Uiprobe Compare Your Site

Compare implementation to design without switching tools.
Uiprobe lets you run visual checks right where you build. Open any page in Chrome — including localhost and login-gated pages — paste your Figma frame URL, and run a probe. You'll see exactly where your implementation diverges from the design: spacing, typography, color, layout. Before review. Before anyone else flags it.

Uiprobe requires a Figma account. Sign in with Figma to get started — it's free..

How it works
1. Open the page you’re working on in Chrome.
2. Click the Uiprobe icon to launch the extension.
3. Paste your Figma frame URL — the webpage URL is filled in automatically.
4. Run the probe to see your findings in the Uiprobe app.

If you’ve already created a probe for this page, you can re-run it to check for changes.

Key features
• Instant visual validation — Detect spacing, typography, color, and layout differences between your design and implementation.
• Works on localhost — Run probes on pages behind a login or on a local dev server. No workarounds needed.
• Quick updates — Re-run comparisons in one click to validate your latest changes.
• Findings, not guesswork — See exactly what's off and how to fix it, without switching between tabs and taking screenshots.
• Design intent preserved — Catch where the implementation diverges from the Figma design before it ships.

Why teams use Uiprobe
Most teams still check design implementation by eye — switching tabs, taking screenshots, leaving comments in Figma. Uiprobe replaces that loop.
It gives you clear, specific findings on what's off — and how to fix it — before anyone else sees the page.

Frontend developers catch visual drift early, without guessing.
UI designers stop babysitting implementations and writing repetitive feedback.
QA engineers get an objective, repeatable check against the original design.

Requirements
• Figma account — any seat type works. View and Collab seats are limited to a handful of probes per month by Figma's API; a Dev or Full seat removes
• Google Chrome
• Active internet connection

What’s new (April 2026)
• Uiprobe is now free to use — no invite required. Sign in with your Figma account and run your first probe.
• Findings are now grouped by type: Properties, Spacing, and Unverified — making results easier to scan and act on.
• Spacing findings now include a tolerance filter (Pixel-perfect, Standard, Flexible) so you can focus on what matters.
• Improved detection: typography, color, border, opacity, and content findings are now reported separately from spacing.
