`openrsync` is a BSD-licensed implementation of `rsync`, maintained by OpenBSD developer Kristaps Dzonsons and merged into the OpenBSD base system.
The project targets compatibility with modern `rsync`; the repository says testing uses `rsync 3.1.3`, and any peer that supports protocol `27` should work.
The implementation supports only a subset of `rsync` command-line arguments rather than full flag parity with the upstream tool.
OpenBSD is the officially supported OS, but the repository includes portability glue so it can compile and run on other Unix systems.
Canonical documentation is provided through the manual pages `openrsync(1)`, `rsync(5)`, and `rsyncd(5)`, with protocol details intended to be sufficient for other implementations.
The repository states that development originated as part of the `rpki-client` project, an RPKI validator for OpenBSD.
Funding credits listed in the README include NetNod, IIS.SE, SUNET, and 6connect.
Installation on an up-to-date Unix system is documented as `./configure`, `make`, and `make install`, and the project says it can coexist with an existing `rsync` install without file collisions.
