What Is Phantombuster Used For?
Phantombuster runs the browser actions you'd otherwise do by hand, over and over, and hands you back the results as a list.

The core idea: pre built scripts, not custom code
A Phantom is a packaged automation for one specific site action. You're not writing a scraper from scratch, you're configuring an existing one with a source URL and letting it run.
Example: the LinkedIn Post Commenter and Liker Scraper
This particular Phantom takes one LinkedIn profile URL as its source and collects everyone who has liked or commented on that person's posts. Paste the profile URL in as the source, save it, and the Phantom is configured.
It runs in the background
Once you flip a Phantom from off to on, it works without you watching it. That's the practical value: the automation is doing the repetitive part of browsing and collecting while you do something else.
Results land in a report
Open the Report screen for that Phantom to see results coming in as it runs. For a lead generation Phantom, that report is a list of names, useful as a starting point for outreach rather than a finished, qualified list.
A Phantom's output is a signal, not a guarantee
Someone liking or commenting on a post shows interest in the topic, not necessarily fit for whatever you're offering. Treat the list as a warm starting point to review, not a ready to message audience.
Where Phantombuster fits versus a plugin or manual scraping
A browser plugin usually automates one page at a time while you're actively on it. Manually collecting the same information means opening a post, scrolling the comments, and copying names by hand, which doesn't scale past a handful of people. Phantombuster sits between those two: it's automation you configure once, aimed at a specific source, that then runs on its own and hands back a structured list instead of requiring you to babysit a browser tab.
Why founders use it for early lead generation specifically
Cold outreach usually starts with a list of names that have no particular reason to respond. Engagement based scraping flips that: instead of a random list, you get people who already showed interest in a specific topic by liking or commenting on a related post. It's not a perfectly qualified list, but it's a meaningfully warmer starting point than a cold list pulled from a generic search.

Frequently asked questions
Is Phantombuster free to use?
Phantombuster offers a free tier that's enough to run a Phantom like the LinkedIn scraper on a small scale. Paid plans exist for higher volume or more frequent runs, but getting your first list of leads doesn't require a paid account.
Does Phantombuster only work with LinkedIn?
No. Phantombuster offers Phantoms for a range of sites and actions, LinkedIn is simply where a large share of its lead generation use cases concentrate, since profile and post data there maps well onto sales and outreach workflows.
Is scraping LinkedIn with Phantombuster against LinkedIn's terms?
LinkedIn's terms of service restrict automated data collection, and this is worth knowing before relying on any scraping tool at scale. Most people using a Phantom like this run it lightly, on a single source profile at a time, rather than at a volume likely to trigger platform enforcement, but the underlying tension exists regardless of tool.
How is a Phantom different from an API integration?
An API integration talks directly to a service's own data endpoints, which LinkedIn tightly restricts for this kind of use. A Phantom instead automates the browser itself, essentially clicking and reading the page the way a person would, which is why it can reach data an official API wouldn't expose.
What do I actually get back after running a Phantom?
A structured report, typically a list of profiles or names with whatever fields that Phantom collects. For the LinkedIn Post Commenter and Liker Scraper, that's the people who engaged with a source profile's posts, viewable in the Report screen as the scrape runs.
Choose a source profile with real audience overlap
The people commenting on a founder's posts only make good leads if that founder's audience actually resembles your buyer. A large but unrelated audience still produces a long list, just not a useful one.
Let the scrape actually finish
Checking in too early almost always shows an empty or partial report. Give the Phantom real time to run before judging whether the source profile was a good pick.
Treat the list as warm, not qualified
Engagement signals interest in the topic, not fit for your specific product. Skim the list before reaching out at scale rather than messaging every name it returns.
Know the terms of service tradeoff going in
Automated collection sits in tension with most platforms' terms. Running lightly on a single source at a time is a different risk profile than running at high volume across many sources.
