Salut à Toi

Salut à Toi is a self‑hostable, libre communication platform that supports multiple front‑ends and operates without subscription fees. It implements XMPP with extensions for audio/video calls, group conferencing via mesh (MUJI) and selective forwarding (SFU), remote desktop control, and an email gateway that maps email and mailing lists to XMPP forums. The system also includes thread handling, data‑policy indicators, and pubsub features.

The software targets users who want a decentralized alternative to mainstream messaging services, including individuals and organizations that prefer to run their own server and retain control over data. Developers and sysadmins can benefit from the open‑source AGPL‑3.0 codebase, which is packaged for Debian, Arch Linux, and NixOS and can be installed with modern Python tooling such as uv.

Distinctive aspects include a focus on reducing XMPP metadata, a web‑centric user interface, and experimental support for peer‑to‑peer mesh calls and selective‑forwarding units. The project is actively maintained, with recent work on simplifying installation and expanding multimedia capabilities.
