Plausible Analytics [1] is an MIT Licensed alternative to Google Analytics. It is hosted at plausible.io but can also be self-hosted. The app server is written in Phoenix/Elixir. The self-hosted version is distributed as a Docker image. It is configured [2] with a PostgreSQL server for user data, a Clickhouse server for analytics data, and an SMTP server for transactional email. EDIT: according to markosaric, the data policy restricts the granularity of Active Users [3] to daily statistics for privacy reasons so the common Monthly Active Users (MAU) stat is not available.
