Probes

Last updated

A probe defines a persistent visual comparison between a Figma design and a live webpage.

It represents what is being compared and serves as the foundation for all visual validation in Uiprobe.

What a probe connects

A probe connects two inputs:

  • a Figma frame, which acts as the design reference
  • a live webpage URL, which acts as the implementation reference

Once created, the probe remains the same, even as its results change over time.

Running a probe

When a probe is run, Uiprobe performs a visual comparison between the design and the webpage.

The result of each run is stored as a new probe version. Running a probe again never overwrites previous results.

Probes and versions

A probe acts as a container for its versions.

Each version represents a snapshot of the comparison at a specific moment in time, allowing users to review visual changes as designs or implementations evolve.

Probes with no issues

A probe run may result in a version with zero detected issues.

This indicates that, at the time of the run, the live webpage visually matched the design within the detection limits of Uiprobe.

Probes and sharing

Probes can be shared using public, read-only links.

Sharing provides access to the probe’s results and version history without allowing viewers to modify or re-run the probe.
