Open Source Encrypted Communication Software

Encrypted Communication software secures the exchange of text messages, voice calls, and video streams. These tools use end-to-end encryption to ensure that only the intended recipients can read the shared content. This type of software prevents unauthorized parties from intercepting private conversations or accessing shared files. It is for individuals and organizations that need to manage their own messaging servers to keep metadata and chat histories off corporate clouds. Self-hosting these apps allows you to define who accesses the network and how communication logs are stored.

This page lists 34 open source tools in the Encrypted Communication category. The most popular are LocalSend, AdGuard Home and Tailscale. Most use the AGPL-3.0 or Apache-2.0 license, and 27 offer an official Docker image.
