PostHog is an open-source product analytics platform. It helps you track user behavior across your website and applications. It also offers event capture for frontend and backend events. You can also set up event tracking at an identifiable user level (if you choose to identify your users).

PostHog offers one-click deployments for Heroku, AWS, and Render. It also provides tutorials to deploy using Docker, Kubernetes, or directly from your source. You can check their detailed deployment instructions for how to deploy on all the main cloud providers.

PostHog is the only open-source product analytics tool. While there are many other SaaS options (Mixpanel/Amplitude/Heap) similar to PostHog, all of them require sending your data to third parties. Also, they charge based on volume.
