TraceLoad

TraceLoad is a web app (with an optional CLI agent) that runs load tests and automatically ties performance regressions to specific backend traces, database queries, and deploys. Instead of just reporting p95 latency and error rates, it ingests OpenTelemetry traces and logs during a test, then produces a ranked “blame list” of endpoints, services, and queries that caused the slowdown. It also snapshots key infrastructure metrics (CPU, memory, GC, connection pools) and correlates them with traffic patterns. The MVP focuses on making load testing actionable for teams who already have some observability but struggle to connect load-test results to root cause quickly. It won’t replace mature tools like k6/JMeter; it sits on top of them and turns raw results into a short, credible investigation path that engineers can trust.
