Matrix vs Slack: Self-Hosted Team Chat in 2026
Your team needs chat. The question is: who should own the conversation — a company in San Francisco, or you? Slack is easy. Everyone knows Slack. But every year, more businesses are asking the same question: why are we paying forever for something we could run ourselves? Matrix is the answer for a growing crowd. Let's compare them honestly — no hype, no jargon walls. What you actually pay Slack's…
Slack and Matrix are two popular team chat options for businesses. While Slack offers ease of use and quick setup, Matrix provides self-hosting capabilities, cost savings, and enhanced privacy. Slack's paid plans start at $8.75 per person per month, making a 20-person team cost about $175 per month, forever. In contrast, Matrix is open source, meaning there is no ongoing cost for the software itself.
A small server (like a $5-10 VPS) and a domain are all that's needed for a small team, which adds up to roughly $10 per month.
Privacy is a significant difference between the two. With Slack, all messages are stored on Slack's servers, potentially exposing sensitive internal conversations to the company. With Matrix, the server and data are controlled by the organization, allowing them to choose the jurisdiction and ensure data security. Self-hosting Matrix, however, is not a simple task for beginners.
It involves installing the Matrix server with Docker, setting up a domain and HTTPS certificates, configuring proper registration, and regularly updating the system. This process is comparable to any serious IT setup and requires proper maintenance.
Slack still holds an advantage in terms of polish, ease of use, and having extensive integrations. However, Matrix is catching up and offers interoperability with other Matrix servers and the ability to bridge with Slack, Teams, and WhatsApp. The key takeaway is that businesses should choose based on their needs and priorities. Slack is an appropriate choice for small startups looking for quick setup and convenience, while Matrix is ideal for larger teams concerned about cost, privacy, and avoiding vendor lock-in.
