DevTools Console Capture

Buffer console errors, warnings, unhandled rejections, and network failures per-tab. Copy a markdown block to paste into an AI chat.

DevTools Console Capture buffers JavaScript errors, warnings, unhandled promise rejections, and failed network requests per browser tab while you work — so you don't have to keep the DevTools console open and screenshot it. When something breaks, click the toolbar icon and hit "Copy for Claude". The extension produces a clean, formatted markdown block — errors grouped and deduplicated, network failures listed by path and status, plus a short tail of recent logs for context — ready to paste into an AI chat for debugging. Everything is handled locally on your device. Nothing is ever sent anywhere. Captured data lives only in your browser's memory, is organised per tab, and is discarded when you close the tab or click "Clear". Data leaves the extension only when you explicitly click the copy button, which places the text on your clipboard for you to paste wherever you choose. Designed for developers and AI-assisted builders who debug by pasting context into tools like Claude. Publisher: Sidecar Tools.
