Overview¶
The software and data resources of the Chemistry Development Kit ecosystem, collected once a week from public sources.
Per-source detail is on the Methods page.

3 registries
Releases¶
Releases per year. A tagged release of a project's repositories, from GitHub Releases and git tags.
Source: github · collected 2026-08-31 · download CSV
Downloads¶
Each registry counts over its own window, and the two are never added together.
Registry downloads, all time. The registry's own lifetime download counter, for registries that publish one.
Source: ecosystems · collected 2026-08-31 ⚠ incomplete · download CSV
Registry downloads, last 30 days. Downloads in the last 30 days, as reported by registries that publish no lifetime counter.

Bioconductor distinct IPs per month — not collected. The bioconductor source did not return data on the last run (2026-08-31), so this figure is not shown rather than drawn from stale or partial values. See collection status.
Dependents¶
Maven Central publishes no download figures, so for the Java libraries this is the only measure of use a registry offers. It is counted the same way everywhere, and the registries do not see each other.
Packages depending on it. Other published packages that declare a dependency on one of these, as counted by the registry it is published in.
