InstaSDM vs DMFox: Why Operators Are Switching
DMFox is a browser extension for Instagram DM automation. InstaSDM is infrastructure. Here's the difference in practice.
The core difference
DMFox runs in your browser. Your computer must be on. Your browser must be open. Your IP must stay the same. Instagram sees browser automation signals.
InstaSDM runs on our servers. Close your laptop. Your campaigns continue. Dedicated IP per account. No browser extension footprint.
