Ten self-hosted applications for your Nextcloud.
Each app fulfils a defined task in your instance: server-side checks, role-based permissions, data in your database. Web apps with no licence fee. Use one module, or combine them — your Nextcloud, your data. Companion apps and Check Partner are separate building blocks — prices on the detail pages and under Order or Support.
