Build your game, piece by piece.
Pick a game base. Add modular systems like inventory, currency, and leveling. Drop in compatible extensions. SboxAddons is the plug-and-play marketplace for s&box.
How it works
Start with a foundation, then snap in the systems you need
Pick a Game Base
Choose a foundation for your game. Game bases provide core functionality like networking, player management, and the framework other addons plug into.
Add Systems
Snap in modular systems — inventory, currency, leveling, hotbar, admin tools, scoreboard. Each one is plug-and-play and designed to work with your game base.
Extend & Customize
Add compatible extensions — vehicle systems, property ownership, maps, weapons, HUDs, and more. Everything is designed to integrate with existing systems.

Everything you need to build your s&box game
Modular by design
Every addon on SboxAddons is built to integrate. Game bases define the foundation. Systems plug into them — inventory, economy, leveling, ranks. Extensions add depth — vehicles, property ownership, crafting. You pick what you need and they just work together.
No code required. Just browse, install, and build your game like snapping together blocks.
