System Requirements for Running Rocket.Chat
Before deploying, ensure your server meets the following minimum hardware requirements. For a stable production deployment, we recommend using higher specifications than the minimum requirements.
- Do not purchase a server that only meets the minimum requirements. The minimum specifications represent the software's bare survival threshold and do not account for operating system overhead or production workloads. Running with only 4 vCPUs, 8 GB DDR5 RAM, and 200 GB NVMe storage can result in severe performance slowdowns, system freezes, or unexpected crashes during traffic spikes.
- For a stable deployment, we recommend using at least 8 vCPUs, 16 GB DDR5 RAM, and 450 GB NVMe storage. While lower specs might be sufficient for basic installation, consider allocating additional disk space if you plan to store recordings, logs, or other application data.
Hardware Specifications
| Resource | Minimum Requirements | Recommended |
|---|---|---|
| CPU | 4 vCPUs | 8 vCPUs |
| RAM | 8 GB DDR5 | 16 GB DDR5 |
| Storage | 200 GB NVMe | 450 GB NVMe |
Software Components
- MongoDB: Version 8.0 or later is required for Rocket.Chat 8.2 and newer. It must be installed and maintained separately if you are not using the official Docker or Helm deployments.
- Node.js: Version 22.16.0 is bundled with the official Docker image and Helm chart. For manual installations, you must match this version.
- Deno: Version 2.3.1 is required and used by the Apps-Engine runtime. Also bundled with official Docker and Helm deployments; otherwise, must be matched manually.
Network Ports Requirements
| Port | Protocol | Purpose |
|---|---|---|
| 443 | TCP | Primary entry point for HTTPS traffic (web, desktop, mobile clients) |
| 80 | TCP | Initial HTTP connection, redirects to 443 for secure access |
Ensure these ports are open and properly routed in your VPS environment for Rocket.Chat to be accessible.
