Umami

Umami is an open-source web and product analytics platform providing reports on acquisition, on-site behavior, conversion funnels, retention and revenue. It uses no cookies by default and collects no personally identifiable data, so most sites can drop the cookie consent banner. It addresses conventional analytics tools that rely on cookie tracking and split traffic, heatmap and product analytics across separate tools that are hard to reconcile, bringing those datasets into one reporting layer.

The code is open and can run on your own infrastructure or through its hosted cloud service; under either model the data is never sold. Features include custom events, user journeys, session replay, UTM attribution and period-over-period comparison. Self-hosted installations from version 3.4 onwards ship an official MCP server, letting compatible AI clients run read-only queries over traffic, funnel, retention and other metrics. It is a separate entity from the on-chain yield protocol of the same name and sits in data analytics rather than crypto.
