KitDev Space builds developer tools on a browser-first privacy rule

Developer tool platform KitDev Space was built around a single guiding principle: run all processing in the browser and use a server only when the browser genuinely cannot do the job. The rule was inspired by a common habit among developers of pasting sensitive data like JWTs and .env files into third-party online tools without knowing where that data goes. Most everyday developer tasks — including hashing, encryption, image editing, and archive inspection — are handled entirely client-side using built-in browser APIs such as Web Crypto and OffscreenCanvas. Server-side processing is reserved for specific cases, such as tools requiring native libraries, cross-origin network requests, or inputs too large for a browser tab. When a server path is used, the platform discloses this to users explicitly rather than processing data silently on a remote machine.
