# SpawnWeaver

> Multiplayer backend for Godot 4: rooms, matchmaking, realtime state sync,
> events/RPC, player storage, and leaderboards over one WebSocket, driven by an
> awaitable GDScript SDK (`SpawnWeaver` autoload + drop-in nodes). Hosted service;
> anonymous-first player identity; free tier available.

## Getting started

- [Quickstart](https://spawnweaver.dev/dashboard/docs/quickstart): Two players moving in under five minutes.
- [Installation](https://spawnweaver.dev/dashboard/docs/installation): Install the Godot SDK, enable the plugin, and configure your project key.
- [Core concepts](https://spawnweaver.dev/dashboard/docs/concepts): The mental model — projects, players, rooms, events, state, and storage.
- [Adding multiplayer to your game](https://spawnweaver.dev/dashboard/docs/adding-multiplayer): The end-to-end path — from installing the addon to shipping, for a new game or an existing single-player one.

## Guides

- [Rooms](https://spawnweaver.dev/dashboard/docs/rooms): Create, join, list, and manage rooms — codes, rosters, hosts, and the disconnect grace window.
- [Matchmaking](https://spawnweaver.dev/dashboard/docs/matchmaking): Queue players by mode, region, and size — one awaitable call from search to room.
- [State sync](https://spawnweaver.dev/dashboard/docs/sync): Room state, entities, and the SpawnSync and PlayerSpawner nodes — persistent live state for your room.
- [Events](https://spawnweaver.dev/dashboard/docs/events): Fire-and-forget messages relayed to the other players in your room.
- [Players & identity](https://spawnweaver.dev/dashboard/docs/players): Anonymous-first identity that survives restarts — no accounts, no login screens.
- [Player storage](https://spawnweaver.dev/dashboard/docs/storage): Persistent per-player key-value storage — save games without running a server.
- [Debugging](https://spawnweaver.dev/dashboard/docs/debugging): SDK logging, debug bundles, and the dashboard's multiplayer debugger.
- [Leaderboards](https://spawnweaver.dev/dashboard/docs/leaderboards): Ranked score boards — submit, top lists, and around-me windows without writing a backend.
- [Steam integration](https://spawnweaver.dev/dashboard/docs/steam): Join via the Steam friends list, invites, and persona names — with GodotSteam.
- [Offline mode](https://spawnweaver.dev/dashboard/docs/offline-mode): Prototype and test with zero signup — no server, no account, no network.
