If you’re like me, you probably use a bunch of Chrome extensions every day: from distraction blockers like Distraction Free Reddit or DF Tube, to UX add-ons, testing tools, or AI helpers.

But switching them on/off manually through Chrome’s settings can be tedious — especially if you just need one active for a moment and want it gone the next.

That’s where Extensity comes in.

🎯 A lightweight, no-frills extension manager for Chrome.

With Extensity, you can toggle any extension on or off with a single click — right from the toolbar. No more scrolling through your extensions list or wasting time digging into settings.
