I'm building FollowGuard (https://followguard.app) - it's a privacy-first Instagram analytics tool.
I got tired of seeing people lose their accounts to "unfollower" apps that require login credentials and use unofficial APIs. Instead, I built this to parse official Instagram GDPR data exports 100% client-side in the browser.
It’s a Vue 3 + TypeScript SPA. There is no backend; all the ZIP extraction and JSON parsing happen locally so the user’s data never leaves their machine. I even added a "Security Audit" feature to help people find suspicious login activity in their own data.
My biggest challenge right now is the UX friction. To stay safe, the user has to navigate an 11-step manual export process on Instagram to get their data. I’m trying to figure out if the "privacy/safety" benefit is enough to convince non-technical users to jump through those hoops.
