The toolkit includes a cryptographically secure password generator (with 20+ specialized variants for WiFi, banking, SSH, and more), a word counter with keyword density analysis, a JSON formatter and validator, a regex tester with live match highlighting, a QR code generator with PNG/SVG export, a color converter (HEX/RGB/HSL/CMYK), Base64 encoder/decoder, UUID v4 generator, hash generator (SHA-256/512), URL encoder, case converter, lorem ipsum generator, markdown editor with live preview, color palette generator, and a username generator. Built with Next.js and TypeScript, deployed on Vercel. New tools added regularly.
