After months of building developer tools, I've released 66 free browser extensions for Chrome, Firefox, Edge, and Opera. Every single one is open source, under 50KB, and collects zero user data.
Why I Built These
I kept running into the same problems:
- Extensions tracking my browsing history
- Simple tools hidden behind $5/month subscriptions
- Extensions using 200MB of RAM for basic features
So I decided to build my own. All of them.
The Collection
π§ Debugging
- JSON Formatter - auto-format API responses with syntax highlighting
- Regex Tester - test patterns with live match highlighting
- HTTP Headers - inspect request/response headers
- Console Logger - smart console.log management
π¨ Design
- Color Picker Eyedropper - pick any color from any webpage
- CSS Gradient Generator - visual gradient builder with CSS output
- Font Identifier - identify any font on a page
- Page Ruler - measure pixel dimensions
β‘ Productivity
- Tab Suspender - saves 80% RAM by suspending inactive tabs
- Dark Mode Everywhere - dark mode on ALL websites
- Screenshot Capture - full-page screenshots, no account needed
- Quick Notepad - persistent notes in new tabs
π‘οΈ Privacy & Security
- Cookie Cleaner - one-click cookie management
- Privacy Scanner - check what a site tracks
- Meta Tag Viewer - inspect page metadata
The Numbers
- 66 extensions across 4 browsers
- < 50KB each (most competitors are 2-5MB)
- Zero tracking - no analytics, no user data
- Open source - MIT licensed
What's Next
I'm also building:
- 15 VS Code extensions (available on GitHub)
- Userscripts for popular sites (available on Greasy Fork)
- Digital templates for developers

I'd love feedback - what developer tools are you missing? What would you build if you had the time?
