Inject CSS & JS into any page — no DevTools needed

JustZix is a free Chrome extension that injects custom CSS and JavaScript into any page using URL-pattern rules. It adds in-tab developer windows — a CSS pane, a JS pane, a JS Console (REPL) and a 6-tab Output Console (console logs, network requests, errors and the GTM dataLayer) — so you can edit, debug and customize sites without DevTools. Hide banners, force dark mode, QA a GTM setup, mark DEV/STAGING environments, or build small page tweaks that persist. No account required, no telemetry.

I've been using JustZix for a while now and honestly it just clicks for me, because I can finally drop my own CSS or JS onto any page without messing around with production code. What I love the most is how the rules are organized into catalogs and groups, so even when I'm jumping between projects everything stays within reach and I can quickly toggle things on or off. The built in Console is a total win for me, because I don't have to keep opening DevTools every time I want to check something.
