  DevTools++ is a lightweight web and API analysis tool built directly into Chrome DevTools. No separate proxy. No context switching. Just open DevTools and start working.
  
  KEY FEATURES
  - Monitor — live request capture with automatic security-pattern Detection
  - JS Trace — timeline of how page JavaScript handles auth, sessions, and tokens
  - JS Context — correlates each request with the JS calls around it (Monitor ↔ JS Trace bridge)
  - Replay & Tamper — edit any captured request and resend, with response diff
  - Intercept (Proxy Mode) — pause and modify requests/responses both ways
  - Auto Decode — inline JWT / Base64 / URL-encoded / nested JSON
  - Initiator — request call stack with source-map decoding
  
  Note: Intercept requires a free local helper installed separately (one-time setup; instructions included in the extension). All other features work with no setup. No data is collected — everything runs locally on your machine.
