HDDS is developed by a team with 25+ years of experience in real-time systems, defense middleware, and embedded software.
European defense and aerospace need DDS implementations they can audit, modify, and trust.
Existing solutions are either proprietary (RTI, CoreDX) with opaque code and US export controls, or open-source but lacking the quality rigor required for certification (DO-178C, ISO 26262, ANSSI).
HDDS fills this gap: a pure Rust implementation with industrial-grade code quality, 19-layer audit scanner, and full interoperability with existing DDS vendors.
DDS/RTPS protocol expertise from real defense programs. RTI Connext interoperability testing. ANSSI/IGI-1300 awareness.
25+ years in embedded systems, real-time middleware, and high-performance networking. From 8-bit MCUs to distributed systems.
Early Rust adopter. no_std embedded, async runtime internals, unsafe auditing, memory-safe systems programming.
Based in France. No US export restrictions. Full source code access. European data sovereignty.
The DDS implementation is 100% open source (Apache 2.0 / MIT). No "open core" tricks. Audit it, fork it, deploy it.
We ship less, but what we ship passes 19 audit layers, Valgrind, ASan/TSan/MSan, and continuous fuzzing.
HDDS works with your existing DDS infrastructure. RTI, FastDDS, CycloneDDS - we test against all of them.
No enterprise tier, no feature gates, no "contact sales". TSN, security, cloud discovery - all included. cargo add hdds
