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

Collecting0 of 5 signals

No score yet. Momentum is published only when at least 2 of the 5 signals have history. WebAssembly has 0, 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.

Packages

“Is” packages are WebAssembly itself; ecosystem packages depend on them. The two are counted separately and never added together. Adoption is each registry’s own figure, with its percentile within that registry.

Is 0the technology itself, most-adopted first

No package is linked as WebAssembly itself.

Ecosystem 0packages that depend on it, most-adopted first

No package in the catalog depends on WebAssembly’s own packages.
