About

Inject JavaScript

Inject JavaScript adds a smart sidebar to your browser that lets you run custom JavaScript on web pages instantly.

Instead of opening Developer Tools, copying code, or repeating the same steps across pages, Inject JavaScript allows you to inject JavaScript with a single click. Scripts appear only when the current page matches your rules, keeping the interface clean and relevant.

Why install Inject JavaScript?
	•	Run JavaScript instantly
Inject custom scripts into the current page with one click.
	•	Context-aware actions
Scripts only appear on pages where they apply, based on URL and page content.
	•	No DevTools required
Faster and more convenient than pasting code into the console.
	•	Flexible and customizable
Control when scripts appear and what they run.
	•	Local and private
All scripts run locally in your browser. No accounts. No tracking.

Inject JavaScript is ideal for developers, testers, learners, and power users who want more control over how web pages behave — quickly, safely, and on demand.
