Homebrew Environment Configuration Events (365 days)

/api/analytics/homebrew-env-config/365d.json (JSON API)

Start Date: 2025-09-20

Total Variables: 161

Total Events: 129048534

Each event samples one randomly-chosen configuration variable from a brew run and records whether the user left it unset, set it to its default value or set it to a non-default value. Variables Homebrew exports itself (e.g. HOMEBREW_EDITOR from EDITOR) count as unset. Values are never recorded.
