Hashtag.org Hashtag Metrics vs Keyword Tool

Hashtag.org Hashtag Metrics is a free web and API service for live hashtag usage, related tags, top posts, engagement and posting hours. No login is required, and the directory offers browsing across 1,251,230 measured tags. Usage counts come from Mastodon public tags, trends and search APIs, while post metrics come from the Bluesky public search API. Mastodon counts cover roughly seven days; Bluesky metrics use the latest sample of posts. Every figure includes a named source and fetch time, while values that cannot be measured appear as a dash. Metrics for X, Instagram and TikTok are omitted because their numbers are behind paid APIs. The same measurements are available as JSON at `/api/hashtags/`. The service also describes an auction with public bids for claiming a hashtag as a #name on the hashtag.org network. The free plan costs nothing.

Keyword Tool generates long-tail keyword suggestions from autocomplete when given a seed term. It supports keyword and competitor research across 16 platforms, including Google, YouTube, Bing, Amazon, TikTok, Reddit, Pinterest and Google Trends. The free tool works without an account and can return 750+ Google autocomplete keywords. Paid plans add search volume, cost per click, competition scores, device breakdown and historical trends; they also support search-volume enrichment for up to 1,000 keywords per request, with daily capacity depending on the plan. Access includes the web interface, API and MCP, and Claude, Cursor and ChatGPT are named as compatible assistants. Google coverage includes 190+ countries, 68,000+ locations and 50+ languages. The site says Google and Bing metrics come from planner ecosystems, while volumes for other platforms are modeled estimates based on clickstream signals. Web, API and MCP share a daily request pool, and available MCP tools can vary by endpoint, plan and rollout status. Paid plans start at $68 a month. There is no free trial; the pricing FAQ lists a 30-day money-back guarantee for paid plans.
