Show HN: Faultline – Open-source AI SRE agent

Hi HN,

We built Faultline at Chatwoot to help our team debug infrastructure incidents faster. It's an AI agent you can ask questions in plain English — it autonomously queries your monitoring tools, cloud infrastructure, and codebase, then comes back with a root cause analysis.

It connects to New Relic, Sentry, AWS, GitHub, and PagerDuty using MCP (Model Context Protocol) servers and native integrations. You ask something like "Why is the API latency high?" and the agent loops through your tools — pulling APM metrics, checking error rates, scanning recent deploys — until it has enough data to give you an answer.

Stack: Rails 8 + Sidekiq backend, Python/FastAPI agent service using OpenAI, Vue 3 frontend, PostgreSQL, Redis. All integrations are configured through the UI, credentials encrypted at rest.

It doesn't replace an SRE — but it does the first pass of pulling data from five different dashboards and correlating timelines, which usually takes 10-15 minutes manually.
