Dograh AI
A self-hostable, open-source alternative to Vapi and Retell for building voice AI agents with a visual workflow builder, letting a team bring their own LLM, speech-to-text and text-to-speech providers.
Dograh AI lets a team build production voice agents with a visual workflow builder, test them, and let AI coding assistants help design and edit them through MCP, instead of depending on a closed SaaS voice platform.
Because the source is open, every line can be modified and any LLM, TTS or STT provider can be plugged in; it supports telephony for inbound and outbound calls, including Asterisk ARI. It installs with a Docker Compose script, and collects anonymous usage data by default unless ENABLE_TELEMETRY=false is set before the startup script runs.
