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
Mattermost
Pros
Fully open-source core with self-hosted and air-gapped deployment options
Strong fit for regulated industries, government and defense customers
Playbooks provide built-in workflow automation not native to Slack
Deep integrations with developer and DevOps tooling
Lightweight architecture (single Go binary) makes self-hosting comparatively simple
Cons
Smaller app/integration marketplace than Slack or Microsoft Teams
Enterprise pricing is custom-quoted and not publicly transparent
Self-hosting requires ongoing server maintenance and updates
UI and mobile experience is generally considered less polished than Slack
Annual prepaid billing only for official Professional and Enterprise licenses, no monthly option
Use Cases
Salut à Toi
Federated Personal Messaging — Privacy-conscious individuals use Salut à Toi/Libervia as their primary XMPP client for encrypted one-to-one and group messaging without depending on a centralized provider.
Combined Blogging and Chat — Users who want to publish blog or microblog posts and chat from the same federated identity use its integrated PubSub-based blogging features.
Cross-Network Bridging — Technical users bridge XMPP conversations to IRC, email, or ActivityPub-based networks to consolidate communication in one client.
Mattermost
Incident response and DevOps workflows — Engineering teams use Playbooks to coordinate incident response with automated checklists and dedicated channels.
Regulated and government communication — Public-sector and financial-services organizations need self-hosted or air-gapped messaging to meet compliance requirements.
Secure internal team chat — Organizations that want Slack-like messaging while keeping full control of where data is stored.
