matrix
This chat system provides companies with a decentralized, open-standard protocol that helps with data sovereignty, interoperability, and scalability. It eliminates vendor lock-in at the same time supporting enterprise-grade features like end-to-end encryption and other integrations. This makes it a good choice for businesses prioritizing control, cost efficiency, and long-term flexibility in communication.
It operates on an open protocol that is used for secure, decentralized real-time communication, helping users and organizations to run their own servers while connecting across a global network. Where as proprietary solutions they centralize data on vendor clouds, matrix's federated model distributes control, allowing companies to maintain full ownership of their conversations and metadata. This architecture is good for enterprises wary of data breaches or policy shifts in platforms like Slack, where outages in 2021 disrupted thousands of teams.
For FOSS competitors, matrix is good for natively supporting federation without the silos common in self-hosted tools like Rocket.Chat, which require cumbersome bridges for external communication. Companies adopt matrix to future-proof their workflows.
The protocol's event-based design ensures reliable message syncing across devices, with historical context preserved indefinitely on self-managed storage. This reliability goes beyond Discord's free tiers or Teams' dependency on Microsoft 365 licensing.
As remote work persists places value matrix's ability to scale from small teams to enterprise deployments without performance degradation, hosting on lightweight servers that consume minimal resources compared to resource-heavy Mattermost instances.
Decentralization and Data Sovereignty
The real appeal is its decentralized federation, where each organization controls its homeserver, yet messages flow freely between servers worldwide. This is different with proprietary platforms like Slack or Teams, which store all data on centralized clouds vulnerable to single points of failure, as seen in Slack's 2023 global outage affecting millions.
Companies in regulated industries, such as finance or healthcare, choose matrix to comply with stringent data residency laws like GDPR, HIPAA, or Japan's APPI, keeping sensitive patient records or transaction logs on-premises without third-party access.
FOSS alternatives like Mattermost offer self-hosting but lack true federation, creating isolated islands of collaboration with partners.
Interoperability and Bridging Capabilities
Its good in interoperability, with official and community bridges connecting natively to over 50 protocols including Slack, IRC, Telegram, Discord, and Microsoft Teams.
For Example: A sales team on matrix can message clients on WhatsApp via puppet bridges, pulling full conversation history without data loss or app-switching.
What does it take to self-host
Self-hosting a matrix server, generally using Synapse as the homeserver implementation, requires a Linux server like Ubuntu or Debian with decent resources around 2-4GB RAM, 1-2 CPU cores, and 20-50GB storage for small-scale use. A public IP address or dynamic DNS setup is needed, along with a domain name configured with DNS records
Required software includes a reverse proxy like Nginx or Apache for handling HTTPS traffic on ports 80/443 and proxying to Synapse's ports (8008 for client-server, 8448 for federation), plus SSL certificates from Let's Encrypt.
So...Install Synapse via Debian packages, pip, or Docker, generate a signing key, and then configure a homeserver.yaml with a domain, then for a database use SQLite for small setups or maybe PostgreSQL for scale, and finally configure the TURN server settings for VoIP using Coturn
For a client like Element, you an serve it via another subdomain with a custom config.json pointing to your matrix homeserver.
You can choose to federate or not...just depends on what you needs are
Federation with other matrix servers does requires proper delegation headers in the proxy config; and for non-federated setups they simplify port exposure.
What does Federation mean
This referes to the decentralized process where multiple independent homeservers interconnect and share data, enabling users on different servers to communicate without a central authority(Not one organization is storing all conversations)
Homeservers use the Server-Server API over HTTPS to replicate JSON events like messages, room state changes, or membership updates across participating servers in a room, following eventual consistency for stability even if some servers go offline. Each event is cryptographically signed by the originating server, preventing tampering, and pushed in a full-mesh topology to ensure all joined servers maintain a shared conversation history.
This creates an open network similar to email, supporting features like end-to-end encryption, VoIP, and bridging to other protocols, with no single point of failure.
You do not have to federate
When matrix is deployed, federation is not enabled by default in many configurations. It requires explicit setup like DNS SRV records, .well-known endpoints, or exposing port 8448 publicly.
This private mode keeps all data, rooms, and calls (via self-hosted TURN like Coturn) on your infrastructure, helping privacy and control without E2EE reliance for internal trust.
