Hey, I made this quick tool that allows you to find interesting Facebook groups. Insert a keyword to search, filter, sort, and export results in plain text and CSV formats.

You can also scan groups to quickly analyze how fast they are growing, and how engaged the community is.

Here is a list of Fb groups that are growing fast: https://targetsnake.com/top-groups

It's totally free and I'm sure buggy (I made this in 12 hours), but hopefully useful!

Best, Mike
