Requirements for Rocket.Chat Deployment

As of December 15, 2023, Rocket.Chat has ceased support for connections from cloud services and official mobile/desktop apps to workspaces running legacy versions outside our support window. Users on unsupported legacy servers are advised to upgrade to the latest Rocket.Chat version to ensure continued access to cloud, mobile, and desktop applications. Each Rocket.Chat version is supported for six months post-release.

When preparing to deploy your Rocket.Chat workspace, it's essential to consider the necessary software and hardware requirements to ensure a successful deployment.

These requirements vary significantly with the following:

• Number of concurrently active users

• Number of actually connected devices per user

• Users' activities: Solely text-based messaging takes minimal resources, while file sharing and jpg uploads will consume more resources. This is because a set of computations has to be done on these files.

• Bot or integration activity level: Different bots and integrations have different requirements.

Hardware Requirements

1. Virtual Private Server (VPS)

A VPS is a virtual machine offered as a service by a hosting provider or cloud service, allowing users to access and manage their own isolated server environment.

Minimal VPS requirements

This minimal virtual setup, if not over-provisioned, is suitable for small deployments of up to 200 users, and 50 concurrent active users, with limited mixed uploads, sharing, and bot activities.

• Single-core (2 GHz)

• 1 GB RAM

• 30 GB of SSD

Recommended VPS requirements

If not over-provisioned, the recommended virtual configuration can handle small deployments with up to 500 users, 100 concurrent active users, and moderate levels of mixed uploads, sharing, and bot activities.

• Dual-core (2 GHz)

• 2 GB RAM

• 40 GB of SSD

1. Small Office Server

This configuration can support a small office or group of up to 50 users, with 25 concurrently active users and moderate levels of mixed uploads, sharing, and bot activities. It relies on a managed MongoDB service (mlab.com), as running MongoDB locally on a Pi is not advised.

• Raspberry Pi 3 or Pi 2

• 4 cores 1 GB memory

• 32 GB SD card ($15)

1. Bare-metal server

This minimal hardware configuration is ideal for corporate or groups with up to 1,000 users, up to 300 concurrently active, and moderate levels of mixed uploads, sharing, and bot activities.

• Intel Xeon E5-2603 v4 (or equivalent) [1.7 GHz, 6 cores, $213 USD]

• 4 GB RAM

• 500 GB hard disk or larger
