Skip to main content
open.mp (Open Multiplayer) is a multiplayer server for GTA San Andreas that is compatible with SA-MP: existing SA-MP clients can connect to it. On FREAKHOSTING, SA-MP runs the original 0.3.7-R2 server configured with server.cfg, while open.mp is a separate game with its own Game settings page and config.json. Choose SA-MP to run an unchanged 0.3.7 setup; choose open.mp for an actively developed server.

​
What is open.mp?

open.mp is a multiplayer mod for GTA San Andreas made by the open.mp team. Its server replaces the SA-MP server, and its FAQ states that existing SA-MP clients can connect to it. The open.mp website also hosts the SA-MP documentation, and the open.mp team makes the open.mp launcher that players use to find servers.

​
Which one should you choose?

​
Can I use my SA-MP gamemode on open.mp?

Usually yes, with some work. The open.mp guide to moving a gamemode says to:
  1. Put your gamemode, filterscripts and plugins in the matching open.mp folders.
  2. Replace #include <a_samp> with #include <open.mp> and compile the gamemode again.
  3. Enter your gamemode in config.json (pawn.main_scripts) instead of gamemode0.
  4. For some plugins, use the open.mp build. A few, such as Pawn.CMD, Pawn.RakNet and sscanf, go in the components folder instead of plugins.
Follow the full open.mp installation guide for the current list of plugins that need an open.mp version.
