Embedded is one of the fastest-growing homes for Rust — because memory safety matters most on devices you can't easily patch. We build reliable, memory-safe firmware and IoT systems in Rust, from bare-metal microcontrollers to Linux-class edge gateways.
no_std Rust on microcontrollers (ARM Cortex-M, RISC-V, ESP32) with HALs and the Embassy / RTIC ecosystems.
BLE, Wi-Fi, MQTT and LoRa device stacks; secure provisioning and OTA update paths.
Linux-class edge devices bridging sensors to the cloud, with efficient async networking.
Memory safety without a GC is decisive in healthcare, industrial and automotive contexts.
Minimal footprint and deterministic timing on constrained hardware — no runtime, no surprises.
Drop Rust into existing C firmware via FFI — replace the riskiest modules first.
On a device in the field, a memory-safety bug isn't a server you restart — it's a recall, a security breach, or a safety incident. Rust brings compile-time memory and concurrency safety to embedded without a garbage collector and without a runtime, so you get C-level control and footprint with far fewer of C's catastrophic failure modes.
The ecosystem is production-ready: no_std for bare metal, mature HALs for popular chips, and async frameworks like Embassy and RTIC for concurrent firmware. We build new devices in Rust or migrate the critical pieces of existing C firmware incrementally over FFI.
Yes, and adoption is growing fast. Rust runs on bare metal via no_std, has mature HALs for common microcontrollers, and gives memory safety without a garbage collector — ideal for devices where a bug is expensive to fix in the field.
no_std tells Rust not to use the standard library that assumes an operating system, so your code can run directly on a microcontroller with no OS. You still get the core language, safety guarantees and a rich embedded crate ecosystem.
ARM Cortex-M and RISC-V families, ESP32, and Linux-class edge boards, among others, using the Embassy and RTIC ecosystems and device HALs.
Rust matches C on performance and footprint while eliminating whole classes of memory bugs at compile time. For new or safety-critical firmware it's increasingly the better default; existing C can be migrated module by module.
