## What it is
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

## Facets
- artifact type: library
- maturity: experimental
- function: embedded, networking, security, concurrency, build-tool
- domain: iot, embedded-systems, operating-systems, security
- platform: embedded, iot, rust, cross-platform
- tags: rtos, library-os, microcontroller, memory-safe, low-power, embassy, multicore-scheduler, cortex-m, risc-v, xtensa
