OpenAnalytics

Note: This project took significantly more than 9 hours. I originally started building OpenAnalytics about a year ago, before Flavortown, and spent more than 50 hours working on the core system at that time.

What did you make?
I built OpenAnalytics, an open-source analytics API that developers can run on their own infrastructure to track traffic on their websites or apps. It provides metrics like total visits, unique visitors, sessions, bounce rate, time spent, most visited pages, visitor location, device information, and referrer data. It also returns preformatted datasets that can be used directly with charting libraries like Recharts or Chart.js.

What was challenging?
The main challenge was designing the session tracking and data structure so metrics like sessions, bounce rate, and time spent could be calculated accurately. It also took effort to format the analytics data so it could easily be used in dashboards.

What are you proud of?
I’m proud that the project is fully open source and self-hostable, allowing developers to control their own analytics data instead of relying on third-party services. I’m also proud that the API outputs structured data that makes building analytics dashboards much easier.
