Faultline – Open-source AI agent for infrastructure debugging
It wires an autonomous agent (Python FastAPI + MCP clients) into real observability tools — Sentry, New Relic, PagerDuty, GitHub, etc. — and runs iterative queries to cross-reference signals and surface a likely root cause. Nice pragmatic architecture (Rails + Vue frontend, Sidekiq workers, separate agent service), but the payoff depends heavily on integration coverage and how well it avoids model hallucinations.
