DevSexy

DevSexy helps engineering teams handle small data tasks without sending source data to a server. The 35 free online developer tools run locally in the browser and require no account. Format and validate JSON payloads, inspect JWT headers and claims, convert Base64, test regular expressions, and compare text or configuration changes.

A native macOS app brings the same everyday workflow offline, with an immersive editor and Option shortcuts for fast tool switching. The Mac version has a trial and a one-time license. DevSexy suits developers who need quick, private utilities alongside their editor and API debugging workflow.
