About this app

stupid devtools brings desktop-style debugging to mobile. Invoke the extension popup on any page to capture console logs, errors, and network calls, then review everything in the host app. Run JavaScript, inspect fetch/XHR requests with headers and bodies, and monitor runtime errors and unhandled rejections. Logs are organized by tab and stored securely offline on your device. Alongside the browser extension it also has a companion app to allow easily interacting with the web app and quickly switching to see logs.

What's new

Version 1.1.0 · Nov 2, 2026

Now called stupid devtools, with a new icon and a simpler design. - Long-press a request to copy it as cURL or fetch, or copy its URL or response - Responses are formatted by type (JSON, XML, forms, images), with a Raw toggle - The popup shows only the current tab, and keeps its logs when Safari pauses the extension - Logs are captured from the very start of the page load - Requests no longer lose their responses, and pages load without waiting on devtools - Better console output for objects, errors and printf-style messages
