  4. wordpress-activitypub

    Project mention: Introduction to Bluesky's at Protocol | news.ycombinator.com | 2025-08-20

    What do you mean? WordPress already supports ActivityPub through their plugin:

    https://wordpress.org/plugins/activitypub/

    I follow a few blogs on Mastodon just fine (for example John Carlos Baez's Azimuth, https://johncarlosbaez.wordpress.com/), it's just like an RSS reader in your timeline.

  5. social

    🎉 Social can be used for work, or to connect to the fediverse!

  6. loops-server

    The federated short video sharing platform.

    Project mention: Loops is a federated, open-source TikTok | news.ycombinator.com | 2026-02-22

    https://github.com/joinloops/loops-server/blob/main/INSTALLA...

    Looks like an amalgam of php, node, mysql, redis and an AWS S3-compatible filesystem.
