VLink

VLink is a high-performance C++ communication framework designed for autonomous driving and robotics applications. It provides a unified API across multiple transport backends (intra-process, shared memory, DDS, SOME/IP, MQTT, Zenoh, and others), supporting three communication models: Event (publish/subscribe), Method (request/response), and Field (state synchronization). The project includes 15 serialization formats, 10 CLI tools, record/replay capabilities, and visualization bridges for Foxglove and Rerun.

The framework targets developers building systems that need to switch between different communication backends without changing application logic. It supports Linux, macOS, Windows, QNX, and Android on x86_64 and ARM64 architectures. The repository describes VLink as a full-scenario alternative to ROS 2, offering compile-time serialization selection, lock-free queues, and zero-copy paths for performance-critical deployments.
