Overview
Dograh is an open-source, self-hostable voice-agent platform positioned as the Vapi/Retell alternative for teams that cannot send call audio to a third-party cloud. Licensed BSD-2-Clause and maintained by YC alumni and exit founders, it gives you a drag-and-drop workflow builder where you assemble inbound and outbound voice agents from STT, LLM, and TTS nodes, then deploy with a single Docker command. The pitch is data sovereignty: because the whole stack runs on your own infrastructure, there is no HIPAA, GDPR, or SOC 2 processing obligation on a vendor, and you can read or modify every line. It speaks to Twilio, Vonage, Telnyx, and Asterisk for telephony, supports human handoff with call transfer, and ships an MCP server so coding agents like Claude Code or OpenCode can scaffold and configure voice agents from natural language. A managed cloud and a VPC deployment option exist for teams that want zero ops.
Key Features
- Self-hosted in one command - docker compose up brings up the full stack on your own server; no per-minute platform fee.
- Drag-and-drop workflow builder - Compose voice agents visually from STT, LLM, and TTS nodes without writing orchestration code.
- Bring-your-own models - Plug in Whisper, Kokoro, Voxtral, Qwen, or any OSS STT/TTS you host; no forced vendor.
- Telephony integrations - Built-in Twilio, Vonage, Telnyx, Plivo, Vobiz, Cloudonix, and Asterisk ARI, with human handoff and call transfer.
- MCP server - Let Claude Code, Cursor, or Codex inspect, build, and edit agents from plain-language prompts.
- Data sovereignty - Call audio never leaves your infrastructure, removing third-party compliance review for healthcare, finance, and legal use.
Pricing
| Plan | Price | For |

| Managed Cloud | Usage-based | Fully managed, no ops |
| VPC deployment | Custom | On-prem, founders-operated |
Comparison
vs. Vapi: Vapi is the easier managed API, but it is SaaS-only, proprietary, and charges a per-minute platform fee on top of model costs. Dograh is free to self-host, open source, and keeps audio on your servers. Pick Vapi for fastest launch; pick Dograh when data residency or cost control is non-negotiable.
vs. Retell: Retell offers a polished hosted voice API but no self-hosting path. Dograh matches the core capabilities with an open, forkable stack and no lock-in.
vs. Synthflow: Synthflow is a no-code cloud platform aimed at non-technical teams; Dograh targets engineers who want source-level control and on-prem deployment.
