Self-hosted web analytics for AWS sites, built on CloudFront logs.
Rainlytics runs the whole analytics pipeline inside your own AWS account. Most of what it reports is derived from the CloudFront access logs your distribution already writes. A measured page downloads no analytics JavaScript, opens no extra connection, and resolves no extra hostname.
An optional beacon covers what an access log cannot see accurately, such as route changes in a single-page app, Core Web Vitals, custom events and JavaScript errors. It is bundled into the site's own JavaScript and reports back through the site's own domain (no second host, no separate script tag).
Everything runs on usage-priced AWS services, batched and precomputed on a schedule rather than processed per request. Nothing in the pipeline is always on, and a low-traffic site should cost cents a month.
CDK constructs for the collection half of the pipeline. A distribution's access logs land in an S3 bucket, partitioned and carrying the field set the rollups will read.
import { CloudFrontLogDelivery, LogBucket } from "@kensio/rainlytics/cdk";
const logs = new LogBucket(this, "RainlyticsLogs");
new CloudFrontLogDelivery(this, "RainlyticsDelivery", {
distributionId: "E1EXAMPLE1234",
logBucket: logs.bucket,
});That stack has to be in us-east-1, which is the only region CloudFront log delivery can be configured from. See the log bucket and log delivery pages.
Querying and rollups come next. Nothing reads the data back yet.
Experimental and pre-1.0. The construct API changes without a major version behind it, and the only consumer so far is the maintainer's own sites.
rainlytics.com is the canonical home.
rainlytics.dev, rainlytics.net and rainlytics.app redirect to it.
