What is dograh?
An open-source, self-hostable platform for building production voice agents (inbound and outbound calls) through a visual workflow builder. It positions itself as a self-hosted alternative to Vapi and Retell.
Pros & Cons
Pros

- Telephony integrations (Twilio, Vonage, Telnyx, Cloudonix)
- BSD-2-Clause, permissive and OSI-open
Cons
- Docker setup required; hardware specs are not documented
- Brings no engine of its own - quality depends on your own LLM/STT/TTS keys
- Voice-agent reliability is on you to validate
License
