# oriz·dev — developer multitool

> Keyboard-first developer multitool. Ten dev tools in one terminal-styled page: JSON, base64, JWT, URL, UUID, timestamp, cron, hash, diff, regex. 100% client-side — no upload, no signup, no API key. Optional AI polish via g4f (gpt4free) with provider failover. Static Astro + React 19, Tailwind v4, PWA-installable, hosted on Cloudflare Pages.
