About BestDev.Tools

A free, fast, and private collection of developer tools - built for developers, by developers.

Our Mission

Every developer has been there: you need to quickly format a JSON blob, encode a string to Base64, generate a UUID, or test a regex pattern. You open a search engine, find a tool, and then realize it's plastered with ads, requires you to sign up, or worse - sends your data to a server.

BestDev.Tools was built to fix that. Every single tool on this site runs 100% in your browser. No data is ever sent to any server. No accounts. No ads. Just tools that work.
