L4N is a CMS for LAN parties. It’s the successor of the old CMS I build for the VSETH GECo, with a focus on flexibility, such that it can also be used for other LAN parties or even other events. It’s released under the AGPL-3.0 license, and as such you can use it for your LAN party or project. You can find the code, installation guide and more on the L4N github repo.
