Mission

ZeroDDS exists to give industrial, automotive, robotics and IoT systems a DDS implementation that is open, audit-ready and free of vendor lock-in. We implement the full OMG stack — DDS, RTPS, XTypes, Security, XML, XRCE, RPC, Java-PSM, C++-PSM — and bridge to every protocol that matters in the same codebase.

Five zeros

Zero dependencies: Foundation crates have no transitive cargo bloat.
Zero unsafe: Wherever structurally possible. Every unsafe block carries a SAFETY justification, lint-enforced.
Zero panic: Contractual Result-everywhere on the hot path.
Zero copy: Shared-memory transport (iceoryx2-compatible) for end-to-end zero-copy paths.
Zero vendor lock-in: Wire-byte-identical to Cyclone, OpenDDS, Fast DDS, RTI Connext on RTPS 2.5.
