Mobile UI QA loop closed

Ship Pixel-Perfect Mobile UIs.Zero Manual QA.

Stop chasing pixels through screenshots and review comments. Visor gives agents a live mobile feedback loop so they can inspect, compare, patch, and rerun until the screen matches.

Interactive comparison

Kill the screenshot feedback loop

The same prompt goes from "close enough" to verified when the agent can inspect the running app, compare against Figma, and rerun the patch loop.

Target, miss, verified fix

Track the exact gap between the intended Figma screen, a one-pass implementation, and the Visor-assisted result.

Faster loops, fewer pixel chases

Give agents the same visual context a reviewer would ask for, then let them close the gap themselves.

Inspect The Runtime

Capture real screenshots and UI structure so the agent debugs the screen users actually see.

Drive Mobile Flows

Tap, type, navigate, and verify iOS or Android screens from one CLI-controlled loop.

Catch Pixel Drift

Compare live UI against Figma and flag missing icons, clipped content, spacing misses, and layout drift.

Rerun Until Clean

Collect artifacts, patch the implementation, and repeat verification without waiting on manual QA.

Technical teardown

How the loop closes

A deterministic path from running app to visual correction, built for agents that can act on evidence.

01

Attach runtime

Start Visor against the iOS or Android app and expose the active screen to the agent.

02

Read screen state

Capture screenshots and UI data from the live app instead of stale review artifacts.

03

Diff against Figma

Compare the implementation to the design target and identify visual drift.

04

Patch and rerun

Apply the fix, capture a fresh screen, and repeat until the mismatch is gone.

Ready for the next pass

Stop handing pixel QA back to humans

Install Visor, connect your mobile app, and give your agent the evidence it needs to ship the screen.
