About Go Playground
The Go Playground is a free web tool for writing, running and sharing Go programs. It runs code on go.dev's servers inside a sandbox, so you do not need a local Go installation.
What it does
You write or paste a program and press run. The service vets, compiles and runs it, then shows the output on the page. You can format the code or share it by link. The sandbox limits what a program can do, so it can only write to standard output and standard error.
Key features
- Run and format Go code in the browser
- Share a snippet with a link
- Run tests when a program has no main function
- Most of the standard library available
- Fixed clock makes output repeatable between runs
Who it's for
People learning Go, developers who want to test a small idea, and teachers who show examples in class. It is a quick way to try language features without any setup.
Pricing and good to know
The playground is free to use and runs the latest stable Go release. Programs face limits on execution time, CPU and memory, and some standard library packages are not available. Benchmarks are generally not supported. Treat shared links as public, and do not paste secrets into a program.
