Pure-Rust DDS/RTPS middleware. Designed and built in France.

HDDS does not claim compliance -- it is tested for it, continuously, against every major DDS implementation in the official OMG interoperability campaigns.
- OMG DDS-RTPS campaign (continuous, snapshot of 2026-07-22): the only product at the maximum of both leaderboards -- perfect single-product score (105/105) and co-leading cross-product score (1356/1505), ahead of RTI Connext.
- OMG DDS-XTypes campaign (run of 2026-07-17): highest cross-vendor pass rate aggregated across the six report variants -- 82.5% on an identical test perimeter (CoreDX 78.6%, Cyclone DDS 77.5%, RTI Connext 71.1%) -- and 100% self-conformance (1799/1799).
- Officially registered RTPS vendor ID
{0x01, 0x1A}(DDS Foundation registry).
The OMG campaigns are continuous and results move: figures above are dated snapshots, verifiable in the public campaign reports.

| hdds_packs | Self-contained demonstration projects, from air-defense radar to smart factory. |
| HDDS Viewer | Real-time DDS observability and capture-replay desktop tool (commercial). |
| HDDS Studio | Visual IDL editor with round-trip fidelity (commercial). |
| Project | What it is |
|---|---|
| devit | Security sandbox for AI coding agents: approval engine, HMAC-signed operations, immutable audit trail. |
| aircp | Real-time multi-agent AI collaboration, powered by HDDS. |
| bitnet-arc | BitNet ternary kernels on Intel Arc GPUs. |
HDDS is developed with an AI-assisted pipeline (architecture, code review,
quality guardrails, audit campaigns, CI) -- and validated by the
interoperability results above.
