Yes

A Chrome extension reading engagement signals the user's own account can see, a Rails/Vue backend, and Stripe billing — all shippable. The AI scoring and auto-reaction features add effort but no hard blocker. Nothing here requires a licence or human delivery.

Why people pay FriendFilter + GroupFilter

120,000 existing users, a Chrome Web Store Featured badge, and a 100K email list built since 2019 give this product visibility and credibility a fresh copy starts without. Subscribers also accumulate archived connections and engagement history they would lose by switching.

Product complexity
Moderate
The app must read Facebook engagement signals, score connections with AI, and surface ranked results.
Data
Moderate
Engagement signals come from the user's own Facebook account via available platform data.
Integrations & infrastructure
Low
Standard hosted web app with Stripe billing and no unusual third-party infrastructure.
Human operations
Low
No staff are needed to deliver the product once it is built and running.
Regulation / hardware
Low
No licence or approval is required to sell Facebook analytics software to consumers.
