#Hashtag Metrics
Live hashtag analytics measured from the open social web — day-by-day usage, related tags, top posts, engagement and posting hours. A named source and timestamp on every number. Free, no login, no estimates.

Usage counts come from the Mastodon public tags, trends and search APIs (per-day uses and unique accounts, ~7-day window); post totals, engagement, co-used tags and posting-hour data come from the Bluesky public search API, measured over the latest sample of posts. Platforms that lock their numbers behind paid APIs (X, Instagram, TikTok) are not shown — we publish only what we can measure and name the source and fetch time on every figure. A number we cannot measure renders as a dash.
Agents and developers: the same numbers, as JSON — /api/hashtags/<tag>
