Ship interfaces that measure up

Halo renders your app, measures what a person would actually see, and opens a reviewable branch with the fixes. No screenshots-to-code guesswork.

Three rules the whole product follows

Measured, not guessed

Every number on a report comes from the rendered page. Nothing is estimated from a screenshot and presented as a fact.

One definition, everywhere

Tools, permissions and the wire protocol all derive from a single registry. Adding a capability without a permission refuses to boot.

Search and replace, never diffs

A patch names the exact text it expects to find. A stale hunk fails loudly instead of applying to the wrong place.

It reports what it cannot measure

Brand fit, copy tone and visual taste are listed as not scored rather than scored badly. A tool that grades everything is not measuring anything.

A desk with a laptop and notes
“It found a hundred and one instances of sub-12px text on our own marketing site. We had shipped that page four times.”
