Hi Fazier! DevSexy brings 35 developer utilities into one workspace: JSON formatting, JWT inspection, Base64 conversion, regex testing, text diff, and more. The free browser tools process inputs locally. The native offline Mac app adds global Option shortcuts and a shortcut HUD, with a 15-day trial and a one-time license for the purchased version. I would welcome feedback on the tools and the workflow.
