Full entry on Wiktionary →

Extensibility is a software engineering and systems design principle that provides for future growth.

#extensibility across platforms

every network with a public tag surface

Follow #extensibility straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/extensibility
