  ## Rust Playground
  -[Rust Playground](https://github.com/integer32llc/rust-playground) allows you to experiment with Rust before you install it locally, or in any other case where you might not have the compiler available. The Rust playground can be accessed [here](https://play.rust-lang.org).

  ## Crater
  -[Crater](https://github.com/rust-lang-nursery/crater) is a tool to run experiments across the whole Rust ecosystem. Its primary purpose is to detect regressions in the Rust compiler, and it does this by building large number of crates, running their test suites and comparing the results between two versions of the Rust compiler.
