OverlayQA helps design and frontend teams catch visual bugs before users do.
Compare your Figma designs against any live page, run AI-powered design reviews, and audit for WCAG accessibility issues, all from your browser.
How it works: - Connect your Figma account and select a design frame - Navigate to any URL: localhost, staging, or production - Toggle the overlay to spot visual differences instantly - Run an AI Design Review or Accessibility Audit in one click - Export issues with screenshots, CSS selectors, and metadata to Jira, Linear, Notion, or Slack
Key features: - Visual Comparison with opacity controls and responsive scaling - AI-powered design review that flags layout, spacing, and typography issues - WCAG accessibility auditing with axe-core and AI analysis - Two-way sync with Jira, Linear, Notion, and Slack - Shareable issue links for client and stakeholder review - Works on any URL: localhost, staging, or production reviews, and audit for WCAG accessibility issues, all from your browser.
Most teams still check design implementation by eye. Flicking between Figma and the browser, taking screenshots, leaving comments. It is an annoying, draining time sink that pulls focus from real work.
We built Uiprobe to take that off your plate. You give us a Figma frame and a live URL, and we compare them by reading the computed CSS of the rendered page rather than overlaying images. We surface the exact differences in spacing, color, typography, and size as structured findings, each with its expected and actual values.
The comparison is deterministic. Run the same probe twice and you get the same findings. That reliability is the whole point: AI tools generate the code, and we verify the output against the design.
Findings are organized into three sections so you can scan what diverged and act on it:
Re-run a probe after a fix to see the delta against the previous version. Uiprobe runs as a web app, a Chrome extension, and a Figma plugin.

UiprobeOverlayQA's answer
OverlayQA is the only design QA tool that combines Figma overlay comparison, AI-powered design review, and WCAG accessibility auditing in a single Chrome extension. Every issue captured includes the CSS selector, computed style values, page metadata, and a screenshot, so developers get dev-ready bug reports instead of vague feedback. It works on any URL: staging, localhost, or production.
Uiprobe's answer:
We compare your Figma design against the live page deterministically, reading the rendered page's computed CSS rather than overlaying screenshots. Run the same probe twice and you get the same findings. The output is a structured list across three sections, Properties, Spacing, and Unverified, each with the exact expected and actual values, so you see the precise property that diverged instead of a fuzzy image diff.
OverlayQA's answer
Most visual bug tracking tools capture a screenshot and stop there. OverlayQA captures the CSS selector, computed values, viewport, browser info, and a link to the original Figma frame in every issue. It exports directly to Jira, Linear, and Notion with one click. The AI design review uses GPT-4o to flag layout, spacing, and typography issues automatically. No other tool in this category combines visual comparison, AI review, and accessibility auditing.
Uiprobe's answer:
Reliability. We deliberately kept AI out of the detection path, because AI-based comparison gave different results between runs, and if you run the same comparison twice and get different answers, nothing else matters. Reading computed CSS instead of comparing images means a finding names the exact property and value that diverged. For teams shipping front-ends from Figma, that means less manual pixel-peeping and fewer back-and-forths in review.
OverlayQA's answer
Design and frontend teams at product companies (50-500 employees) who use Figma and need to verify that what shipped matches the design spec. Also agencies and studios who need to QA client sites before handoff. QA engineers, designers, and frontend developers all use it.
Uiprobe's answer:
Frontend developers and UI designers who build from Figma and care that what ships reflects the design. That includes product teams and agencies, Webflow, Shopify, and custom front-end shops, who handle design QA by hand today. It increasingly includes developers using AI coding tools, who generate UI fast and need a reliable way to verify the output against the design.
OverlayQA's answer
OverlayQA was built out of 15 years of design-to-development handoff frustration. The QA process between design and engineering has always been scattered across screenshots in Slack, vague Jira tickets, and hours of back-and-forth. OverlayQA puts the entire visual QA workflow inside the browser where the work actually happens.
Uiprobe's answer:
We kept hitting the same annoying, draining task while building front-ends: manually checking whether the live page reflected the Figma design. Switching tabs, taking screenshots, leaving comments. We tried AI comparison first, but the results shifted between runs and we could not trust them. So we rebuilt the comparison to be deterministic, reading computed CSS, and made the output a list of findings rather than a judgment. Uiprobe is the tool we wanted while doing that work.
OverlayQA's answer
Chrome Extension (Manifest V3), React, TypeScript, Hono (backend), Neon (PostgreSQL), axe-core (accessibility engine), GPT-4o (AI visual analysis).
Uiprobe's answer:
We render the live page with a browser engine and read its computed CSS, then run a deterministic comparison engine that maps elements between the Figma frame and the rendered page. Design input comes through the Figma API, with a Chrome extension and a Figma plugin as entry points.
