PhantomBuster comes up in almost every conversation about LinkedIn automation, and for good reason. It is a capable tool for pulling data, exporting lists, and running outreach at scale. If your goal is extracting information or automating volume, it does that job well.
Pulling data and building relationships are different jobs, though, and most comparison posts blur them. This one tries to be fair to both tools, including the cases where PhantomBuster is the better choice.
What is the difference between Allen and PhantomBuster?
The difference is toolkit versus finished workflow. PhantomBuster gives you building blocks and you assemble the system. Allen gives you one system that is already assembled, for one purpose.

What is PhantomBuster built for?
PhantomBuster is an automation platform first. It offers a library of ready-made automations it calls phantoms. Each one does a single task: scrape a list of profiles, pull the people who engaged with a post, export a search, send a connection request. You chain them, schedule them, and send the results wherever you need them.
For a growth engineer building a custom pipeline across several platforms, that flexibility is the point and there is no real substitute. Its plans include AI filtering and writing, outreach campaigns, and integrations with CRMs and tools like Zapier and Make.
What it does not do out of the box is behave like a person who reads a post and responds to it. Its AI writing is general. It is not trained on how you write, and it does not give you a daily list of fresh posts from the people you want as customers.
What is Allen built for?
Allen starts from a different idea: let software do the searching, and keep the relationship yours. Each day it finds fresh LinkedIn posts written by people who match your audience by job title, writes a comment on each one in your voice, and posts them from your own account a few minutes apart. When someone replies, it emails you who they are and what they said, and drafts a direct message for you to send.
It is narrow on purpose. Allen comments. It does not send connection requests, direct messages or InMails, it does not visit profiles, and it does not scrape lists for export. The full list is in what Allen never does on LinkedIn.
The trade is volume for fit. Allen's Autopilot posts 5, 10, 15 or 20 comments a day, and posting by hand is limited to 35 a day, which is small next to what a scraping tool can push out. The bet is that a few comments a day in your own voice, on posts from people who could buy, do more than a few hundred templated touches.
How does each tool connect to LinkedIn?
This is the difference that matters most for your account, so it is worth being exact.
PhantomBuster connects using your LinkedIn session cookie, called li_at, and your browser's user agent. That is how its own help center describes setup. The automations then act inside your session from the cloud. PhantomBuster says it does not use bots or fake accounts or try to get around platform safeguards, and we are not claiming otherwise.
Allen connects through LinkedIn's official API. You sign in on LinkedIn's own page, and LinkedIn asks whether to let Allen post comments and posts as you. Allen never sees your password and never uses your cookie or your browser. Public posts are supplied by third-party data providers, so nothing is read through your account either.
LinkedIn's own rule is short. Its help page on prohibited software and extensions says it does not permit "any third party software, including 'crawlers', bots, browser plug-ins, or browser extensions that scrape, modify the appearance of, or automate activity on LinkedIn's website." The same page says breaking that can lead to an account being restricted or shut down.
LinkedIn went further in March 2026. In a post on authentic content and conversations it said comments posted "using a browser extension, script, or third party tool" without a person clicking the comment button "aren't allowed on LinkedIn", and that it may hide them or restrict the member.
That applies to our own product too, so here it is plainly. Allen's Autopilot posts comments for you. If you want every comment to go out by your own click, leave Autopilot off and post each one yourself. Allen still finds the posts and writes the comments.
We will not tell you how LinkedIn will treat any particular tool, ours included. LinkedIn writes and enforces its own rules and can change them. What we can tell you is exactly how Allen connects, which is why it cannot send messages or connection requests: the official API does not allow it. More in is Allen safe for my LinkedIn account?
How do the prices compare?
They charge for different things, so the sticker prices are not like for like.
PhantomBuster charges for automation capacity: execution time, AI credits, and how many automations you can run. When checked in September 2026 its plans were Start at $69 a month, Grow at $159 a month and Scale at $439 a month billed monthly. Billed annually they work out to $56, $128 and $352 a month, with 20, 80 and 300 hours of execution time.
Allen charges for one workflow. Basic is $39 a month for Allen three days a week. Professional is $97 a month for every weekday. Team is $197 a month for three seats. Every plan is free for 7 days. See plans and pricing.
If you need multi-platform capacity, PhantomBuster's model fits. If you need LinkedIn engagement only, the question is whether you would rather pay for the parts and build it, or pay for it already built.
When should you choose PhantomBuster?
Choose PhantomBuster when:
- You need data out: lists of profiles, post engagers, search results, emails.
- You work across several platforms, not only LinkedIn.
- You are technical, or have someone who is, and want to design your own system.
- You want automated connection requests and message sequences, and you have weighed the account risk.
- You already have the relationships side covered and need the data layer.
When should you choose Allen?
Choose Allen when:
- Your goal is conversations with a specific kind of buyer, not a bigger list.
- You want comments that sound like you, not a template.
- You do not want a tool holding your LinkedIn cookie or password.
- You want to see who replied, with the next message drafted.
- You have no time or wish to maintain automations.
Allen fits people whose next customer is on LinkedIn: founders, consultants, coaches, agency owners, recruiters, financial advisors and B2B sales reps. There is a setup guide for each on the help center.
Can you use Allen and PhantomBuster together?
Technically, yes. They do different jobs and do not get in each other's way. Some teams use a data tool to build lists and a separate tool for engagement.
One caution. Any tool that drives your browser session carries its own account risk, and that risk does not go away because another tool on the same account uses the official API. Allen's help center covers this in using Allen with other automation tools. If account safety is the reason you are looking at Allen, running a cookie-based tool beside it gives most of that benefit back.
Which one actually builds relationships?
Relationships come from being recognized, and recognition comes from showing up repeatedly with something worth reading. That is a small number of specific comments, in your voice, in front of the same kind of person, over weeks.
PhantomBuster can tell you who those people are and reach a lot of them quickly. Allen is built to do the slower thing: be in front of them a few times before any message is sent. We explain why that order works in why your LinkedIn outreach isn't converting.
