Umami is an open-source web and product analytics platform made by Umami Software, Inc. Web analytics means counting and describing the visits to a website: how many people came, from where, and what they did. Umami does this without cookies, without cross-site tracking and without automatic collection of personal data, so most sites need no cookie consent banner.
The dashboard shows pageviews, visitors, bounce rate, average visit time, referrers, locations and devices. It also reads UTM parameters, the tags in a link that name a marketing campaign. Custom events record actions such as button clicks, form submissions and signups. Reports include funnels (how many visitors pass each step toward a goal), journeys, retention and revenue; the higher paid plans add session replays and heatmaps. An API and an MCP server let other programs and AI assistants query the data.
The code is open source under the MIT license. Self-hosting needs a server with Node.js and a PostgreSQL database. Umami Cloud is the hosted version, with a free plan and monthly plans priced by the number of events.
