Gathio is an open-source event hosting platform that provides simple, shareable event pages designed for privacy and minimal friction. Pages can be created without registration and configured to self-destruct after use, enabling ephemeral event management and invite links.

Key Features

• Create single-page event sites that require no user registration
• Shareable links for attendees and simple RSVP/attendance workflows (link-based)
• Optionally self-destruct or expire event pages after a set time
• Federated, privacy-first design to minimize data collection and increase control
• Lightweight server-rendered UI using Handlebars templates for easy customization
• Deployable with container tooling; includes Docker support for straightforward self-hosting

Use Cases

• Host ad-hoc meetups or private gatherings with shareable, time-limited pages
• Provide one-off event invitations where attendee sign-up is not desired
• Create ephemeral community or social events that should expire after use

Limitations and Considerations

• Not a full-featured calendar or ticketing platform; focuses on simple event pages rather than complex event management
• Feature set and federation interoperability may vary depending on deployment and configuration

Gathio is suited for teams and communities that need lightweight, privacy-respecting event pages without the overhead of full calendar systems. It emphasizes simplicity, ephemeral sharing, and ease of deployment for self-hosting environments.

Atria is an open-source event management and professional networking platform designed for hybrid and virtual events. It combines session scheduling, sponsor management, and attendee discovery with real-time chat to help organizers foster meaningful connections.

Key Features

• Multi-day event and session management with drag-and-drop speaker organization
• Real-time communication (session chat, backstage, direct messages) powered by Socket.IO
• Professional networking tools: icebreakers, attendee discovery by role/interests, privacy controls
• Multi-tenant architecture with granular role-based permissions and organization-level isolation
• Sponsor management with multi-tier support and automated image optimization (WebP conversion)
• Developer-friendly API surface with OpenAPI docs and a RESTful design
• Docker-first deployment and Redis-backed clustering for Socket.IO scaling
• Support for S3-compatible object storage for uploads and PostgreSQL for data persistence

Use Cases

• Hosting enterprise conferences or multi-day summits with sponsor tiers and analytics
• Running community or creator events that emphasize attendee networking and moderated chat
• Supporting hybrid workshops, fundraisers, or educational events with virtual attendance and live session chat

Limitations and Considerations

• Licensed under AGPL-3.0: modifications run on a server must be made available according to the license, which may be incompatible with some proprietary workflows
• Several planned features are on the public roadmap (custom event theming, advanced analytics, ticketing integrations, AI-enhanced tools) and may not be available yet
• Project status notes partial backend test coverage (~47% reported) and active development; production operators should review current CI/test status before large deployments

Atria is suitable for teams that want a transparent, extensible platform for events and networking. It can be self-hosted for full control or used via the project’s managed offering for a hosted experience.

Karrot is an open-source web platform designed to help grassroots initiatives and local groups coordinate face-to-face activities, manage membership and share resources. It focuses on transparent, democratic and participatory group management while providing maps, activity scheduling and contextual chat.

Key Features

• Independent groups: each group has its own settings, logo, membership rules and governance mechanisms.
• Activity scheduling with slots: create time-and-place activities (meetings, pickups, events) with sign-up slots and attendance tracking.
• Offers and local sharing: create offers for items or services and discuss interest in per-offer chats.
• Contextual messaging and notifications: group-wide messages, private messages and activity/place-specific chats; configurable notifications.
• Trust-based role system and membership review: peer-assigned trust levels, application workflow, voting and membership review tools.
• Maps and lists: map-based discovery of groups, places and participants alongside chronological lists of upcoming activities.
• Audit trail and transparency: history logs of actions for accountability and moderation.
• Extensible plugin system: frontend and backend plugin APIs for custom features and integrations; frontend uses a Vite-based build and i18n support.
• Deployment options: published Docker images, Docker Compose guides and a recommended coop cloud/ansible deployment workflow.

Use Cases

• Food-rescue and community food-sharing groups scheduling regular store pickups and coordinating volunteers.
• Local mutual-aid or neighborhood groups organizing events, tasks and resource-sharing with clear membership processes.
• Small community organizations that need lightweight, transparent tools for activity sign-ups, offers and discussion.

Karrot provides a focused toolset for local, volunteer-driven coordination with an emphasis on transparency and community governance. Its plugin architecture and published deployment guides make it adaptable for different group needs while remaining technology-agnostic and community-driven.

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.

• Group features for organizing communities and recurring activities
• Participation management: RSVP/attendance, visibility controls, and event updates
• Federation via ActivityPub to follow and interact across compatible servers
• Multi-identity support (profiles) to separate public and private participation

Use Cases

• Local communities publishing events without depending on centralized platforms
• Organizations managing meetups, workshops, and recurring group activities
• Federated event discovery and cross-instance following for public calendars

Mobilizon provides a privacy-conscious alternative for community event publishing, combining event management with federation to reach audiences beyond a single server while keeping control in the hands of administrators and communities.
