QA of the live website/app against the Figma designs after developer deployment

Hi fellow designers and developers!

I'm looking for the best tool (AI-powered or a working plugin) for design QA after developers deploy a website or app based on Figma designs.

I'm looking for something that can compare the live product against the original Figma designs down to the pixel level: margins, padding, colors, typography, graphics, spacing, and everything in between.

The goal is to reduce manual QA time and avoid spending hours hunting for missing pixels or visual inconsistencies.

Ideally, the tool would scan both the live website/app and the Figma file, automatically identify discrepancies, and generate clear, actionable comments that developers can use to fix issues and match the original design as closely as possible.

I've looked into several options so far, but haven't found anything that does this efficiently and accurately.

What tools are you using? What actually works for you?

I'd really appreciate your recommendations and real-world experience!

Thanks!
