🚀 Get Started

Prerequisites

Before you begin, make sure you have the requirements installed. See 📋 Prerequisites for system requirements and port availability.

The only command you need to run:

Download and setup Dograh on your local machine
curl -o docker-compose.yaml https://raw.githubusercontent.com/dograh-hq/dograh/main/docker-compose.yaml && REGISTRY=ghcr.io/dograh-hq docker compose up

Note


First startup may take 2-3 minutes to download all images. Once running, open http://localhost:3010 to create your first AI voice assistant!
For common issues and solutions, see 🔧 Troubleshooting.

🎙️ Your First Voice Bot

  1. Open Dashboard: Launch http://localhost:3010 on your browser
  2. Choose Call Type: Select Inbound or Outbound calling.
  3. Name Your Bot: Use a short two-word name (e.g., Lead Qualification).
  4. Describe Use Case: In 510 words (e.g., Screen insurance form submissions for purchase intent).
  5. Launch: Your bot is ready! Open the bot and click Web Call to talk to it.
  6. No API Keys Needed: We auto-generate Dograh API keys so you can start immediately. You can switch to your own keys anytime.
  7. Default Access: Includes Dograhs own LLMs, STT, and TTS stack by default.
  8. Bring Your Own Keys: Optionally connect your own API keys for LLMs, STT, TTS, or telephony providers like Twilio.
