01 · Capture

Zero-config request recording

Point Tracewell at any local port. It captures every HTTP request and response without touching your application code.

  • Headers, bodies, and timing data
  • Works with any language or framework
  • Filter by path, method, or status

02 · Replay

Step through requests like code

Replay any request with a single command. Jump forward and back through the timeline to pinpoint exactly when things went wrong.

  • Replay to the same or different endpoint
  • Compare responses across runs
  • Export as cURL or HTTPie
