Build Test Lab — measured AI builders

We build the same app
in every AI builder.

Then we publish the measurements: what shipped, what broke, what it cost, and how long it took. No opinions. No sponsored rankings. The raw test files are on every review page.

Affiliate disclosure: some links on this site are affiliate links. If you sign up through one, we may earn a commission. Measurements are recorded before any commercial relationship is considered, and every test can be re-run from the published artifacts.

How a test works

  1. 01

    One fixed spec

    The same booking app, versioned in a public test spec. Every builder gets the identical prompt and requirements.

  2. 02

    Measured, not judged

    An automated suite checks the deployed app. Features pass or fail. Time, credits and attempts are logged.

  3. 03

    Artifacts published

    Screenshots, logs, pricing and failure cases sit next to the verdict. Anyone can check the claim.

Tests in progress

The first run is being set up. Every builder tested against booking-app-v1will appear here, with dates and raw results.
