Where does the Go code run?

Boot.dev's compiler service compiles the project to WebAssembly. The compiled program then runs in your browser and sends its output to the console on the page.

Can I compile multiple Go files?

Yes. You can use up to five .go files in the main package, and the playground compiles all of them together.

Can I install third-party Go modules?

No. This playground does not expose go.mod or a general module installer. It supports the standard library, local source files, and a small set of preconfigured dependencies.
