System requirements

Note: The configurations described below are what we use and test against. This means that other configurations might also work but we do not provide any official support for them.

Server

Hardware

• Memory: 4096 MB
• Free disk space: 2 GB

Operating system

The package-based installation requires one of the following Linux distributions:

Distribution (64 bits only)
Ubuntu 18.04 Bionic Beaver
Ubuntu 16.04 Xenial Xerus
Debian 10 Buster
Debian 9 Stretch
CentOS/RHEL 8.x
CentOS/RHEL 7.x
Suse Linux Enterprise Server 12

The docker-based installation requires a system with Docker installed. Please see the official Docker page for the list of supported systems.

Overview of dependencies

Both the package and docker based installations will install and setup the following dependencies that are required by OpenProject to run:

• Runtime: Ruby Version = 2.6.x
• Webserver: Apache or nginx
• Application server: Puma
• Database: PostgreSQL Version >= 9.5

Client

OpenProject supports the latest versions of the major browsers. In our strive to make OpenProject easy and fun to use we had to drop support for some older browsers (e.g. IE 11).

• Mozilla Firefox (At least ESR version 60)
• Microsoft Edge
• Google Chrome
• Apple Safari
