Chrome Extension

The Uiprobe Chrome Extension connects live webpages to their corresponding probes, allowing you to run comparisons and review probe status without leaving the page you’re inspecting.

It acts as a lightweight control surface that sits alongside the web app, optimized for quick checks and repeat runs during development and review.

What happens when you open the extension

When you open the extension on a webpage, Uiprobe first determines whether you’re authenticated and whether a probe already exists for the current URL.

If you’re not signed in, the extension prompts you to authenticate via Figma. Once signed in, this authentication is reused across Uiprobe, so you don’t need to sign in again when moving between the extension and the web app.

If you’re signed in, the extension automatically checks whether the current webpage is already linked to a probe.

Active probe state

If a probe exists for the current URL, the extension displays the active probe.

The probe card shows:

  • the probe name
  • the current status (for example: up to date, running, or outdated)
  • the number of detected issues in the latest version
  • the timestamp of the last run

From this state, you can:

  • Run probe to create a new probe version
  • Open in app to inspect results in the full Probe Inspector
  • Open Figma to jump to the linked design frame

Running a probe from the extension never overwrites previous results. Each run creates a new version, just like running a probe from the web app.

Creating a probe from the extension

If no probe exists for the current webpage, the extension offers the option to create one.

Creating a probe from the extension requires a Figma frame URL. Once provided, Uiprobe validates the input and confirms whether the frame can be used as a design source.

After validation:

  • the probe is created
  • the initial comparison is run
  • the extension transitions into the active probe state

From that moment on, the webpage and the Figma frame are linked through the probe.

Relationship to the web app

The Chrome Extension is designed to complement the web app, not replace it.

You can use the extension to:

  • detect whether a probe exists for a page
  • run new probe versions
  • jump directly to detailed results

You must use the web app to:

  • review issues in depth
  • navigate versions and comparisons
  • manage probes beyond running them

This separation keeps the extension fast and focused while leaving deeper analysis to the full interface.

What the Chrome Extension is not

The Chrome Extension is intentionally limited in scope.

It does not:

  • run probes in the background
  • support multiple probes for the same URL
  • allow deleting or replacing probes
  • manage sharing or access controls

Its role is to make running and accessing probes frictionless while you’re working on a live page.
