Flowthera Toolbox
Everyday developer utilities that work offline, no AI required.
The small tools you reach for every day, in one place and fully offline: format and convert data, compare text, test a regex or an API call, decode a token. Nothing you paste is sent anywhere.
Part of Flowthera Studio, the free desktop app.
