Built a custom analytics platform with embeddable tracking scripts, real-time processing, and dashboard visualization for multiple websites

Problem

I wanted a centralized analytics system for all my websites without relying on third-party analytics platforms. The challenge was creating a lightweight tracking system that could securely collect client-side analytics data across multiple domains while maintaining proper API security and browser compatibility.

Solution

Developed a script-based analytics architecture where websites embed a tracking snippet containing a unique API key. The script dynamically fetches a tracker file from the Trackio CDN, collects analytics data from the client side, and securely sends it to the backend for processing and dashboard visualization. To solve cross-origin API access issues, allowed website domains were dynamically managed and validated through server-side CORS configuration.

Overview

Trackio Analytics is a full-stack analytics tracking platform designed for websites using lightweight embedded script integration. Website owners can add a custom tracking script with an API key into their HTML projects, allowing Trackio to collect visitor and analytics data in real time and present it through a modern analytics dashboard with graphs, metrics, and website management tools.

Results & Impact

Successfully built a reusable analytics platform for personal websites, providing centralized tracking, analytics visualization, and deeper understanding of browser-side tracking systems, API security, and real-time data processing.
