DevKit vs DevGear

DevKit puts 30 developer utilities in your pocket — and every one runs entirely on your device. Stop juggling browser tabs. Stop pasting production tokens into random websites. Format JSON, decode a JWT, test a regex, or convert a timestamp on a train, on a plane, or inside a locked-down corporate network. YOUR WORK STAYS ON YOUR DEVICE > Every tool runs locally. The JSON you paste, the token you decode, the certificate you inspect — none of it is uploaded to a server, and none of it is visible to us. > All 30 tools work with no internet connection. > No account, no sign-up, no email required.
