A minimalist collection of web-based tools built with a strong emphasis on privacy, speed, and simplicity. Each tool is crafted to run without JavaScript, cookies, or tracking, and is under 14kB in size. The homepage prominently states this mission, underscoring the site’s commitment to providing functional, distraction-free utilities. The tools cover a range of practical needs including unit converters (for length, energy, pressure, etc.), SVG converters for web development, and simple randomness generators.
The site is organized by categories, each offering single-purpose tools accessible via clean, fast-loading interfaces. With no popups or external dependencies, InputOutput.dev is especially well-suited for developers, minimalists, and users concerned with digital bloat or privacy. Its utility-focused design removes friction from common tasks while showcasing how effective a well-built static toolset can be. While the author is not explicitly credited on the homepage, the presence of a “Buy me a coffee” button suggests it’s the work of a solo developer or small independent creator.
