Hitobito is open-source software for managing associations, federations and other community organisations, such as youth organisations, music and sports clubs and political parties. It manages contacts and members with roles and permissions, can model federal and distributed organisation structures precisely, handles course and event registration digitally, and includes a mailing system plus invoicing and payments, including EBICS. It is modular and can be extended with custom modules. You can download and run it yourself, use it as a cloud service, or have it adapted to your needs.
Hitobito AG is based in Bern, Switzerland, and presents itself as a solution of Puzzle ITC AG. The source code is published on GitHub under the AGPL-3.0, so self-hosting without licence fees is possible. According to the vendor, the cloud service runs on a Swiss container platform. Its privacy statement is based on the GDPR. No foreign owner is named. Switzerland is not an EU member but an EFTA country with an EU adequacy decision.
