FediThreat is open source, and self-hostable, allowing you or your organization to configure your Pixelfed server to query your custom FediThreat server.
It will also support auto registration using http signatures, so you don't have to sign-up for an API key.
Just press a button in the admin dashboard to enable it ✨
Last but not least, it will support other platforms aside from Pixelfed using a simple, yet powerful REST API.
