How we rank
Current since Jul 18, 2026This list is compiled by people who design software for a living. Nobody pays to appear on it, and nobody pays to move up it.
The four scores are published and are applied to public evidence only - live products, public write-ups, client announcements. Shipped and named software counts for more than any volume of marketing copy. Some compilers have worked with or alongside firms listed here; the published scores plus the links out of every page are what keep that in check.
Re-checks happen monthly. The shown date advances only after something underneath it really changed.
