Known is an open-source social publishing platform that lets individuals or groups publish posts, notes, photos, and other media to a site you own. It emphasizes IndieWeb compatibility and multi-user collaboration, with a simple, responsive interface.

Key Features

  • Bookmarklet: Easily post to your site, save links, and respond to comments from any page on the web
  • #Tags: Use hashtags to categorize content
  • Responsive Layout: View, edit, and post to your site from any device
  • Decentralized Indieweb: Sites can respond to each other, bookmark each other's content, and leave comments
  • Email Notifications: Get updates whenever someone responds to a post
  • Feeds: Access updates via RSS, XML, JSON, or KML
  • Multi-Author: Invite an unlimited number of collaborators
  • HTML & Rich Text Editor: Write in HTML or use a WYSIWYG editor
  • Custom URL: Bring your own domain to own your site
  • Static Pages: Create static pages like about or contact
  • Privacy: Private spaces and access controls
  • Custom JavaScript & CSS: Extend the site with custom scripts and styles

Use Cases

  • Personal or multi-user sites for publishing posts, photos, and media with open syndication across Indieweb networks
  • Education: classroom spaces and course projects with LTI integration and data ownership
  • Community sites and collaborative spaces where multiple authors publish and discuss content

Limitations and Considerations

  • This section intentionally omitted as there are no major Known-specific limitations highlighted here; refer to official documentation for deployment considerations when self-hosting.

Conclusion

Known provides a self-hosted, open-source publishing platform that supports multi-user collaboration, Indieweb interoperability, and ownership of content, suitable for personal sites, classrooms, and communities.
