WebSocket

Protocol · Catalog tech@1

Full-duplex communication over a single connection.

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. WebSocket 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.

Snapshot OCT 24, 2026 · Scoring tech@1

Official repository stars: No official repository; The catalog lists no official repository, so this signal does not apply.

Adoption by registry

The growth of WebSocket’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.

Packages

“Is” packages are WebSocket 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.
