Eclipse iceoryx is a C++ inter-process communication (IPC) middleware that provides true zero-copy data transfer via shared memory, with publish-subscribe and request-response APIs. It originated in the automotive industry for high-volume sensor data exchange and is used in robotics (ROS2) and other data-intensive systems.

Use cases

• transfer large sensor data like camera or lidar streams between processes with zero copies
• build low-latency publish-subscribe communication between processes on Linux
• integrate zero-copy IPC into ROS2 or CycloneDDS-based systems
• implement request-response communication between processes using shared memory
• reduce CPU overhead and latency in automated driving or robotics middleware
• share data between processes deterministically for real-time systems

When to choose

• you need true zero-copy, shared-memory IPC with deterministic latency in C++
• you are on Linux, macOS, QNX, FreeBSD, or Windows and need high-throughput pub/sub between processes
• you are integrating with ROS2 or DDS-based automotive/robotics stacks

When to avoid

• you are starting a new project - the maintainers recommend iceoryx2, since iceoryx classic is in maintenance mode and will reach end of life after iceoryx2 v1.0
• you need network communication across machines rather than inter-process communication on one host
• you need a language other than C++ without bindings
