Prototype against the API on a free tier or free credits

A global story is meaningful for any software product, so it can be compared across the whole site — every product’s verdict on free-tier-prototyping across all 2 arenas that carry it, judged from public evidence.

Adoption among tracked products

83.3%

Prototype against the API on a free tier or free credits: 10 of 12 tracked products pass (full or partial), across 2 arenas.

Tracking since Sep 2026 — the diffusion curve appears once a second month of tracking accrues.

Honest approximation: what this curve can and can’t show

We don’t have per-verdict change history, so the curve shows adoption among products as they enter tracking (first score-history entry), with each product carrying its current verdict — not the moment each product shipped the capability. Exact verdict history accrues from here forward.

Verdicts are judged per arena against that arena’s evidence packs, so the same tier can rest on different evidence depth across arenas — follow a row to the product page for the full rationale.
