Hey Product Hunt, I built seeonwall.com after trying to buy a poster for my living room and hitting a wall - no shop had a decent preview tool. It was either AR (barely works, even on newer phones) or static mockups that don't match your actual room. Worst part: no sessions. Every preview meant re-uploading a photo of my wall, so comparing posters side by side was basically impossible. So I built what I wished existed: upload your wall once, then drop in as many posters as you want - true-to-scale, in the browser, no app needed. It's also privacy-first (no tracking cookies, EU-hosted, photos delete themselves), and merchants can add it via Shopify, WooCommerce, or a simple script tag. Hop over to the live demo to see how the preview and sessions actually work. It's live and free to try. If you run a poster/print shop, I'd love feedback on embedding it - and if you've just been annoyed by bad mockups like I was, try it on your own wall!
