Show HN: Faultline – Open-source AI agent for infrastructure debugging

An open-source AI agent for infrastructure debugging. Ask questions about your infrastructure in plain English — it queries your monitoring tools, cross-references the data, and comes back with a likely root cause.

We built this at Chatwoot to speed up our own incident investigations. Read more at faultline.chatwoot.com.

Here is a video on how it works.

You ask a question. The agent uses MCP (Model Context Protocol) servers and custom tools to query your integrations, iterates through the data autonomously, and returns a complete analysis.

The Docker Compose setup runs 5 containers:

The web service automatically runs db:prepare on startup (creates the database and runs migrations). Check http://localhost:3000 and create an account.

PostgreSQL and Redis data is stored on the host at /var/data/faultline/. This survives container restarts, docker compose down, and even full Docker reinstalls.

See .env.production.example for the full list. Key variables:

Defaults work for local development. Integration API keys (New Relic, Sentry, etc.) are configured through the Settings UI, not environment variables.

All integrations are configured in Settings from the UI. Credentials are encrypted at rest.

All integrations except OpenAI support multiple instances (e.g. multiple AWS accounts).
