Access to the tool has to be granted by Bellingcat's Auto Archiver team. We only provide access to open source researchers, journalists, or other groups or individuals aligned with Bellingcat's goals. Still, we can only provide a limited quota per user.
Do know that you can deploy your own version of this tool by hosting the API and the UI, all our code is free and open source under an MIT license.
You can always just run Bellingcat's Auto Archiver locally via the command line to achieve similar results.
