In SCP: Labrat, there are two different ways to play multiplayer with others

  • Relay Lobbies
  • Dedicated Servers

Relay Lobbies

A lobby is hosted by one person, and others can join by using a unique identifier, also called a lobby code. Anyone can easily host a relay lobby using the in-game host buttons.


  • No need to share IP addresses, port forward, or use hacky NAT tricks
  • Easy to setup
  • Great for one-time games with friends


  • High latency
  • Single point of failure (relay goes offline or host disconnects/leaves, the lobby is closed)

Dedicated Servers

A dedicated server is hosted by community members, and is able to be online 24/7. Although anyone can host a server, there are some requirements that must be met.


  • No single person has to be online for the server to be online for others
  • Great for building a community


  • Requires the server owner to port forward
  • Not as easy to use
