What Go Playground is

Go Playground is a free web service for compiling and running Go programs in a sandbox. Submit code and the service vets, compiles, links, and runs it, then returns the output. The interface includes Run, Format, and Share controls. If a program includes tests or examples but no main function, the service runs those tests. It uses the latest stable Go release and supports most of the standard library, with some exceptions. Each run starts at 2009-11-10 23:00:00 UTC, giving program time a fixed value. Execution time, CPU use, and memory are limited; programs can communicate outside the sandbox only through standard output and standard error. Sharing is public-only, and the service has no private projects, real-time collaboration, full-stack runtime, or deployment options. Benchmarks are likely unsupported because of the sandbox's limited resources. The Go project's public source repository includes the service's source code. For questions about using Go, the project points users to the golang-nuts discussion mailing list. Other sites wishing to use the service must contact the project first, use a unique user agent, and offer a service that benefits the Go community.

Who it suits

It suits people who want to compile and run Go code in a browser, including programs with tests or examples. It is less suited to work requiring private projects, collaboration, deployment, or unrestricted runtime resources.

What it does well

  • Free web access with Run, Format, and Share controls.
  • Runs programs and tests in a sandbox.
  • Uses the latest stable Go release.
  • Most of the standard library is available.
  • Source code is publicly available.

What to know first

  • Execution time, CPU, and memory are limited.
  • Sharing is public-only; private projects are unavailable.
  • Programs can communicate externally only through stdout and stderr.
  • Benchmarks are likely unsupported.

Limits

The free plan limits execution time, CPU, and memory, and exposes only most of the standard library. Programs can communicate externally only through standard output and standard error.

As go.dev lists them, read 7 Oct 2026. The maker's own page has the final word.

Getting started

  1. Open https://go.dev/play/ in a web browser
  2. Enter or paste a Go program
  3. Select Format if you want the code formatted
  4. Select Run to compile and execute it
  5. Use Share to create a public share

Verdict

Go Playground provides a straightforward browser-based way to run Go code and tests. Its sandbox and public-only sharing make it a limited fit for workloads that need more resources, privacy, or deployment options.
