.NET trace analyzer

Inspect .nettrace files,
in your browser.

Drag a .nettrace file anywhere on this page. Everything runs locally — no upload, no server, no telemetry.

• Reads EventPipe traces from dotnet-trace, EventPipeSession, or PerfView
• Flame graph with method names, per-thread filter, search · sandwich (per-function) view · time chart per thread
• Static site · works on GitHub Pages, file:// won't work (use a local server)
