The Rust Playground is a web service that lets users write, compile, and run Rust code in the browser without installing anything. It supports stable/beta/nightly toolchains, popular crates, rustfmt and Clippy, sharing via GitHub Gists, and viewing LLVM IR, assembly, or MIR output.

Use cases

• try out Rust code without installing the compiler
• share a Rust code snippet with a friend via a link
• test whether a snippet compiles on stable, beta, or nightly Rust
• run rustfmt or Clippy on a small piece of Rust code
• inspect the LLVM IR, assembly, or MIR generated from Rust source
• experiment with popular crates like those in the Rust Cookbook
• reproduce a compiler error or ICE to report an issue

When to choose

• you want to quickly experiment with or demo Rust code in a browser
• you need a sandboxed environment to run untrusted Rust snippets
• you want to share runnable Rust examples linked to Gists
• you need to compare compiler output across Rust toolchain channels

When to avoid

• you need network access from the compiled program, since the sandbox has none
• you need long-running or resource-heavy programs beyond the time and memory limits
• you need crates outside the top 100 plus Cookbook set and their dependencies
• you need persistent disk storage, which the sandbox does not limit or provide
