Overview
Salut à Toi, now officially known as Libervia, is a free, decentralized communication platform built on the XMPP standard, developed since around 2008 primarily by French developer Jerome Poisson, known as Goffi, with recent funding from NLnet and the NGI initiative.
Key Features
Its defining feature is a shared backend that powers many frontends, desktop, web, command-line, and text user interface, from the same account, going well beyond instant messaging to include blogging, encrypted file sharing, and audio/video calls.
Gateways let Libervia bridge to IRC, email, and, through an ActivityPub gateway, Fediverse platforms such as Mastodon, while OMEMO and OpenPGP provide end-to-end encryption for private conversations.
Pricing
Salut à Toi/Libervia is entirely free and open source, released under the GNU Affero General Public License version 3 or later, with no subscription plans, company, or sales process; it can be self-hosted or used with any compatible XMPP server.
Key Features
Multi-Frontend Architecture — One shared backend powers desktop, web, command-line, and text user interface frontends from the same account.
End-to-End Encryption — Support for OMEMO and OpenPGP encryption for private conversations.
Audio and Video Calls — Direct and group audio and video calling built on XMPP extensions.
Blogging and Microblogging — PubSub-based blogging and microblogging features built into the same platform as messaging.
File Sharing — Encrypted file transfer between contacts.
ActivityPub Gateway — A bridge that lets Libervia accounts interact with Fediverse services such as Mastodon.
Legacy Network Gateways — Bridges to IRC and email so XMPP users can reach contacts on other networks.
Decentralized Issue Tracking — Built-in tools for managing tasks and issue trackers over XMPP PubSub.
Pros & Cons
Pros
Fully free, open-source, and federated, with no vendor lock-in or subscription cost
Unusually broad feature set for an XMPP client, spanning messaging, blogging, calls, and file sharing in one platform
Multi-frontend design lets the same account be used from desktop, web, command-line, or mobile-style interfaces
Backed by NLnet and NGI funding, supporting continued development of privacy features
Cons
Long, largely solo-led development history means a smaller contributor base than major messaging platforms
Smaller user base than mainstream chat apps, so network effects and contact discovery are limited
Documentation and interface are primarily oriented toward technically comfortable users
Now branded as Libervia, which can cause confusion for people searching under the older Salut à Toi name
