Veynode is designed around the handoff between building a website and making that website live. A developer needs a way to inspect the exact output, share a review URL, and know which version currently receives production traffic.
When preview and publication are treated as one event, a build can become a release before anyone has checked it. Veynode gives those steps separate records and actions: a build creates a candidate, a deployment provides a reviewable preview, and an explicit publish operation changes the stable project route.
The same separation informs rollback. Returning to a previous version means selecting an already-ready deployment and changing the route, rather than rerunning old source and hoping the new build behaves identically.
