Gancio is a shared agenda designed for local communities to publish and discover events without centering personal profiles or engagement mechanics. It focuses on small, autonomous nodes and broad interoperability so events can be followed and reused across the web.

Key Features

• Shared public event listing with a content-first approach (no personal timelines)
• Privacy-oriented publishing model, including anonymous event submission by default
• Multiple export formats for syndication and reuse, including RSS feeds and iCalendar (ICS)
• Embeddable event lists or single events for external websites
• Federation support via ActivityPub to share events across instances
• Structured data support (microdata/microformats) for better interoperability

Use Cases

• Community groups running a local events calendar for a city or neighborhood
• Activist or mutual-aid networks needing low-profile event publishing and sharing
• Organizations embedding a unified event feed across multiple sites and channels

Limitations and Considerations

• Gancio 2.0 is an in-progress rewrite and was announced as alpha with incompatibilities; upgrading production instances may require caution

Gancio is a strong fit for communities that want a calendar that prioritizes shared information over user identities and growth mechanics. Its federation and export options make it easy to distribute events beyond the web UI while keeping control in local hands.
