As a developer, I was tired of Googling for a simple JSON formatter or Base64 encoder every time — clicking through ad-heavy sites and closing popups just to format some text. So I built DevToolBox: 100+ tools in one place, no signup, no tracking, completely free and open-source. Would love to hear what tools you'd like us to add next!
