Developers Finally Got an Open-Source Voice AI Platform (Dograh)

Dogra (also referred to as Dogora) is a newly released open-source, self-hostable voice AI platform positioned as an alternative to hosted services like Vapi, Bland, and Retell. It combines a visual workflow builder, a voice engine that connects phone providers, STT, LLM, and TTS, and a platform layer with tracing, recordings, and analytics. Developers can bring their own LLM and TTS providers, inspect the source code, and avoid vendor lock-in and layered platform fees. A demo walkthrough shows building a lead qualification agent with prompt nodes, API tool calls, branching, and call transfers — all without custom orchestration code.
