About Toolzy

Toolzy is 45 browser-based developer tools that do one thing each and do it fast. No accounts, no waiting — you paste something in and get a result.

I built it because every time I needed to decode Base64 or format some JSON, the sites I found were either slow or wanted me to sign up first. This is the version I wanted to exist.

Still adding new ones when I find something I keep needing. If there's a tool you wish existed here, let me know.

Your data doesn't get stored or sent anywhere. We don't see what you paste in, and we don't want to.

Everything on Toolzy is free. No premium tier, no usage limits.
