Hubzilla

Hubzilla is a multi-purpose federated platform for building interconnected community sites. It combines social networking, collaboration, publishing, and cloud-style file sharing around a powerful permissions and identity system.

Key Features

• Fine-grained privacy and access control for posts, pages, wikis, images, and files
• Federated social networking via ActivityPub and other federation protocols
• Groups and discussion forums, including moderated communities and conversation tools
• Built-in file storage and sharing with permissioned access
• Publishing tools such as blog posts, pages, and wiki content with Markdown support
• Nomadic identity with cloning and portable identity backups across servers
• Federated single sign-on to authenticate on compatible remote hubs
• Content filtering and safety controls to reduce unwanted or offensive content

Use Cases

• Run a private community hub with controlled membership, groups, and discussions
• Host a federated social presence that can interact with the wider Fediverse
• Share files and collaborate on pages or wikis with per-user/per-group permissions

Hubzilla is well-suited for organizations or communities that need federation plus strong privacy controls and portable identity. Its all-in-one approach makes it a flexible “home base” for social interaction and collaboration.
