Dograh: The Open Source Vapi Alternative

Dograh is an open-source, self-hostable voice agent platform and workflow builder. Designed as an alternative to Vapi and Retell, it allows users to fork the stack, plug in their own models, and deploy voice agents anywhere. The platform prioritizes data sovereignty, allowing deployments on-premises or inside a private cloud VPC, ensuring that calls, recordings, transcripts, and customer PII never leave the user's data boundary.

Key Features

• Customizable Stack: Users can plug in their preferred inbound channels, Speech-to-Text (STT) like Whisper or Voxtral, Large Language Models (LLMs), Text-to-Speech (TTS) like Kokoro or Chatterbox, and telephony providers like Twilio.
• Speech-to-Speech (S2S): Supports real-time audio-to-audio processing using models like Gemini 3.1 Flash Live or GPT Realtime, enabling fluid turn-taking, interruption handling, and support for over 70 languages without a transcription cascade.
• Pre-recorded and TTS Mixing: Combines real human voice clips with TTS in the same cloned voice to reduce latency, lower costs by up to 3x, and improve conversion rates.
• Model Context Protocol (MCP): Integrates with IDEs and agent runtimes like Claude Code, OpenClaw, Cursor, and Codex, allowing developers to build, modify, and deploy voice agents directly through code.
• Flexible Deployment Options: Offers three ways to run: a forever-free self-hosted open-source version (BSD 2-Clause), a fully-managed cloud, or a managed private cloud deployed inside the user's VPC.
• Enterprise-Ready Compliance: Built for regulated industries, allowing organizations to maintain existing HIPAA, GDPR, SOC 2, ISO 27001, and CCPA compliance by keeping data fully air-gapped and within their perimeter.

Use Cases

• Customer Support: Automating inbound and outbound customer service calls.
• Financial Services: Conducting EMI reminders and soft-collections for banking and fintech.
• Regulated Industries: Secure voice operations for healthtech, telemedicine, insurance, legal intake, pharma, defense, and government sectors.
