# Rainlytics

> Rainlytics is self-hosted web analytics for sites served by CloudFront. It runs inside one AWS account, reads the access logs the CDN already writes, and ships no third-party JavaScript to the pages it measures. There is no always-on infrastructure, and the data never leaves the account it was collected in. It is an npm package, @kensio/rainlytics.
