Four focused Nextcloud apps.
Every app is small, opinionated, and built on the same principles: server-side correctness, accessibility, and zero data leaks. Pick what you need — they install side-by-side and stay out of each other's way.

Free to install. Paid to fit your business.
The apps cost nothing to use — we make a living when organisations hire us to fit them to their needs. We offer consulting and requirements engineering, customise the apps (custom fields, roles, exports, integrations), build entire bespoke Nextcloud modules, and ship sponsored features straight onto the public roadmap. You can also fund ongoing open development via GitHub Sponsors.
