Our verdict on Clubnetz

Clubnetz is a free, open-source management system for tennis clubs and other sports clubs, particularly small clubs that want control over their own deployment. Members can reserve courts, arrange matches, register for events and receive club updates. Administrators can manage member records and roles, season enrollment, fee plans, court rules, tournaments, accounting and invoices. The interface is available in English and German, and the project is licensed under AGPL-3.0.

Its scope reaches beyond court reservations: booking rules include quotas, recurring bookings and court blockings, while clubs can sell court time to non-members. The calendar supports event registration and tournament planning, and membership fees can be paid online by card or SEPA. Communications include member news, announcements and push or email notifications. Accounting tools include bank statement imports and invoices; clubhouse tabs support SumUp payments. API keys provide a way to connect club tools and scripts. Lesson scheduling is not part of the described feature set, so clubs that need to organize coaching schedules should look elsewhere or assess a separate tool.

Clubs can use the hosted service free for clubs and members, or self-host Clubnetz with Docker. The available platforms include web, iOS, Android and API, with cloud and self-hosted deployment options. Stripe and SumUp are the named integrations, covering online payments and clubhouse tabs respectively. Support is listed through email and documentation, and GDPR is the stated compliance posture. Clubnetz is a fit for smaller clubs seeking a broad open-source system and willing to manage a self-hosted installation if desired; it is less suitable when lesson scheduling is central or a club needs integrations beyond those named.
