Firefish's ActivityPub extensions

These are the extensions to ActivityPub that Firefish implements. This page uses compact IRIs. The firefish prefix is used to refer to


  • Compact IRI: firefish:speakAsCat
  • Canonical IRI:

Used on actors to indicate that they not only identify as a cat, but also want to have their text be transformed to speak like one, expressed as a boolean value. If this property is set to true, displaying the actor’s posts will make them speak with “nya” instead of “na” and other cat-related text mannerisms. Used in combination with misskey:isCat.
