Whisper Systems was a company focused on the development of mobile security software, which was acquired by Twitter in late 2011. Twitter very generously made some of the Whisper Systems software available under an Open Source license (GPLv3), which has since been under open development by the community. The software has seen a number of new releases based on that open development, and we’ve been calling the project for this continued work “Open Whisper Systems.” Welcome to the project’s new home.

This is where we will be promoting, distributing, and coordinating the continued development of mobile security and privacy software. In an environment of increasingly pervasive surveillance, we want to make it as easy as possible for anyone to be able to organize and communicate securely. We hope you’ll join us.

Easy ways to get involved are filing bugs (or fixing them!), contributing to language translations (here and here), creating user documentation, or joining the mailing list. We appreciate all the help we’ve gotten thus far, and hope the momentum continues.
