Fusion: open-source alternative to Mixpanel, Hotjar

About Fusion

Fusion is a self-hostable, open-source platform for analyzing how people use web products and for engaging with them. It is described as an alternative to Mixpanel, Amplitude, Hotjar and Fullstory. The README states that the project is no longer maintained, so it is better treated as a reference or starting point rather than a supported product.

It combines a low-code analytics engine with visual analytics. Events such as page views, button clicks and form submissions are captured automatically once a tracking snippet is added, and visual recordings of user interactions are supported. Custom dashboards allow different chart types and timescales. For engagement, it offers live chat, in-app push notifications, email and micro-surveys, and email campaigns that can be triggered automatically.

Fusion is meant to be self-hosted, with the README providing Docker-based commands for production and development, and its pitch is avoiding large SaaS bills while keeping user data in your own hands. The stack includes JavaScript, Python and PostgreSQL. The repository lists its licence as other, so terms should be read before reuse.
