I built SimuLovice because I was honestly tired of the daily friction in my own workflow. As a developer, every time I wanted to show a quick update to a client or grab a clean screenshot for my portfolio, it was a hassle. I had to jump between browser DevTools, screen recorders, and design apps just to make a live website look decent. So, I decided to build a tool that does all of that in one place. With SimuLovice, you can test how your code behaves on different devices, throw a nice background behind it to create a quick mockup, or record a video demo in just a few clicks. No extra tabs, no complications, and it runs completely locally so your work stays private. This is a big step for the project, and I’d love to know what you think. What features are you missing in your current setup? Any feedback or questions are more than welcome! Thanks for checking it out today!
