ToolKit is a collection of free online utilities built for developers, designers, and everyday users. Every tool runs entirely in the browser using Web APIs — nothing is sent to a server. 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.
Web developers and designers seeking a robust browser with advanced debugging tools and early access to new features. It's particularly useful for those working on complex web applications, requiring detailed inspections of code and network activities.
