It was asked a couple of months ago, but given the AI enshittification, it seems a good time to ask again.
I looked around and found:
- Pinetta is/was in development but seems dead with only an alpha release. I am chasing this up on Matrix. edit: Apparently still, technically, active although progress has been slow
- Pinry is a FOSS alternative, but not federated, that seems dormant. However, it works and is in Python, so someone could bolt an AP server to it, he says airily.
I’ve used mostly for Art references when I’m drawing because the image search is mostly accurate for my needs, but now it is filled with Ai slop without a clear way to filter content, so it has became unusable for the past 3 years or so.
