monity.ai - set a URL and a prompt to get alerted on changes (price drops, restocks, or competitor updates). Built to replace messy browser extensions and custom scrapers.

This is the first place I've posted it but I just created https://friendssale.com/

I don't know if it qualifies as micro-SaaS. I'm moving and I created it to essentially list items for my friends to bid on so I don't have to put stuff on FB marketplace or ebay and deal with tire kickers. I'd rather sell to friends and family.

Edit: Disclosure, it was AI coded.
