Signal vs Element Comments
Signal is a centralized System, while with Element you can interact with everyone in the federated Matrix-Network.
Signal is a simple centralized messaging app. However, if your target is achieving maximum security and having a simple and easy to use interface instead of self-hostability go for Signal. Use Element/Mattermost/Rocket Chat for self-hosted channel-wise team chat.
- Signal is Free and Open Source
- Signal is Security-focused





















































not a self-hosted solution or an enterprise system
