GODOT MULTIPLAYER · ALPHA

Online multiplayer for Godot, without the backend.

SpawnWeaver is a hosted multiplayer backend for Godot games. Drop in a native SDK, point it at your server, and add rooms, lobbies, matchmaking, realtime events, and player saves with a few lines of GDScript — no servers to write.

How it works

Sign in & create a project. Name it to get a public key (safe to ship in your game) and a secret key (server-side, shown once).
Install the Godot SDK in one line. Run the installer from your project root — it drops the addon into res://addons. Then enable the plugin.
Connect & play. Paste your key + server URL into the editor dock, write a few lines of GDScript, and run two instances to see two players together.

# 1. install (from your Godot project folder)
iwr https://your-domain/install.ps1 -UseBasicParsing | iex

# 2. connect in GDScript
MultiplayerService.connect_using_config()      # uses your saved key + URL
MultiplayerService.create_room("Alice")        # share the room code
MultiplayerService.send_event("player_moved", { "x": 10, "y": 5 })

What you get

🎮 Godot-native SDK

An autoload client with signals, guest auth, auto-reconnect, and clear errors — feels like part of Godot.

🚪 Rooms & lobbies

Create or join by code, public lobby lists, ready checks, and host controls.

⚔️ Matchmaking

Queue players by mode and region; the server pairs them into a room.

📨 Realtime events

Relay game events to everyone in a room with a single call.

🔄 State sync

Shared room state and per-player entities, with snapshots for late joiners.

💾 Player saves

Store profiles, progression, and inventory with project-scoped key-value storage.

🔍 Multiplayer debugger

Session timelines, an error explorer with suggested fixes, and a debug-report viewer.

One Docker Compose stack on a small VPS — automatic HTTPS, your own domain.
