Extension Metadata

About this extension
View Django performance metrics directly in browser DevTools. Track database queries, response times, and duplicate queries during local development.

Django DevBar helps you:

• Catch N+1 query problems before they hit production
• Spot slow database queries as you build features
• Track duplicate queries that could be optimized
• Monitor response times without leaving DevTools

🔒 No spyware, analytics, or tracking. The optional page toggle runs on all URLs only to hide/show the #django-devbar element when present; DevTools metrics are read from the inspected page's network log while DevTools is open. 100% open source.

⚙️ Requires Django DevBar middleware in your Django app: https://github.com/amureki/django-devbar

…………………………………..

🛠️ What you get:

• Dedicated "Django DevBar" panel in browser DevTools
• Database query count and total execution time
• Application processing time
• Total response time
• Duplicate query detection

All metrics appear automatically as you navigate your Django app.

…………………………………..

🎯 Perfect for Django developers who want performance insights where they already work — right in DevTools.

🛑 No spyware, no tracking, no unnecessary permissions beyond what's needed for the DevTools panel and the optional page toggle.
