It looks like Kittybox is close to its finish line and general protocol-compliance goal. The only unimplemented parts are:

  • In-house IndieAuth (auth and tokens)
  • Webmentions
  • WebSub pings

Then it will reach full protocol-compliance status, and I could go on to develop other things like pretty UI for posting, the Microsub server (because I really want my own!) etc.
