What happened
A public showcase collects 57 self-contained web demos across six collections: generative art, simulations, instruments and explorable worlds. The page states each piece was designed, built and QA'd end to end by fleets of Claude Fable 5 agents, over one day, and that every demo is a single HTML file with no dependencies.

What this shows benchr fetched the showcase on 2026-09-04 and measured it: 0 external scripts, 0 external stylesheets, 0 external images, in one 4,508,215-byte document. The no-dependencies claim holds for the page benchr can measure. The claim of 57 separate files does not survive contact with the site: the demos are inside that one document.
