never leaves your premises, critical for fintech, healthtech, defense, EU/GDPR. (2) You can read the code, audit it, fork it; no vendor lock-in. (3) No vendor compliance dance: you don't need us to be SOC 2 or HIPAA or GDPR-certified because we don't see your data.
