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 · 09:20 UTC
5,094 packages · Most adopted · Maven Central
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.

What each registry publishes
Each registry counts adoption in its own unit and window, so raw numbers are never compared across registries. Popularity is a package’s percentile within its own registry. How packages are measured
