#popularity

Live Firefox add-on stats from the official Mozilla Add-ons (AMO) API — no key, nothing stored. The adoption-and-reputation view of the Firefox ecosystem: how many users an extension or theme has, how it is rated and reviewed, and which add-ons are most popular, distinct from the other developer-ecosystem and package APIs in the catalogue. The addon endpoint returns a single add-on in full — its average daily users, weekly downloads, the star rating with review count, authors, version, type and categories. The search endpoint searches add-ons sortable by users, rating or relevance, each with its user count and rating. The top endpoint returns the most-used add-ons, optionally filtered to extensions or themes. Build extension-popularity dashboards, "is this add-on still maintained and trusted" widgets, competitor trackers and developer-portfolio tools on top of real Mozilla Add-ons data. Look up an add-on by its slug (ublock-origin, darkreader); average daily users is the headline popularity metric and the rating is the community reputation.

Live install analytics for Homebrew, the macOS and Linux package manager, from the public formulae.brew.sh feed — no key, nothing stored. The adoption view of the Homebrew ecosystem: how much each command-line formula and each desktop-app cask is installed, and the most-installed packages overall, distinct from the Homebrew formula-catalog API in the catalogue (which describes a package — this measures how much it is actually used). The formula endpoint returns a command-line tool's install counts over 30, 90 and 365 days plus install-on-request, with its version and description. The cask endpoint returns a desktop app's install counts. The top endpoint returns the most-installed formulae or casks over a chosen window, ranked. Build developer-tool popularity dashboards, "is this tool still maintained and used" widgets, package-trend trackers and ecosystem-health tools on top of real Homebrew analytics. Look up a formula by its name (wget, node, ffmpeg) or a cask by its token (google-chrome, visual-studio-code); counts come from Homebrew's opted-in user analytics.

How popular is that npm package? Get download counts and trends for any npm package straight from npm's public download API. Pull the total downloads over a period (last day, week, month, year or any custom YYYY-MM-DD:YYYY-MM-DD range), the full per-day download time series, the monthly totals over the last year to spot growth or decline, and compare several packages side by side ranked by downloads (up to 128 at once, scoped @org/name packages supported). Every call is live (no cache). 5 endpoints. Built for popularity dashboards, package-comparison pages, trend charts, dependency-health scoring and "which library won" analyses. Distinct from an npm registry-metadata lookup — this is the download time series. No upstream key, no cache.

US given-name popularity from 1880 to 2008 as an API — the top 1,000 names per year for each sex (SSA-derived dataset, 6,782 names). Pull a name's full popularity trend (e.g. Emma → girls: rank #1 in 2008, peaked again in 1881), get the top names for any year (e.g. 1990 → Jessica, Ashley, Brittany), or search names by prefix/substring. Each data point carries the year, the share of births (percent and per-million) and the rank. Ideal for name-trend visualisations, baby-name apps, nostalgia/genealogy tools and data journalism.
