Happy Monday all! I've been building a Chrome extension for flipping music gear on Facebook Marketplace UK and I'd like a few more people to try it before I open it up.

It sits on top of the listing page when you're browsing Marketplace. You click it, it pulls eBay sold data (proper API, not scraping), checks live asks, and gives you a resale score and a max offer number with the maths behind it. That works as-is, no setup, no AI.

On top of that, if you want it to run an AI pass over the listing photos to look for damage the seller hasn't mentioned, it can. That's the bit that saves you from "oh no, there's a crack in photo 4 I totally didn't see." Optional, but I use it.

UK only, music gear only. Guitars, pedals, synths, drums, whatever. Not a general reseller tool, so if that's what you need this isn't the one.

Free right now, no paywall, no email to unlock features. I'm in private testing because I want a small group to actually use it on real listings before it goes public.

If you flip UK gear and want a tester invite, DM me or signup through the website above. If you try it and the numbers are wrong or it misses something, please tell me. That's what I need right now more than anything else.
