Generators
Private: nothing leaves your browser
Make the thing you need in a couple of clicks: a QR code for a link or a WiFi network, a password strong enough to matter, a barcode ready to print, placeholder text for a mockup, or a block of realistic test data. Everything is generated on your device and downloadable straight away.

About these tools
Generators are the tools where running locally matters most. A password generated on somebody else's server is a password somebody else's server has seen, which defeats the point entirely. These use your browser's own cryptographic randomness and transmit nothing.
The same goes for QR codes: the link, contact card or WiFi password you encode stays on your machine, and the image is drawn locally so you can download it without an account or a watermark.
Two of these were written from scratch rather than pulled from a library, and both are checked by software that has never heard of this site. The symbols from QR Code Generator are compared module by module against libqrencode and read back by a real scanner. Barcode Generator has zbar read its EAN-13, UPC-A, EAN-8 and Code 128 output back, including published codes with known values. Password Generator uses your own browser cryptographic randomness, so a password made here has never existed anywhere else.
