junkbox

Junkbox is a physics-based sandbox game inspired by classics like Garry's Mod. Spawn props, stack junk, experiment with chaos, and host your server using Node.js and LocalTunnel.

You can play directly in your browser and join servers hosted by other players, or run your own and share the link. Each server is self-hosted and easy to set up.

Junkbox is built for creative freedom and simple, moddable fun. Whether you're building towers or creating destruction, you have full control over the sandbox.

Junkbox is moddable on the server side. Players can edit the included relay server to customize how connections are handled, routed, or filtered. They can also modify the launch script to configure ports and custom subdomains.
