Hi everyone! I built Mianju Toolbox because I was tired of online tools that force you to sign up, track your data, or bombard you with ads. I wanted something simple — just open a tool and use it, no strings attached. The toolbox includes 30 utilities across developer tools, text processing, math & conversion, and everyday utilities. Some favorites: JSON formatter, password generator, QR code maker, age calculator, and color picker. Everything runs in your browser, no data is sent to any server. Would love to hear what tools you'd like to see added next!
