I made this because I was frustrated with tool sites that require sign-ups, track you, or send your data to a server just to format some JSON.

UtlKit has 170+ tools (JSON/YAML/SQL formatter, regex tester, hash generator, password tools, image utilities, audio utilities etc.) and everything runs in your browser. No sign-up, no tracking, no server-side processing.

Built with Next.js 15 + Cloudflare Pages. Zero hosting cost.
