Local by default
Most tools do their work inside your browser, so everyday input does not need a trip to our servers.
Why we exist
Small tools should still feel thoughtfully made.
PlainUtils is an open-source collection of focused browser utilities for developers, writers, students, and anyone who just wants to finish a task without an account, an advert maze, or a ten-step setup.

The idea
Useful depth, minus the ceremony
There are plenty of websites that can format JSON or count words. Too many also bury the answer under pop-ups, demand a login, or quietly send everything elsewhere.
PlainUtils takes a simpler position: a utility should explain what it does, do it well, and get out of your way. That means sensible defaults for quick jobs and enough control when the details matter.
How we build
Four principles, used everywhere
Privacy you can see
When a tool contacts an outside service, it says so clearly on the page—before you use it.
Quick, not flimsy
Tools should open fast and still include the validation, export options, and details needed for real work.
Made for humans
Keyboard access, responsive layouts, dark mode, plain language, and a little personality all belong in utility software.
Under the hood
Modern web technology, intentionally lightweight
PlainUtils is built with Next.js, React, Tailwind CSS, Lucide icons, browser Web APIs, and focused open-source parsers. Pages are statically generated and deployed on Netlify.
Open source, open door
Help make the next small thing better
Bug reports, thoughtful feature ideas, clearer documentation, and focused new tools are all welcome.
