The tests behind every claim

Every speed and time claim on this site rests on a test you can read here. The tests ran on September 24, 2026, and the recorded build on September 25, 2026.

What the tests found

Build time

Each of 30 test builds finished in under 80 seconds, with a median of 28 seconds.

Phone speed

Every one of the 123 demos scored 99 or more on a phone speed test, with a median of 100.

A recorded build

One real request became a preview in 47 seconds, and the preview scored 100.

How we tested

Build time: the method and all 30 builds

Method: platform/generate.py --prompt <fictional business> --fictional --no-deploy on the studio machine (Windows 11, residential connection), one after another; wall time from the command to the rendered site, and the model step alone (claude-sonnet-5 through ai/build.py with the validator). The 90th percentile was 50 seconds, and the model step alone had a 24-second median.

30 builds, 0 failed.

Phone speed: the method

Method: tools/lh_one.mjs: Lighthouse 13 mobile form factor, simulated throttling, performance category, on each demo home page at https://showroom.mysiteslive.com. 123 of 123 demos scored 95 or more, and the lowest scored 99. The showroom holds every demo that was measured.

The recorded build

A storefront form for a fictional bakery was filled on September 25, 2026, and the preview answered 47 seconds after the request. The request went to the builder at once in that run; a normal request waits for the builder's next pass, which runs every 5 minutes.

Questions

What does a phone score mean?

It is the Lighthouse performance score on a simulated phone, out of 100.

Why can a real visit be slower?

Real phones and networks vary. The test uses one fixed setting, so every result compares fairly with the others.

When did the tests run?

On September 24, 2026, and the recorded build on September 25, 2026. Each claim on the site cites the test behind it.
