The AI app builders currently tracked by BuilderProof. This page lists the panel and does not rank it: the June 2026 result sets were placeholder data and were withdrawn on August 21, 2026, so the lab currently publishes method, not scores.
Status: scores withdrawn, August 21, 2026
The scores that previously ranked this panel were placeholder data and were withdrawn on August 21, 2026. Our own reference list described those cells as v0.1 preview figures pending a public dataset, and the independently reproduced cycle promised for July 2026 was never run. BuilderProof does not retain the run artifacts that would let a reader reproduce them. The builders below are listed, not ranked. See our published methodology for the current evidence basis.
