Why We Built This Many

Single-purpose tools dominate SEO. Someone searching "UUID generator" isn't looking for an all-in-one developer suite — they want a UUID. Someone searching "markdown previewer" wants exactly that. By building 65 focused, high-quality micro-tools, every query lands on a page that does exactly one thing well. No feature bloat. No confusing menus. Just the tool.

Still No Backend — And That's the Point

All 65 tools run entirely in your browser. Your JWT tokens never leave your device. Your passwords are never sent to a server. Your temperature readings stay in localStorage. When a tool genuinely needs server-side processing, we'll add Cloudflare Workers — but for now, client-side is faster, more private, and infinitely more scalable.
