Overview
Error notifier for your browser: catch console errors and failed requests, then hand them to your AI in one click. No DevTools.
Racna is a quiet Chrome extension that catches what breaks on the pages you build, then hands it to your AI in one click. When something goes wrong, you normally open DevTools and dig through the console while your app reflows into a thumbnail of itself. Racna does that part for you. It sits in the corner and, the moment an error or a failed request happens, drops it into a small overlay with the context around it, so you see what happened without leaving the page. WHAT IT CATCHES • Console errors and warnings • Uncaught exceptions and unhandled promise rejections • Failed network requests (fetch and XHR), with status, headers, request body, and response body THE TRAIL THAT LED TO IT Every entry comes with a breadcrumb timeline of what happened just before: recent navigation, clicks, console logs, and HTTP calls. That context is the difference between a bare stack trace and something you (or your AI) can actually reason about. HAND IT TO YOUR AI IN ONE CLICK One click copies an entry as clean Markdown. Flip on AI format and the same copy becomes a structured document made for your assistant: error first, fenced sections, a breadcrumb timeline, and credential headers masked. Paste it straight into Claude, Cursor, or a teammate's inbox. Select several entries and export them together as a single Markdown file for a bug report. FOR BACKEND WORK TOO No frontend of your own? Racna captures failed calls fired from in-page API consoles like Swagger UI, RapiDoc, and Stoplight Elements, request and response included. Test an endpoint, and any failure is right there, ready to copy. TUNE THE NOISE Watch rules turn the patterns you care about into toast notifications. Ignore rules mute known noise so the panel only counts what matters. Choose what it captures, which corner it sits in, and which sites it runs on. YOUR DATA STAYS YOURS Racna sends no telemetry and makes no network requests of its own. Captured events live in the tab's memory and disappear with it. Your rules and settings are stored in the browser's own sync storage, nowhere else. There is no server behind this extension. ENABLE IT WHERE YOU WORK Racna stays off until you switch it on for a site from the toolbar. Out of the box only localhost and 127.0.0.1 are enabled, so your everyday browsing is untouched. NOT A DEVTOOLS REPLACEMENT When you need deep inspection, DevTools is still the right tool. Racna covers the moments before that: a tab you left running, a colleague's machine, that one page that only misbehaves while the console is closed. Open source. Works in Chrome and Edge.
