Why this exists
Most developer tool sites bury a genuinely useful utility under intrusive ads, slow load times, and a design that hasn't changed since 2012. DevTools Hub started from a simple frustration: needing to decode a JWT or format some JSON shouldn't mean fighting a cluttered page just to get to the input box.
So this is a single, fast, modern home for the utilities developers reach for constantly — UUID generation, JSON formatting, JWT decoding, hashing, encoding, and more — all under one roof, with a consistent design and no unnecessary friction.
How it works
Nearly every tool here runs entirely in your browser. When you paste a JWT into the decoder or generate a password, that data is processed locally in JavaScript and never transmitted to a server — see the Privacy Policy for the specifics. This isn't just a privacy nicety; it's also what makes the tools fast, since there's no network round-trip involved.
What's next
The catalog is actively growing — the plugin-based architecture behind the site makes it straightforward to add new tools without disrupting existing ones. Longer-term plans include an optional Pro tier (history, favorites, no ads) and a public API for teams that want these utilities in their own backends.
