Free plan Linux

What balenaEngine is

balenaEngine is a free Linux container engine for embedded and IoT systems, built on Moby Project technology from Docker. It runs Docker containers, uses the Docker runtime interface and image format, and supports image building. The engine is distributed as one binary described as 3.5 times smaller than Docker CE, with support for chipset architectures ranging from small IoT devices to industrial gateways. Linux downloads are listed for amd64, armv5e, armv6l, armv7hf, and i386. Binary-diff container updates can be 10–70 times smaller than pulling layers in common situations. Layers are extracted as they arrive to reduce disk writes, while atomic, durable pulls are designed to withstand power failures. Pull behavior also aims to avoid page-cache thrashing in low-memory systems. The product page links documentation, forums, a changelog, installation instructions, and a separate download. Docker Swarm, cloud logging drivers, plugins, overlay networking drivers, and non-BoltDB-backed stores are excluded.

Who it suits

balenaEngine suits embedded and IoT deployments where bandwidth, storage, power, or memory are limited. It is for Linux environments using Docker-compatible containers.
