v1.0.0
Reqpane v1.0.0
Chrome extension for capturing API calls, detecting errors, and exporting debug info.
Highlights
Chrome DevTools Protocol Integration
Migrated from page-context monkey-patching to chrome.debugger CDP for network capture. This fixes compatibility with Cloudflare Turnstile, Akamai Bot Manager, and other anti-bot systems that detect tampered browser APIs.
- Network domain — passive capture of all XHR/Fetch requests with full response bodies
- Fetch domain — request interception for mock responses and breakpoints
