Keep Deepgram's models, skip the phone bridge
Dograh is the self-hostable voice agent platform with an open-source workflow builder. Run Nova-3 or Flux for transcription and Aura-2 voices on your own Deepgram key, inside an open-source platform where phone lines and a visual builder already work.
Add the key, draw the call, connect a number
Add Deepgram to a model configuration
Key listseveral keys on one connection
Dograh picks one key at random each time it connects, which spreads calls across accounts' concurrency limits.
→ Pick the EU or Australia endpoint if you need one
Draw the call instead of coding it
Nodes and pathwaysone step of the call per node
Each node has its own prompt and tools. An AI assistant can also build agents through Dograh's MCP server.
→ Dictionary words reach Deepgram as keyterms
Point a number at the agent
Telephony provideryour carrier, already wired in
Add Twilio, Plivo, Telnyx or another supported carrier and assign a number. There is no bridge service to host.
→ Test on a real phone line, not only the browser
Deepgram for speech, your choice for the rest
Billed by Deepgram on your own key
Transfer works on Twilio, Telnyx, Plivo, Cloudonix and Asterisk ARI
Dograh does not run the Voice Agent API or Flux TTS
What changes when the agent layer is yours
No phone bridge to maintain
Carriers connect out of the box, so no service sits between the call and a WebSocket, and nothing extra to host.
Models billed on their own line
Deepgram bills its models to your account, so the platform cost is a separate number you can compare.
Open source, BSD-2-Clause
The whole platform sits in one public repository, builder and phone providers included.
No per-minute platform fee self-hosted
Servers and phone minutes still cost. Dograh Cloud charges $0.01 a minute for the platform, plus models.

Deepgram alternatives, step by step
Can Dograh use my Deepgram key?+×
Yes. Add it in a model configuration and pick Nova-3 or Flux for speech-to-text and Aura-2 for the voice. Deepgram bills your account.
Does Dograh run Deepgram's Voice Agent API?+×
No. Dograh replaces the agent API and runs Deepgram's speech models inside its own call flow, tools and telephony.
Can I add more than one Deepgram key?+×
Yes. Add several keys to one connection, and Dograh picks one at random each time it connects to Deepgram.
Do I need to write a phone bridge?+×
No. Dograh connects to carriers such as Twilio or Telnyx directly. Add the provider and point a number at an agent.
Does call audio still reach Deepgram?+×
Yes, when Deepgram transcribes. Audio skips AI vendors only with open-weight models on your servers, and the call still goes through your carrier.
What does Dograh add to the Deepgram bill?+×
Self-hosted, no per-minute platform fee. Dograh Cloud charges $0.01 a minute for the platform. Deepgram bills its models separately.
