Free Developer Tools

Everyday developer utilities in one place — formatters, encoders and decoders, hash and ID generators, and the small conversions you do dozens of times a day. All client-side, all instant.

Built for the moments you don't want to leave the browser or trust a random site with a payload: format some JSON, decode a token, generate a UUID. Each tool is fast, free and runs without sending your data anywhere.

Frequently asked questions

Is the data I paste sent to a server?
No. Developer tools process everything in your browser, which matters when you're handling tokens, keys or payloads.
