How to Be Sure Your Development and Design Team Is Actually in Sync
You’ve probably experienced this before: a developer ships a page, a designer opens the live site, and within seconds starts pointing out things that don’t match.
It can be small details like a button color that’s not exact, spacing that’s just a little off, or typography that doesn’t match perfectly. Small differences like these add up and end up costing more time to correct than they ever should.
There’s a simple way to avoid this kind of back-and-forth, and it starts with using the right visual testing tools during review.
Why Comparing Designs Is Harder Than It Needs To Be
The disconnect between design and development happens because comparing a Figma file to a live website is genuinely awkward. You're tabbing between two windows, zooming in and out, trying to hold a mental image of one while you look at the other.
Without a structured way to spot and report differences, things slip through. A developer might think something looks close enough, while a designer can tell it’s slightly off but isn’t sure how to flag it without starting another round of back-and-forth in Slack
By the time the issue is communicated, tracked, and fixed, it's taken three times longer than it should have.
The other common problem is the lack of clarity around review status. Is this page approved, does it need changes, or is it still waiting to be checked?
Having a built-in way to mark and update page status keeps the entire team aligned without extra messages.
Introducing: DualCheck
DualCheck is a visual regression testing tool that puts the comparison directly in front of you. It overlays your Figma design against the live website with a slider, so anything that doesn't match becomes immediately visible.
There's no tab-switching. You're looking at both at the same time, and the differences are obvious.
Once you've spotted something, you can leave a comment directly on that section of the page.
The comment stays tied to the exact area you're reviewing, so there's no ambiguity about what you're referring to. Developers know precisely what needs to change, and the conversation lives in context rather than scattered across chat threads.
Each page also has a status that the team can set and update: Draft, Ready for Review, Needs Changes, or Approved, and everyone can see where things stand without having to ask. When a page is approved, it's approved. When something needs to be fixed, it's marked accordingly, and the developer knows to go back to it.
All of this is visible in a project board that shows every page across your projects and where each one sits in the review process.
Who DualCheck Is For
Running several projects at once makes it harder to see where things stand.
Agencies, for example, need visibility across several client builds at the same time. Knowing which pages are finished, which are still in review, and which have unresolved comments shouldn’t require digging through threads or asking around.
DualCheck is also useful for in-house teams, where review feedback tends to pile up near launch, and small visual fixes can easily get lost in informal messages. Instead of screenshots with circles drawn on them, comments live directly on the page, and the page status shows whether it’s approved or still needs changes.
Regardless of team size, having a shared reference point changes how review feels since designers and developers are no longer working from scattered tools.
The Figma file remains the design reference while the live site shows the implementation. DualCheck makes it easy to compare the two, flag differences, and resolve them in one place.
