Currently, it supports user registration/approvals and content report management. I offer it either as a hosted app (which is currently only compatible with Lemmy 0.18 instances) or a package that you can run alongside your Lemmy instance (using Docker-Compose)
Edit for a note: This tool does not save, proxy or store any of your user credentials or data to me, it is only ever stored locally in your browser. I also do not use any website tracking tools. 👍
