Dev Toolbelt
4 dev tools in one Chrome popup. JSON, Regex, Base64, Color.
4 dev tools in one Chrome extension popup. JSON formatter with collapsible nodes. Regex tester with live match highlighting. Base64 encoder/decoder. Color converter: HEX, RGB, HSL. Everything runs locally in your browser. No account, no cloud, no tracking. Free tier is fully functional. Pro adds JSON diff, Base64 file support, palette generator, and dark/light themes for $9.99 one-time.
Hey everyone! Maker here. I built this because I kept a JSON formatter tab, a regex101 tab, a Base64 encoder tab, and a color picker tab pinned at all times. This merges them into a single popup that's two clicks away.
Stack: vanilla JS, Chrome Extension Manifest V3, Stripe for Pro checkout. Around 500 lines of JS total. The license verification runs against a lightweight Go API on Railway.
The free version is fully usable — JSON formatting, regex testing, Base64 text encoding, and color conversion all work without paying a cent. Pro is a one-time $9.99 that adds the diff viewer, file support, palette generator, and dark/light themes.
Happy to answer any questions about the extension, the Stripe integration, or the Chrome Web Store submission process (took about 4 days for Google to review).
