gathio

Gathio provides a platform for creating event pages that can be shared without requiring attendees to register. Each page can be configured to self‑destruct after a set time, ensuring that information is only available while needed. The service emphasizes privacy, avoiding the collection of personal data and keeping event details limited to the shared link.

The software is designed for self‑hosting, allowing individuals or organizations to run their own instance on any server. It is released under the GPL‑3.0 license, is free to use, and does not require a subscription. Documentation is available on a public site and in the repository’s docs folder, with instructions for installation, customization, and federation with other instances.

Because it is open‑source and federated, users can interoperate with other Gathio deployments while maintaining control over their own data. The project is marked as stable and includes a publicly hosted flagship instance for immediate use.
