    About the Online Rust Compiler

    The Mentrily online Rust compiler lets you write, compile, and run Rust code directly in your browser. Your program executes in a secure cloud sandbox with standard input support, so it behaves the same way it would in a local terminal — without installing a compiler, IDE, or toolchain.

    It is perfect for practicing Rust, testing snippets, preparing for coding interviews, and classroom use. Start typing and hit Run — no account required.

    • Compile and run Rust in a secure cloud sandbox
    • Standard input (stdin) support for interactive programs
    • Fast editor with syntax highlighting and error output
    • Free to use, no account required to start
    • Switch between 30+ programming languages instantly

    Frequently asked questions

    Is this online Rust compiler free?

    Yes. The Mentrily Rust compiler is completely free. You can write, compile, and run Rust code online without creating an account or installing anything.

    Do I need to install Rust on my computer?

    No. Your Rust code is compiled and executed in a secure cloud sandbox, so it works on any device with a browser — laptops, Chromebooks, and tablets included.

    Can my Rust program read input (stdin)?

    Yes. The playground supports standard input, so programs that read from stdin work the same way they would in a local terminal.

    Can I save or share my Rust code?

    Yes. Create a free Mentrily account to keep your work, or use the built-in question builder to turn a snippet into a shareable practice problem.

    Can I use this Rust playground for teaching or exams?

    Yes. Mentrily is a full teaching platform — educators can build courses and proctored exams with auto-graded Rust coding questions, then track learner progress in one dashboard.
