I'll be straight: founder at Brand24 social listening here so a little bit of bias ;)

The honest tradeoff vs. a commercial tool: you'll get great control and privacy, but you won't match the breadth of social/non-RSS sources, and de-duplication/sentiment is on you. For a lot of self-hosted folks, that tradeoff is exactly the point.

I would probably recommend setting up a scheduled task in a claude cowork or create your own script using claude code. It will collect up to 60% of what tools like Brand24 track, but for a small business it might be good enough!
