Show HN: Toolbit – A unified, privacy-friendly toolbox for developers

I built Toolbit — a fast, ad-free, privacy-respecting developer toolbox that runs entirely in your browser.

It brings together 20+ everyday utilities like: JSON Formatter & Validator Base64 Encoder / Decoder JWT Decoder Markdown Previewer HTML / CSS / JS Minifiers Word Counter, Diff Tool, and more

Everything runs completely on the client side, so no data ever leaves your machine. You can even install it as a PWA for offline access.

Toolbit was born from frustration with random online tools full of ads, trackers, and inconsistent UIs. I wanted a single, clean space that developers could trust and use quickly without losing focus.

Features: All-in-one workspace for common developer tasks 100% local execution (no server calls or telemetry) Light & dark themes Works on any browser and can be installed as a PWA

I’d love feedback on usability, performance, and what tools you think I should add next.
