Dograh is a self-hostable voice agent platform built for teams that can't hand call recordings, transcripts, or customer PII to a third-party vendor. It's the open-source alternative to Vapi and Retell, licensed under BSD-2-Clause, and designed to run entirely within your own infrastructure perimeter.
The core idea is a modular pipeline you assemble yourself. Pick an inbound channel, a speech-to-text provider, an LLM, and a text-to-speech engine. Swap any node for a different provider, or skip the cascade entirely and run a speech-to-speech model like Gemini Flash Live or GPT Realtime for single-hop, audio-in/audio-out conversations. Lower latency, real interruption handling, no text round-trip.
Key capabilities:
For regulated industries like healthtech, fintech, insurance, and government, the pitch is direct: your existing HIPAA, GDPR, and SOC 2 controls keep covering the data because Dograh never sees it. The code is auditable, so your security team can review every line before a call goes out. No vendor compliance review needed. Compared to LiveKit or hosted platforms, Dograh's differentiator is the combination of a visual workflow builder, MCP-driven agent creation, and genuine data sovereignty, all in one stack you can fork and run yourself. Three deployment modes cover the range: self-host on your own servers, use their managed cloud, or have them operate the stack inside your VPC.
Every Sunday we deconstruct one proprietary app and pick the best open source alternatives worth switching to.
