#packages

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.

Live PyPI (Python Package Index) download analytics from pypistats.org — no key, nothing stored. The adoption view of a Python package: how much it is downloaded, the daily trend, and the breakdown by Python version and operating system, distinct from the PyPI registry-metadata API in the catalogue (which describes a package — this measures how much the community actually uses it). The recent endpoint returns the headline download counts: last day, last week and last month. The overall endpoint returns the daily download timeline so you can chart growth. The python endpoint breaks downloads down by Python version, showing which versions the package's users are actually on. The system endpoint breaks downloads down by operating system — Linux, Windows and macOS. Build package-popularity dashboards, dependency-adoption trackers, "which Python version should we still support" tools and ecosystem-trend widgets on top of real PyPI download data. Look up any package by its PyPI name (requests, numpy, flask); names are normalised to lowercase and the version and system splits include each category's share of total downloads.
