Monitoring for AI agents in production. Traces every run and tool call, groups repeated failures into one issue, and simulates a change on a pull request before you merge.
Why I recommend it: Free tier available; paid plans start around $150/month. Built for engineering teams shipping customer-facing agents — not something a job seeker will use, but useful if you build with AI.
Observability platform with a free-forever tier for distributed tracing, metrics, OpenTelemetry support and AI-assisted debugging. Useful for engineers learning modern observability and incident response.
