Ariel OS is a library operating system for secure, memory-safe, low-power IoT devices, written in Rust and targeting 32-bit microcontrollers (Cortex-M, RISC-V, Xtensa). It integrates existing Embedded Rust crates like Embassy and esp-hal with OS-level features such as a preemptive multicore scheduler, portable peripheral APIs, and the laze meta-build system.

Use cases

• build a memory-safe IoT firmware in Rust
• run a preemptive multicore scheduler on a microcontroller
• write portable embedded applications across Cortex-M, RISC-V, and Xtensa
• secure low-power IoT networking on microcontrollers
• replace C-based RTOSes like RIOT or Zephyr with Rust
• get a batteries-included embedded Rust development experience

When to choose

• you want a Rust-native, memory-safe OS for low-power IoT devices
• you need portable peripheral APIs and multicore scheduling across microcontroller architectures
• you prefer an integrated, batteries-included alternative to assembling embedded crates yourself

When to avoid

• you need a mature, production-hardened RTOS with long-term support
• your target hardware is not a supported 32-bit microcontroller
• you work in C or need C SDK compatibility
