Dograh

Dograh is an open-source voice AI platform for creating production voice agents. Its visual workflow builder supports start and agent nodes, instructions, tools, transitions, end-call outcomes, knowledge bases, webhooks, tool calling, QA, browser audio testing, and text-based test conversations.

The platform connects telephony providers including Twilio, Vonage, Telnyx, Plivo, Vobiz, Cloudonix, and Asterisk ARI. Users can bring their own LLM, TTS, STT, and telephony providers, use MCP clients to inspect or edit agent workflows, and create agents or outbound calls with Python and Node SDKs.

Dograh can run locally or on a remote server using Docker, with bundled MinIO or S3-compatible storage. A managed cloud version is also offered, while the repository documents self-hosted deployment and a BSD 2-Clause license.
