Maestro is a lightweight Unix-like kernel and operating system written from scratch in Rust, aiming for Linux syscall compatibility while leveraging Rust's type system for memory safety. It is in early-stage development, supporting x86_64 and x86 with AArch64 planned, and explicitly not production-ready.

Use cases

• run a lightweight Linux-compatible kernel written in Rust
• study how to write an OS kernel in Rust from scratch
• experiment with a POSIX-like kernel with kernel modules
• explore memory management like buddy allocators and copy-on-write in a real kernel
• follow operating system development in Rust
• test Linux syscall compatibility on a small kernel

When to choose

• you want a small, Rust-based Unix-like kernel to learn from or contribute to
• you need a Linux-compatible kernel that strips away legacy code
• you are researching memory-safe kernel design

When to avoid

• you need a production-ready OS - the project is explicitly unstable and incomplete
• you need full Linux syscall coverage - only roughly 30% is implemented
• you need AArch64 support - it is planned but not yet available
