Our verdict on Hashtag.org Hashtag Metrics

Hashtag.org Hashtag Metrics is a free web tool for examining hashtag activity across the open social web. It suits marketers, researchers, and developers who need usage counts, unique-account counts, related hashtags, recent-post indicators, engagement metrics, posting-hour analysis, and trending hashtag data. The service requires no login, and each figure displays a named data source and fetch timestamp. Developers can access the same hashtag metrics through a JSON API.

Pricing is straightforward: the product is free, with no paid tier described for Hashtag Metrics. That makes it useful for exploring hashtag activity without a subscription decision or account setup. The published feature set centers on measurement and discovery, including day-by-day counts, related-tag exploration, recent posts, engagement indicators, and a trending hashtag index. Its approximately seven-day measurement window makes it better suited to recent activity checks than longer historical analysis.

Its ecosystem fit is focused on public Mastodon tags, trends, and search APIs, plus the Bluesky public search API. This gives the product a defined open-social scope and makes the JSON API relevant for developers building workflows around those sources. It is a focused analytics option rather than a broader social campaign-management suite: the available capabilities describe hashtag measurement, discovery, and trend analysis, not verified campaign-management functions. Choose it for free public-social hashtag research, lightweight monitoring, or programmatic metrics access; choose an alternative if your work depends on wider platform coverage, longer historical windows, or campaign management.
