I’d spent $2,000 on a custom theme and countless hours perfecting the product pages, but the moment customers logged into their account, they saw what basically looked like a WordPress admin panel…

Introduction Removing backgrounds from images is a common need. but many solutions require uploading your image to a server. What if you could run it fully in the browser, with no backend, no API keys, and full privacy? That’s exactly what this project does.

I just spent 48 hours building a feature the user will never notice.It wasn’t a complex algorithm. It wasn’t a 3D animation. It was a “Sign in with Google” button. For the past two days, the Direct Google Sheets integration—my most requested feature—was dead on arrival. Here is the technical breakdown of why “simple” integrations…
