The platform

Five components.
31 apps. One Nextcloud workspace.

Every ConNext app plugs into one of five categories around the Nextcloud workspace, files, mail, calendar, talk, office. All of them run on the platform your team already trusts. Hover any app to see what it does.

The bigger picture

This is not an app shelf.
It is Nextcloud as a platform.

The sovereign-workplace bundles are the start, not the finish. Microsoft has spent five years training a generation of citizen developers on Power Platform; Europe has eighteen to thirty-six months to ship a credible architectural answer. Our CTO wrote down why we think the shape of that answer is already sitting in front of us.

Plays well with the workspace

Seven ecosystems, one workspace.

Conduction apps live next to the Nextcloud apps your team already uses, and call out to the workflow and AI tools you bring with you. Click a row to see how the integration shows up.

Pin a Conduction sidebar to any email or file. See every case, register row, or document linked to the item. Jump to it without leaving the thread.

External tools we integrate

Open source we use, not own.

Most Conduction integrations are with the standard Nextcloud apps already on the home screen, Mail, Files, Calendar, Contacts, Notes, Deck. The set below is different. These are external open-source projects we did not build. We host them next to Nextcloud as ExApps (separate processes the workspace runs and exposes through its UI), or call them through OpenConnector adapters. Reusing them is cheaper than rewriting them, and it keeps the credit where it belongs.
