Game Server Gateway (GSG)
The World Is Your Lobby.
Let’s Network the World.
Gateway is a self-hosted multiplayer platform that gives Unity developers the infrastructure needed to build online games faster. Add accounts, login, lobbies, room creation, server discovery, and dedicated server management without giving up ownership of your backend.
Run it yourself for free or let Run Level Systems host and manage it for you. Gateway works alongside Mirror, FishNet, Netcode, or your own networking solution.
BUILD MULTIPLAYER. OWN THE NETWORK.
How Gateway Fits Into Your Game
Gateway provides the multiplayer infrastructure layer around your game. It handles accounts, login, lobbies, room creation, server registration, and server discovery while allowing developers to continue using Mirror, FishNet, Netcode, or another networking framework for gameplay.
Why Gateway?
No Vendor Lock-In
Your players, your database, your servers.
Free To Self Host
Run Gateway yourself with SQLite or MySQL/MariaDB.
Networking Framework Neutral
Use Mirror, FishNet, Netcode, or your own networking solution.
Multiplayer Ready Faster
Focus on your game instead of building account systems, lobbies, and matchmaking infrastructure.
Optional Managed Hosting
Run Level Systems can host and manage Gateway for you.
Gateway is not a networking library.
Gateway handles the multiplayer infrastructure around the game. The networking framework handles gameplay, player movement, RPCs, and the live session transport.
Gateway vs Cloud-Only Multiplayer Services
Many developers use cloud services because they simplify multiplayer development. Gateway takes a different approach. Instead of locking developers into a single cloud provider, Gateway allows complete ownership while still providing the convenience of managed hosting when desired.
| Category | Cloud Service | Gateway |
|---|---|---|
| Ownership | Vendor controlled | Developer owned |
| Cost Model | Monthly usage costs | Free to self-host |
| Backend Control | Backend ownership limited | Complete ownership |
| Deployment | Usually cloud-first | Self-hosted first |
| Dependency | Developer dependent on provider | No vendor lock-in |
How Gateway Works
1. Import Gateway SDK
Developers bring Gateway into the project and connect it to the existing multiplayer stack.
2. Configure Game ID and API Endpoint
Set the game identity and backend endpoint for the lobby and server directory.
3. Player Logs In
Accounts and login are handled before the player enters the live match layer.
4. Player Creates or Joins a Lobby
Gateway manages room creation and lobby browser behavior.
5. Gateway Allocates or Discovers a Server
Dedicated server selection, registration, and discovery happen through the Gateway layer.
6. Game Connects Through the Multiplayer Adapter
The game keeps using Mirror, FishNet, Netcode, or another transport adapter for gameplay.
7. Players Connect and Play
The live session remains inside the game networking framework.
8. Gateway Tracks Status
Server heartbeats and session state keep the lobby directory current.
Own The Whole Stack
Gateway can operate in multiple modes depending on the project and deployment target.
SQLite Self Hosted
Perfect for development and smaller projects.
MySQL/MariaDB Self Hosted
Recommended for production deployments.
Run Level Systems Hosted
Managed databases, monitoring, backups, server launching, and support.
