Nextcloud Apps · 100% self-hosted
Run the tools your team needs — inside your own Nextcloud.
Time tracking, duty rosters, project work, and budgets: four focused apps that turn your Nextcloud into a workplace your team actually uses — without sending data to anyone else's cloud.

- WCAG 2.1 AA targeted
Free to install. Paid to fit your business. Use the apps free of charge — and hire us when you need consulting, requirements engineering, or custom Nextcloud development to make them work exactly the way your organisation does.
