signalapp/signal-desktop

Signal Desktop is the official desktop application for Signal, a private messaging service. It links with the Signal app on your phone (Android or iPhone) and lets you send and receive messages from your Windows, macOS, or Linux computer, essentially turning your computer into another device where you can use your Signal account. Signal is built around privacy. It uses end-to-end encryption, which means only you and the person you're messaging can read what's sent, not Signal, not your internet provider, and not any third party. The desktop app syncs with your phone, so your message history stays consistent across devices. This repository is specifically the source code for the desktop version of Signal. If you're not a developer, you'd simply download the app from signal.org. If you are a developer or technically curious, this is the open-source code that the app is built from, licensed under the AGPL open-source license. The app is built using TypeScript (a programming language that adds structure to JavaScript) and is maintained by Signal Messenger, LLC, an independent nonprofit organization. Signal accepts donations and relies on community contributions to maintain the project. People who want to help don't necessarily need to write code, there are many other ways to contribute described in their contributing guide.
