How it works

From our server to your journals

Licenses are bound to domains. Updates come from the official source — clones go stale quickly.

Install the hub

Place the Control Panel once on the customer’s OJS site.

Pull from the gallery

Crossmark, Letter of Acceptance, Workflow Dates, and other products install from the official gallery.

Activate the license

Per-domain keys are verified online; other domains or expired keys cannot run the product.

Who it’s for

Built for publishing teams

  • Campus multi-journal sites One licensing policy across many OJS contexts, with consistent updates.
  • Publishers & research offices Control plugin distribution without circulating free zip archives.
  • OJS technical teams Fewer date fixes via SQL; editorial corrections stay in the interface.
