Frequently Asked Questions

? Is Rocket.Chat hard to install?

It’s relatively easy to install using Docker (a single command) or pre-built packages for major OSes. For complex deployments like Kubernetes, some technical knowledge is helpful, but comprehensive documentation and community support simplify the process.

? Is it a good alternative to Slack?

Yes—Rocket.Chat offers most of Slack’s core features (messaging, calls, integrations) plus full data ownership and customization options that Slack lacks, making it ideal for privacy-conscious teams or enterprises needing compliance control.

? Is it completely free?

The core platform is open-source (MIT license) and free to use, self-host, or modify. Paid enterprise plans exist for additional support, advanced security features, and managed hosting, but no fees are required for the basic self-hosted version.
