Counterscale is an open-source web analytics service that is self-hostable on Cloudflare's developer cloud. It can be deployed as a single Cloudflare Worker that serves a JavaScript reporting snippet. Counterscale hosts a reporting endpoint and has a dashboard UI written in Remix. The heart of Counterscale is the Workers Analytics Engine, which is a set of managed services built on top of Clickhouse that allows for the writing and querying of analytics-style data at a massive scale. The service is essentially free for most users as it falls within Cloudflare's free plan limits.
