Evaluation
IBM Plex scores 58.3/F on the Designesy Compliance Index — 7 of 42 checks passed, 2 failed, 12 warned, 18 skipped. The cohort mean is 69.3/D across 30 scored sites. IBM Plex sits 16% below the cohort mean.
Strongest category: Identity at 75.0%. Weakest scored category: Tokens at 0.0%. The gap between best and worst is the finding — most systems are strong in one dimension and absent in another.
F-grade means IBM Plex scores below 60 — the contract's pass threshold. The failing checks are not subjective: they are missing CSS primitives that the contract requires at :root.
This evaluation is deterministic — no LLM, no human judgment, no survey. The same 42-check engine that scored IBM Plex scores every site on the leaderboard. Re-score plex.ibm.com live to see if anything has changed since 2026-08-03.
