Packages.
What developers adopt across eight registries, in each registry’s own unit. Every figure says where it came from, and a number a registry does not publish is never shown as zero.
70,347 packages · 8 registries · Last observed OCT 24, 2026 · 07:34 UTC
18,154 packages · Most adopted · PyPI
Most adopted cannot rank these packages yet, so this order is not a ranking. Most adopted ranks by the percentile within each registry, and these packages have no adoption count (PyPI and Maven Central publish none) or none observed yet.
