The tools span the full developer workflow: data tools for formatting and converting JSON, YAML, SQL, and XML; text tools for encoding, diffing, and transforming strings; web tools for working with HTTP, cron schedules, and API debugging; security tools for generating passwords, computing hashes, and decoding JWTs; generator tools for UUIDs, QR codes, lorem ipsum, and test data; visual tools for CSS gradients, box shadows, and color conversion; and fun tools for Morse code, ASCII art, and typing practice.

All tools are built with vanilla JavaScript and run offline-capable in modern browsers. No frameworks, no build steps, no megabyte bundles — just fast, focused utilities that load in under a second.
