Pros & Cons
Salut à Toi
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
Centrifugo
Pros
Free, Apache 2.0-licensed core with no per-connection or per-message fees
Production-proven at scale by companies including VK, Badoo, ManyChat, and Grafana
Supports multiple transports and scaling backends rather than locking teams into one stack
Broad official SDK coverage across web, mobile, and backend languages
Cons
Requires engineering effort to deploy, secure, and integrate versus a plug-and-play hosted API
Centrifugo PRO pricing is not publicly listed, requiring direct contact for enterprise features
Self-hosted operation means the adopting team is responsible for uptime, scaling, and monitoring
No official company headquarters or large support organization behind the open-source core
