Jami as a Linux alternative to Signal
Updated
Our verdict
Jami can replace Signal for users who value a fully peer‑to‑peer architecture and are comfortable with a slightly different workflow. It offers encrypted one‑to‑one and group chats, voice/video calls, and file sharing on Linux, so the core use‑cases are covered. Power users or small teams that need SIP integration or on‑premises deployment will find Jami especially attractive, while people who rely on Signal's large user base, sealed‑sender metadata protection, and the simplicity of a single server‑backed service may prefer to stay with Signal.

What works the same
- End‑to‑end encrypted one‑to‑one messaging
- Group chats with encryption
- Voice and video calling
- File and media sharing
- Cross‑platform clients (Linux, Windows, macOS, Android, iOS)
What is different
- Jami uses a pure peer‑to‑peer network; Signal relies on centralized servers
- Signal provides sealed‑sender metadata protection, which Jami does not offer
- Signal has a larger user base, making contact discovery easier
- Jami includes SIP client support and enterprise extensions that Signal lacks
- Signal stores chat backups in encrypted form; Jami stores messages locally without a cloud backup option
Opening your Signal files
Signal stores encrypted backups as a single file that can only be read by the Signal app. Jami does not provide a tool to import those backups, and there is no documented way to export Signal chats into a format Jami can read. If you need to keep old conversation history, you will have to export it manually (e.g., copy text) before switching.
Switching from Signal to Jami, step by step
- Install Jami from your distribution's repository or via Flathub.
- Create a new Jami account (you can use a local or JAMS account).
- Add contacts by exchanging Jami IDs or QR codes.
- Export any important messages from Signal (e.g., copy text or use Signal's export feature).
- Inform your contacts to switch to Jami and share your Jami ID.
- Test a one‑to‑one chat and a voice call to verify everything works.

How to install Jami on Linux
flatpak install flathub net.jami.Jamisudo apt install jamiFrequently asked questions
Can Jami interoperate with Signal users?
No. Jami and Signal use different protocols, so you cannot message or call a Signal user from Jami.
Is Jami's encryption as strong as Signal's?
Both use end‑to‑end encryption, but Signal adds extra metadata protection (sealed sender) and has undergone more extensive public audits.
Will Jami work on a restricted corporate network?
Because Jami is peer‑to‑peer, it may need open ports or NAT traversal; using the optional JAMS server can help in tightly controlled environments.
