About IT Toolkit

IT Toolkit is a free collection of browser-based utilities built for IT professionals, developers, and sysadmins. Everything runs entirely in your browser — no accounts, no servers, no data ever leaves your machine.

🔒

Private by design

All tools run client-side. Your passwords, hashes, JWT tokens, and subnet data never touch a server.

⚡

Fast and focused

No sign-up, no adverts, no bloat. Open a tool, use it, move on.

🆓

Free forever

IT Toolkit will always be free to use.
