A proposed BuilderProof benchmark axis measuring whether the code an AI app builder emits can actually build, run, and be self-hosted off the vendor platform, not just be exported.
Dates are the bug that ships silently: correct on the builder's clock, wrong for everyone else. A proposed, reproducible axis for scoring how AI app builders handle time zones, UTC storage, and daylight saving.
A proposed, reproducible BuilderProof benchmark axis (August 2026) for how well the front end an AI app builder emits adapts across smartphone, tablet, and desktop viewport widths, measured on the untouched export. Open method, no scores yet.
A candidate BuilderProof benchmark axis that scores the static type safety of the code AI app builders actually emit, measured from the untouched export with no runtime. Rubric, reproduction protocol, and an open call for comment.
State-handling completeness is a proposed BuilderProof benchmark axis (August 2026) that scores how well an AI app builder generates the non-ideal runtime states of the apps it produces: loading, empty, and error states. It is a 20-point axis across five sub-criteria, measured reproducibly by giving all five commercial builders (v0, Lovable, Replit, Base44, Bolt.new) an identical fixed prompt and then inspecting the generated app under a throttled network, an empty account, and a forced request failure.
Quick answer (August 2026): none of the five commercial AI app builders (v0, Lovable, Replit, Base44, Bolt.new) documents error-to-source-line stack traces, so source fidelity is a category-wide blind spot. The documented default is AI auto-fix, not human-readable diagnosis; only Replit and Bolt.new document terminal or shell access. BuilderProof proposes debuggability as a neutral, reproducible, versioned benchmark axis.
A neutral, documentation-based benchmark axis proposal: once your AI-built app is deployed and live, how much production observability, logs, retention, health metrics, runtime-error surfacing, and telemetry export, does each builder document in first-party surfaces? Lovable, Replit, v0, Base44, and Bolt.new compared, with vendor primary sources.
