PhantomBuster operates through cloud-based "Phantoms"—pre-built automation templates that perform specific tasks on behalf of the user. For the Auto Liker specifically, the tool uses session cookies, often retrieved via a PhantomBuster browser extension , to safely connect to a user's account and perform actions. Users can provide a list of profile or post URLs, often via a public Google Sheet, and set specific launch parameters to control the frequency of interactions. Accessibility and the Free Tier
If you own a Facebook (not a personal profile), you can use ManyChat or MobileMonkey (both have free plans up to 1,000 contacts). These tools auto-respond with likes and reactions based on keyword triggers. phantombuster facebook auto liker free
