Questions?

We’re glad you asked.

What is DualCheck?

DualCheck is a visual testing tool that helps teams compare Figma designs with live websites.

Who is DualCheck for?

DualCheck is built for developers, designers, and teams that want to make sure live pages match their designs before release.

How is this different from reviewing designs manually?

Instead of switching between Figma and the browser and comparing by eye, DualCheck lets you view both together, so that any differences become immediately visible.

Do I need technical setup to use DualCheck?

No complex setup is required. Install the Figma plugin, connect your live site, and start comparing pages.

When should DualCheck be used?

Most teams use DualCheck during QA and pre-launch review, but it can also be used during development to catch mismatches earlier.

Is DualCheck only for Webflow sites?

No. While it was built inside a Webflow agency, DualCheck works with any live website that can be compared against a Figma design.

How can I try DualCheck?

You can request early access directly from the website and start using DualCheck once your workspace is approved.
