Umami
An open-source privacy analytics tool with pages, events, sessions, funnels, retention, teams, and shareable dashboards.
Why use it
Indie developers can measure websites, news, and web-demo actions with a small infrastructure footprint.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
It is less deep than a full product-analytics suite and self-hosting still needs databases, backups, and upgrades; cookie-free use still requires appropriate privacy notice.
