Coding
Coding compares products. The composite uses a free tier, entry price, the product's own App Store rating and review count, and a benchmark only when the board names that product's harness. Model Elo and a lab model's SWE-bench row are not used. A tool under half the category weight is labeled insufficient data and has no numeric rank.
