### Find a server fast

Search the live list by name or mode, filter it down, and sort by whatever matters to you.

### Works with SA-MP servers

Join open.mp and SA-MP servers from one list.

### Bring your favorites

Import your list from SA-MP, drag it into the order you like, and export it to a file.

### Keep your names handy

Your five most recent nicknames are one click away, and each server can keep its own.

### Switch without quitting

Press F9 in game to browse, switch and rejoin servers without leaving.

### Known RCEs and exploits fixed

We actively fix them in the client as they turn up, so joining a server is safer.

### Encrypted on open.mp servers

Communication between the client and open.mp servers is encrypted.

### Fully backwards compatible with existing scripts and clients

Got an old .amx lying about? Load it straight on open.mp and join from the SA-MP client.

[Getting Started](https://omp.itsneufox.com/docs)

### Runs on your hardware

Stable on Windows and Linux, with x64, ARM and macOS in nightly builds.

### New and improved scripting system

The good old Pawn, improved with a new compiler and more functions.  
The community also supports C++, Rust, TypeScript and more.

gamemode.pwn

```c
#include <open.mp>

main() {}

public OnPlayerConnect(playerid)
{
    SendClientMessage(playerid, 0x897AF1FF, "Welcome to San Andreas!");
    return 1;
}
```

Fully controllable NPCs, on foot or driving, with no plugin needed.

```c
new npc = NPC_Create("Ghost");
NPC_Spawn(npc);
NPC_SetWeapon(npc, WEAPON_M4);
NPC_Move(npc, 1958.3, 1343.1, 15.4);
```

### Extensible C++ API

Everything available in pawn, plus the universe of C++ libraries and frameworks.

### Stand out in the launcher
