Signal Desktop8.33.0

Send and receive Signal messages from a Linux computer while keeping conversations connected to your Signal contacts. Signal must already be installed on your phone before Signal Desktop can be used, allowing you to continue those phone-based conversations from the desktop.

Messages and calls use end-to-end encryption built on the open-source Signal Protocol. The service is designed to deliver messages quickly and reliably even across slow or constrained networks, and it supports high-definition voice and video calls over both short and long distances. A dark theme provides an alternative appearance, while the service operates without advertisements or trackers.

Signal Desktop suits people who want private messaging and calling for conversations with friends, family, coworkers, or other contacts from a Linux workstation. Signal can use an existing phone number and address book to help you find and communicate with those contacts, with its privacy-preserving protections enabled as a standard part of the service rather than an optional mode.

Snapcrafters publishes this open-source communication software for Linux. The current 8.28.0 version requires Linux and snapd, and supports x86_64 (amd64) architecture.
