I got mass-rejected from mockup generators, so I built my own
I sell POD stuff on Etsy. Wall art, mostly. Every time I finished a new design, I had to place it into a poster frame mockup in Photoshop. Then a different frame. Then a t-shirt. Then a mug. Each one is its own file, its own export, its own "Save As" dance.
Last month I had 20 new designs and 6 templates. That's 120 mockups. I timed it once. Took me the better part of 4 hours. For listing photos.
I tried Placeit and Smartmockups (RIP). They're fine for one-off mockups, but neither lets you do more than one at a time. Same clicking, just in a browser instead of Photoshop.
So I built Scaylr. It does one thing: you upload PSD templates, upload your designs, and it spits out every combination as a ZIP. 20 designs, 6 templates, 120 mockups. One click. The ZIP is sorted by design name so you can drag folders straight into your Etsy listings.
It runs on Cloudflare Workers with Photopea handling the PSD rendering. The whole backend is a single worker.js file. No React, no Next, no frameworks. Vanilla JS. D1 for the database, R2 for storage, Stripe for billing. Total infrastructure cost while building: $0.
Pricing is simple. Free gets you 30 mockups a day with watermarks. $9.99/mo for 1,000 mockups without watermarks. $17.99/mo for unlimited.
I don't have a huge roadmap. Right now I'm adding more templates to the free library and writing comparison posts that rank for "best mockup generator for Etsy" type searches. SEO is basically my entire growth strategy since my audience (Etsy sellers) actively searches for this stuff.
If you sell on Etsy or do POD, I'd be curious what your mockup workflow looks like. Are you still doing them manually? Using something else?
