How I Built a Chrome Extension to Analyze Viral Social Content (Statly)

As a developer and creator, figuring out what actually drives engagement on social platforms like Instagram, TikTok, and X usually requires hours of manual digging or expensive analytics tools.

To solve this, I built Statly, a Chrome extension that turns any Instagram, TikTok, or X account into a ranked report of what’s actually working.

Why I Built It

Most social analytics tools give you high-level vanity metrics, but they don't break down content performance at a granular level. I wanted a lightweight tool that lets you:

• Audit growth: Instantly see top-performing posts for any profile.

• Study competitors: Analyze viral formats before everyone else catches on.

• Zero friction: Works directly inside your browser without needing credential sharing.

Tech Stack

• Frontend: Vanilla JS / Chrome Extension API (V3)

• Backend: Node.js

• Payments: Lemon Squeezy
