How to choose encrypted messengers tools
All three messengers listed here offer end-to-end encryption and are open source. What sets them apart is who they're built for, how they're paid for and where they run.
- Pricing model. Signal is completely free. Element is freemium, so you can start for free and pay for more. Threema offers a free trial and then costs from $3/mo.
- Platforms. Signal has apps for Android, iOS, Windows, macOS and Linux. Element covers the same systems, adds a web app and can be self-hosted. Threema is listed with web and self-hosted options.
- Self-hosting and control. If your organization wants to run its own server, Element (built on Matrix) and Threema both list self-hosted deployment. Signal does not.
- Audience and integration. Signal is made for personal chats, calls and groups. Element is aimed at teams and governments that need shared workspaces. Threema serves individuals, companies and authorities, and it is the only one listed with an API.
All of this comes from the listings. We have not tested these tools ourselves.
