A small JavaScript library that detects whether browser DevTools is open and its orientation, emitting a 'devtoolschange' event on changes. It works across Chrome, Safari, Firefox, and Opera DevTools, though the README notes it now suffers from false positives.
Use cases
- detect if devtools is open in the browser
- pause canvas rendering when devtools is open
- show debug styles when devtools is open
- get notified when devtools opens or closes
- check devtools orientation in a react app
When to choose
- you need a lightweight, dependency-free browser-side devtools detection with an event-based API
- you want a quick check of devtools open state or orientation in Chrome, Safari, Firefox, or Opera
When to avoid
- you need reliable, false-positive-free detection — the README warns browsers changed and detection is now unreliable
- you need to detect undocked DevTools, which is not supported
- you need server-side or non-browser detection
