Booost vs PhantomBuster: a toolbox of a hundred automations, or one product for one network.

The short answer

PhantomBuster is not a LinkedIn tool that happens to do other things; it is a cloud automation toolbox — "100+ automations & workflows" across "15+ platforms" — in which LinkedIn is the most used. You chain "Phantoms" (one task each: extract profiles, enrich, export to a CRM) into workflows, and pay for the execution time they consume: a free plan with 2 hours a month, then 20, 80 or 300 hours. Unlimited users on every plan, an MCP server on every plan, in production since 2016.

Booost Business is a product for one network: outreach, content, publishing and engagement on LinkedIn, on a machine you own, with a safety system built as the product rather than as a setting. No execution meter, no credit meter. €99 per managed account per month, €79 on Basic.

The honest split, in one line: if you want to build your own automations across many platforms, with your whole team on one workspace, PhantomBuster is a better toolbox than Booost will ever be. If you want a finished LinkedIn product that acts from your own hardware, that is Booost. Our limit is stated first.

The limit on our side, first

Booost Business runs while the machine it is installed on is running. PhantomBuster answers the question directly in its FAQ — "Do I need to keep my browser open for a Phantom to run? No. PhantomBuster runs in the cloud." That is a real advantage and it belongs at the top; the section after next explains what we do about it.

What Booost does that PhantomBuster does not

Your session never leaves your machine. Booost signs into LinkedIn the way you do — a browser on your computer, your own connection. We never receive your password, and there is no copy of your session on a server we control. PhantomBuster "runs automations through your own accounts" from its cloud: for that to work, something on their infrastructure must be able to act as you. That is the mechanism, not an accusation.

We are deliberate about the wording: "the session stays local" and "the data stays local" are two different promises, and only the first one is ours — your connection graph does travel to our servers, because that is where the network intelligence below is computed.

Nothing is metered. PhantomBuster's pricing page is a table of meters: execution hours per month, email credits, AI credits, URL-finder credits, automation slots. "Your automations will pause until your execution time resets or you upgrade your plan." Booost has no meter on anything — not on actions, not on AI on the Pro edition, not on the number of accounts the app can manage. The only ceilings are the anti-ban ones, identical on Basic and Pro, and there to keep the account alive rather than to move you up a tier.

It is a product, not a toolbox. PhantomBuster gives you the parts; you assemble the workflow, decide the pacing, and own the result. Booost ships the workflow already assembled for LinkedIn — warm-up over weeks, actions spread across a working day, a brake that engages when LinkedIn's responses change, a diagnostic panel that says which gate stopped an action and why — and a visual builder on top for people who want to change it. PhantomBuster lists "Lead warming" among its features; that is warming a prospect before outreach, a different thing from warming an account.

It maps the network you already have. Booost scores every contact on six axes — thematic fit, seniority, activity, target fit, influence and proximity — each with the evidence behind it, and shows your network as a graph connected by company, school and shared themes. The Strategy tab tracks an affinity score (0–100) for people you want in your network, rising with real interactions and cooling with silence, and can suggest a warm path through a mutual connection and draft the note. PhantomBuster extracts, enriches and builds lists — including from your own connections — and surfaces "intent signals"; it does not score the network you have against goals you set, and nothing in this comparison does.

It publishes, from a pipeline. Booost drafts posts from your own sources — feeds you choose, merged across several outlets — runs each draft through quality gates (a fact-check against the web, a faithfulness check against the source), queues it for your approval, and publishes it under your name or as a Company Page, then reacts, comments and reposts around it. PhantomBuster's pricing page lists LinkedIn outreach campaigns, enrichment and "AI filtering & writing"; publishing posts is not on it, and its comparator is organised by credits rather than by feature, so we state that as not listed, not as absent.

The AI is included flat, or bring your own — including a local model. On Booost Pro, model access is part of the subscription. On Basic, and optionally on Pro, you bring your own key across 20 providers, or run a local model with Ollama. PhantomBuster's AI is metered in credits — 1k on the free plan, 10k, 30k, 90k — which is a fair way to price a toolbox and a strange way to price writing in your own voice.

Built in the EU, GDPR by default, and the desktop app is audited WCAG 2.2 AA.

And Booost Personal is a different product entirely — a browser extension with its own dashboard, for people who want to be present on LinkedIn rather than run campaigns. It reads a post, drafts a comment in your voice in any language, and you publish it. It automates nothing, which is the one compliance claim nobody else in this category can make; it has its own section below. €19–29 per account per month.

"It runs with your browser closed" — so does Booost, on hardware you own

PhantomBuster's FAQ says it in one line, and it is true. The answer is not to concede it but to say precisely what it means.

Booost Business runs while the machine it is installed on is running — and that machine does not have to be your laptop. Every release ships a Linux .deb and an AppImage next to the Windows and macOS builds, and the licence says you may install it on "any device of your own". A small Debian server for a few euros a month qualifies: install it there, leave it on, and campaigns run around the clock.

So both can run 24/7. The difference is whose machine acts as you — theirs or yours — and only one of the two requires a third party to hold something that can log in as you.

One honest gap, documentation rather than architecture: we do not yet publish a step-by-step guide for a headless server, where a desktop application needs a virtual display. It works; the guide is not written yet.

Where PhantomBuster is stronger

1. A real free plan, not a trial. Unlimited users, five automation slots, two hours of execution a month and the MCP server, for nothing. Booost has a trial, not a free tier.
2. Unlimited users on every plan. You pay for the workspace, not for the people in it. Booost prices per managed account; an agency with a team should read the price table below with that in mind.
3. Fifteen platforms, a hundred automations. LinkedIn, Sales Navigator, Google, Instagram, Meta, X — data extraction, enrichment, list-building, scheduled refresh. Booost is one network by choice, and that is a much smaller surface.
4. Integrations and a developer surface. HubSpot, n8n, Zapier, Make, and an MCP server so your AI tools can drive it. Booost has no native CRM integration, webhook, public API or MCP server today — a genuine gap on our side, not a difference of philosophy.
5. Price at scale. The Scale plan is €352 a month for the whole workspace, whatever the number of users or accounts. At twenty-five accounts Booost costs several times that; the arithmetic is below.
6. Maturity. "2.5M+ satisfied users since 2016" on its own page, against a product that opens on 1 September 2026.

Prices, as each company lists them

Read the right-hand column first: these two products are not priced in the same unit at all. PhantomBuster prices the workspace — by execution time, with unlimited users; Booost prices the managed LinkedIn account. PhantomBuster displayed euro prices to us from the EU.

The unit decides the comparison. One person with one LinkedIn account: PhantomBuster Start at €56 is cheaper than Booost Basic at €79, and buys twenty hours of automation a month across fifteen platforms. Twenty-five accounts: PhantomBuster Scale is €352 for all of them; Booost is twenty-five times €79 or €99. If you are choosing on price at volume, PhantomBuster wins that column and we are not going to pretend otherwise. What Booost buys instead is a finished product — no hours to budget, no credits to watch, no pacing to design — on hardware nobody else can act from.

Booost's founding price gives the Pro edition at the Basic price — €79 per account — locked for as long as the subscription stays active: a price that stops moving rather than a discount that expires.

The claim nobody in this category can make — except one

Section 8.2 of LinkedIn's User Agreement prohibits third-party software that automates activity on LinkedIn regardless of where it runs, naming bots, browser plug-ins and browser extensions. Cloud platforms are covered; so are desktop applications; so is Booost Business, and our Acceptable Use Policy says exactly that in writing rather than in small print.

PhantomBuster's FAQ says it "does not use bots, fake accounts, or methods designed to bypass platform safeguards" and "only works with publicly available data accessed through your own accounts". We are not going to turn those sentences against them; the same caution applies to us. Nobody in this category has LinkedIn's permission, and nobody has published comparative restriction rates.

The exception is Booost Personal, and it is the only clean compliance claim in the category: it performs no action on LinkedIn at all. It drafts, a human publishes. No cloud tool can say that, and no other browser extension can either, because both of them act.

How to choose

If you are building your own automations — extraction, enrichment, lists, across several platforms, with a team sharing one workspace and an API or MCP server at the end of it — PhantomBuster is the better toolbox, and this page has told you so. It is also cheaper at volume.

If you want a finished LinkedIn product rather than a kit: warm-up and pacing already designed, content that starts from your sources and passes a fact-check, a map of the people already one step away from you — and all of it acting from a machine you own — that is the product Booost is.

Booost opens on 1 September 2026. Join the waitlist to keep the founding price.
