Radarr 4K

A frequently asked question we get from customers is if we have support for Radarr 4K. At the time of writing, we don't officially support it, but it can be installed using a script a community member has written.

Radarr is a movie collection manager for Usenet and BitTorrent users. It can monitor multiple RSS feeds for new movies and will interface with clients and indexers to grab, sort, and rename them. It can also be configured to automatically upgrade the quality of existing files in the library when a better quality format becomes available.

To follow this guide, you will need to SSH into your server. If you need help with this, please refer to the how do I connect article.


These tools are not officially supported. Please consider reaching out to our Discord for unofficial community-driven support on anything listed below.


Before installation, please consider reading the installer script. You can read it on the GitHub Repo. You can run the script by using the following command:

bash <(curl -sL "")

If something goes wrong during your install, please consider checking the logs and the output in your console. You may find them by running the following:

less -r +G ~/.logs/radarr4k.log

These can be helpful in cases where you need to see the output from installation.

On first run, go to http://<>:<yourportnumber> to access Radarr 4K. This should ask you for credentials. Keep in mind that this application is exposed on the public internet.

Controlling the Systemd Service#
