Why QuickDev?
Developers run into small recurring tasks every day — generate a UUID, check a hash, format some JSON. Most online tools are cluttered with ads, require sign-up, or send your data to external servers. QuickDev was built as a clean alternative: fast, minimal tools that just work.
Technology
QuickDev is built with Nuxt 3 and Vue 3. All data processing happens exclusively in your browser using the native Web Crypto API and standard JavaScript libraries — no data is ever sent to a server or logged.
