RIOT is an open-source, vendor-independent operating system for Internet of Things and embedded devices, supporting 8/16/32-bit microcontrollers across 200+ boards. It emphasizes energy efficiency, real-time capabilities, small memory footprint, and a uniform, partially POSIX-compliant API with standard C/C++/Rust tooling.

Use cases

• build firmware for low-power IoT sensor nodes
• develop applications for ESP32 or ARM Cortex-M microcontrollers
• run a real-time OS on constrained embedded hardware
• prototype IoT networking with 802.15.4 and 6LoWPAN
• write portable code across 8-bit, 16-bit, and 32-bit MCUs
• implement secure firmware updates for IoT devices
• run an IoT OS natively on Linux or BSD for testing

When to choose

• you need a real-time, energy-efficient OS for microcontroller-based IoT devices
• you want hardware-independent code that runs across many MCU architectures and boards
• you value open standards, security features like DTLS and SUIT, and a vendor-neutral community
• you want to program embedded devices with standard gcc/gdb tooling and partial POSIX APIs

When to avoid

• you need a full general-purpose OS with rich userspace like Linux for powerful hardware
• your project targets only high-level platforms (web, mobile, desktop) with no embedded component
• you require a commercial RTOS with vendor certification and support contracts
• you need heavy multithreading or large memory footprints beyond microcontroller constraints
