Momentum

Each signal is ranked as a percentile among the technologies that have it. A signal without enough history is not counted, and never shown as zero. How momentum works

Momentum

Collecting1 of 5 signals

No score yet. Momentum is published only when at least 2 of the 5 signals have history. LangChain has 1, so there is no single number: each signal is shown on its own below. It is not a zero, and nothing is estimated in its place.

Adoption by registry

The growth of LangChain’s own packages, one row per registry in that registry’s own unit. Registries count different things over different windows, so they are never added together.
