The Problem
Most Chrome extensions are either bloated, shady, or outright spyware. They demand unnecessary permissions, sneakily collect your data, and then sell it to God-knows-who. Worse, they're closed source, so you can't audit them even if you wanted to. If you're using extensions to manage tabs, dismiss cookie banners, or tweak CSS, you probably have half a dozen sketchy add-ons installed right now. That's a security nightmare waiting to happen.
What This Does
superlevels solves this by cramming 12+ useful features into a single open-source extension you can actually trust. Think of it as the Swiss army knife for Chrome power-users. The repo includes everything you need: darkmode.js toggles site-wide dark mode with customizable brightness. nocookie.js auto-dismisses cookie consent banners like your personal GDPR hitman. unhook.js declutters YouTube so you can actually focus on the video instead of falling into a Shorts rabbit hole. livecss.js is a live CSS editor that lets you write and preview custom styles for any domain.
The magic happens in background.js, which ties these individual tools together into a single extension. Features are modular, so you can tweak or remove anything you don't need. The manifest.json is clean, with only the permissions necessary for the features to work — no suspicious requests for your bookmarks or browsing history.
Real-World Use
Say you’re doing web research for a project. You open 20 tabs, half of them have annoying JavaScript popups, and the other half keep redirecting you through ad trackers. Instead of installing five separate sketchy extensions, you use superlevels to: Auto-close inactive tabs after 5 minutes (background.js). Disable JavaScript on popup-heavy sites (popup.js). Trace redirect chains (xdim.js) to find the real URLs. Apply your custom dark theme (darkmode.js) for late-night browsing.
Bonus: you can audit every line of this code yourself, or let an AI tool confirm there's no data exfiltration nonsense going on.
The Bottom Line
superlevels is like a multi-tool for anyone who spends way too much time in Chrome. It’s not for casual users — if you’ve never heard of a "manifest file" or don’t care about privacy, this probably isn’t for you. But for devs, power users, and anyone tired of sketchy extensions, it’s absolutely worth cloning and customizing. Just don’t forget to star the repo — it’s sitting at zero right now, which is honestly criminal.
