What Tangokit is
Tangokit is a collection of small, free online tools: a QR code generator, a password generator, a JSON formatter, text and number tools and more. They are built for people who just want the job done, without creating an account, watching ads or wondering where their data went.
Why everything runs in your browser
A tool that runs on your device does not need your data. The text you paste, the Wi-Fi password you turn into a QR code and the number you convert never leave the page. That makes the tools private by design, and it makes them fast, because there is no server to wait for.
What to expect
- Free, with no sign-up. Open a tool and use it.
- No uploads. Input is processed on your device.
- Static QR codes stay static. They contain the data itself, so they never expire and do not depend on this website.
- Honest content. Guides explain how things work and say where a tool has limits.
- Later, carefully. Tools that genuinely need a server, such as a link shortener, may arrive one day as a clearly labelled, separate service. The browser tools will stay free and local.
