Where does my Go code run?

On a sandboxed third-party execution service, not on induwara.lk's servers. Your code is sent to an isolated compiler environment, run there, and the result is returned. Our server only forwards the request (with strict rate limits and size caps) — it never executes your code, so there's no way for a program to reach our systems.

Is the Go compiler free to use, and do I need an account?

Yes, it's completely free and there's no signup. Just write your code and press Run. It's meant as a quick, zero-setup way to compile and test code from any device, including a phone.

What program structure do I need?

A `package main` with a `func main()` entry point, as the default snippet shows. Import standard-library packages as needed. Output via fmt.Print/Println appears in the output panel.

Is this good for learning Go?

Yes — it's a quick, install-free way to try Go's syntax, goroutines basics, slices, and the standard library from any device. Great for following a tutorial or testing a snippet.

Which compiler / version is used?

It uses a recent Go release, so modules of the standard library (fmt, strings, sort, etc.) and modern Go syntax work.

Are there limits on run time or code size?

Each run has a 30-second limit and a 50 KB code-size cap, and there are per-IP and overall rate limits so the shared compiler stays fast for everyone. For big projects use a local toolchain; this is built for snippets, exercises, and quick tests.

Can I read interactive input (stdin) while it runs?

Interactive input isn't wired into this editor yet — programs run start-to-finish and their output is shown. For exercises that need input, set the values directly as variables in your code. Everything printed to standard output appears in the output panel.

How it works

Go compiles to a native binary with the Go toolchain — not a browser task. The server compiles your package main and runs it, returning fmt.Println output. The standard library is available.

When you press Run, your Go code is sent to a sandboxed execution service that compiles and runs it in an isolated environment, then returns the output. It does notrun on induwara.lk's servers — our site only proxies the request, so your code can never touch our systems, files, or other users. Languages like Goneed a real compiler/runtime, which isn't practical in a browser, so this is the safe way to offer them.

The proxy is strictly bounded: a 30-second execution limit, a 50 KB code cap, and per-IP plus global rate limits that protect the shared compiler. There's no signup and nothing to install — write code, hit Run, read the output.
