Captures console logs, warnings, and errors in the background — even when DevTools is closed. Console Catcher captures console.log, console.warn, console.error, console.info, and console.debug calls from any webpage you visit — even when DevTools is closed. Open the popup to review captured logs, filter by level, search, and copy or export. Perfect for debugging issues that only appear briefly or for monitoring console output across multiple tabs. HOW IT WORKS: 1. Visit any website 2. Console Catcher silently records every console.* call and unhandled error in the background 3. Open the popup to see what's been captured — color-coded by level, with timestamps and stack traces 4. Click "Run Test" on the empty state to inject sample console calls and verify capture is working WHAT'S NEW IN v1.0.3: Run Test Button — On the empty state, a new "Run Test" button injects four sample console calls (log/warn/error/info) into the current page so you can verify the extension is capturing correctly without needing to find a page that logs something. Restricted Page Warning — When the popup is opened on chrome://, edge://, file://, or about: URLs (where content scripts can't run), a clear message explains why capture isn't available there. Backwards Compatible — All existing captured logs are preserved. The new permissions (activeTab + scripting) are used exclusively by the Run Test button and never run unless you click it. CORE FEATURES: - Captures console.log, warn, error, info, debug calls - Captures unhandled errors and promise rejections - Per-tab log isolation (no cross-tab leakage) - Search and filter by level - Copy single entry or export all to clipboard/JSON - Automatic cleanup when tabs close (no orphaned storage) - 500-entry-per-tab cap to prevent runaway memory - Zero network requests — everything stays in your browser PRIVACY FIRST: - All captured logs live in chrome.storage.local on your device - Logs are deleted when the tab is closed or navigates away - No data is sent to any server - No accounts, no analytics, no tracking - The extension only reads the ARGUMENTS of console.* calls — never page HTML, form data, cookies, or request bodies USE CASES: - Debug bugs that only appear briefly before the page reloads - Monitor a page running in the background for warnings/errors - Capture console output from a page you can't easily attach DevTools to - Verify that a third-party widget is or isn't logging what it claims FREE TO USE: Console Catcher is completely free with no ads or premium tier.
