Pixelay is a Figma plugin and Chrome extension by Hypermatic that overlays Figma frames on live web pages for visual comparison. It's one of the most established tools in the category, with over 70 versions since 2020. But it's one approach to a problem that can be solved in different ways. Here's what else is available.
The most common reasons to look beyond Pixelay are workflow friction and output format. Pixelay's overlay approach requires exporting a design frame, positioning it in the browser, and toggling opacity to spot differences. The comparison is visual and manual. There's no structured output, no list of specific differences, and no way to share a report with someone who wasn't looking at the screen.
For individual developers checking their own work, this is often fine. For teams that need to communicate findings across designers, developers, and QA engineers, the lack of structured output creates friction.
Approach: Overlay comparison via Chrome extension. How it works: Upload a screenshot of the design, overlay it on the live page, adjust opacity and position to compare by eye. Purely manual. Pricing: Free (2 layers) + Pro at $25/year.
PerfectPixel is the original overlay tool, with over 350,000 Chrome Web Store installs since 2012. It doesn't connect to Figma directly. You export an image from Figma, upload it to the extension, and position it manually. The comparison is entirely visual.
The free tier was recently limited to 2 overlay layers, which pushed some users toward alternatives. PerfectPixel works well for quick checks on individual pages. It's less suited for repeatable QA across multiple pages or versions because every comparison requires manual positioning from scratch.
Approach: Property-level comparison (spec-based). How it works: Connect a Figma frame and a webpage URL. The tool reads properties from both sides and reports specific differences in spacing, typography, colours, and dimensions. Pricing: Free tier available. Pro plans for teams.
Uiprobe takes a different approach from overlay tools. Instead of comparing how the page looks, it compares what the page is made of. It reads spacing values, font properties, colours, and dimensions directly from the Figma file and the live page's computed styles, then reports where they differ with exact values.
The output is a list of findings, each with the property name, the design value, and the implementation value. No screenshots, no manual positioning. The comparison is repeatable: re-run it after making fixes and see what changed. Results can be shared via a public link or exported to CSV.
The Chrome Extension handles pages that aren't publicly accessible, including localhost, staging environments behind login, and password-protected pages.
Approach: Overlay comparison via Figma plugin. How it works: Directly overlays Figma frames on live pages within the Figma interface using screenshots captured from the browser. Pricing: Free tier available.
Over.fig is a Figma plugin that captures a screenshot of a live page and overlays it with the Figma frame inside Figma itself. This keeps the comparison within the design tool rather than in the browser.
The advantage is that designers can check implementation without leaving Figma. The limitation is the same as any overlay: the comparison is visual and the output is a screenshot overlay, not a structured report.
Approach: Hybrid. Overlay comparison with AI-assisted diff scoring. How it works: Chrome extension that overlays Figma frames on live pages, then runs a GPT-4o analysis to score visual similarity and categorize differences. Pricing: Freelancer $39/month, Starter $79/month, Pro $249/month. No free tier.
OverlayQA adds AI analysis on top of the overlay approach. After positioning the overlay, it runs a visual diff through GPT-4o and returns a similarity score (0-100) with categorized findings. It also includes accessibility auditing and bug capture workflows.
The AI layer addresses the "what's actually different" question that pure overlay tools leave to the user. The trade-off is pricing: there's no free tier, and the entry point is $39/month.
Approach: Visual regression testing (pixel-based). How it works: Captures screenshots and compares them against baselines using AI-powered visual diffing. Integrated into CI/CD pipelines. Pricing: Enterprise pricing.
Applitools is a visual regression testing platform, not a Figma comparison tool. It compares screenshots of a page across builds, browsers, and viewports. The use case is different: "did this page change since the last deploy" rather than "does this page reflect the Figma design."
It's included here because it appears in search results for design QA tools, but it serves a different workflow. Applitools is strongest in automated testing pipelines where the baseline is a previous version of the same page, not a Figma design.
Pixelay uses overlay comparison via a Figma plugin. No structured output or shareable reports. No localhost support. Free tier available.
PerfectPixel uses overlay comparison via Chrome extension with manual image upload (no direct Figma connection). No structured output or shareable reports. Supports localhost. Free tier with limitations.
Uiprobe uses property-level comparison with a direct Figma API connection. Structured findings list with shareable public links and CSV export. Supports localhost via the Chrome Extension. Free tier available.
Over.fig uses overlay comparison via a Figma plugin. No structured output or shareable reports. No localhost support. Free tier available.
OverlayQA uses overlay comparison with AI-assisted diff scoring via a Chrome extension. Structured AI report with Jira export. Supports localhost. No free tier ($39/month entry).
Applitools uses pixel-based visual regression testing integrated into CI/CD. Structured diff reports. Localhost support via CI pipelines. Enterprise pricing, no free tier.
For quick visual checks during solo development, Pixelay and PerfectPixel do the job. The overhead is low and the output is immediate. If you already have Pixelay installed and it works for you, there may not be a reason to switch.
For teams that need to share findings, track changes across versions, or integrate design QA into a review process, a tool with structured output is more practical. The question becomes whether you want property-level precision (Uiprobe) or AI-scored visual similarity (OverlayQA).
For automated regression testing in CI/CD, Applitools is the established option. It's solving a different problem than Figma-to-live comparison, but it handles visual change detection at scale.
The right tool depends on the question. "Does this look right" is an overlay question. "What specifically is different from the Figma design" is a property comparison question. "Did anything break since the last deploy" is a regression testing question.
