Integrations & infrastructure
Low
No named third-party service integrations beyond Stripe billing are required.
Human operations
Low
Scans run automatically on demand with no human work involved in delivery.
Regulation / hardware
Low
The tool uses only public Instagram data and requires no user login or credentials.
