The short answer
Linked Helper is a desktop application — "Desktop app, not a Chrome extension", on its own home page — that has automated LinkedIn outreach for seven years across "180 out of the 195 sovereign states". It runs on your machine, recommends one proxy per account, enforces "Smart daily limits", and has built-in AI for messages, comments and lead qualification, metered in credits. Standard is $29.90 a month, or $16.50 a month on a twelve-month plan; Pro $59.90, or $33.
Booost Business is also a desktop application: your LinkedIn session stays on a machine you own. It does outreach and content in one workflow, scores the network you already have, and puts no quota on what you may send. €99 per managed account per month, €79 on Basic.
This is one of two comparisons on this site where the architecture argument does not apply. We agree with Linked Helper about where a LinkedIn tool should run. So the honest split is about the rest, and it starts with the number: Linked Helper costs a fraction of Booost. If outreach from your own machine is the whole job, buy Linked Helper. What follows is what the difference buys, for readers who need more than outreach.
The price, first
On a yearly plan, Linked Helper Standard is $16.50 a month and Pro is $33. Booost Business is €79 to €99 per managed account. Nothing on this page makes that gap smaller, and we are not going to write it at the bottom.
Same side of the line — and what still differs
Both products sign into LinkedIn from a browser on your computer, on your connection, with no third party holding a session that can act as you. Section 8.2 of LinkedIn's User Agreement covers both of us all the same, and our Acceptable Use Policy says so in writing.
Three things differ inside that shared architecture:
- Proxies. Linked Helper's home page says "One proxy. One account — Dedicated IP per profile keeps footprints clean and isolated", with a "built-in proxy health check". Booost takes the opposite position: the IP LinkedIn sees is the one you already have, and the app does not route anything through a third-party address. Which is safer is not something either of us can prove; it is a design choice, and you should know which one you are buying.
- Sessions. Linked Helper licenses "1 license = 1 LinkedIn account" and a license "can't be used on two accounts simultaneously". Booost manages several accounts from one installation, each in its own isolated browser session, each with its own warm-up state and safety counters.
- Data. The prices on Linked Helper's pricing page on 22 August 2026 are for its "Cloud-based storage version" — your data is "automatically backed up to the cloud". Booost keeps your data on the machine, with one exception we say plainly: your connection graph travels to our servers, because that is where the network intelligence below is computed. "The session stays local" is our promise; "the data stays local" is only partly ours.
What Booost does that Linked Helper does not
Your limits are set by safety, not by your plan. Linked Helper's Standard plan caps "advanced actions" at 20 a day — 20 messages to group members or event attendees, 20 likes, 20 invitations to follow your page — and "Unlimited daily actions" is the Pro feature. Booost has no plan quota on any edition: 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. Nobody at Booost sells you permission to go faster.
It publishes. 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, a "does this read like a machine" check), queues it for your approval, and publishes it under your name or as a Company Page, then reacts, comments and reposts around it in the same workflow as the outreach. Linked Helper likes and comments posts, and its AI writes comments on prospects' posts to warm them before a message; publishing posts is not on its feature list. We state that as not listed.
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. Linked Helper's "AI ICP Detection" checks each collected profile against the customer profile you describe — a filter on a list. It is the closest thing to this in the comparison, and it is a different thing.
The AI is flat, or yours — not metered. Linked Helper's AI is metered: 250 AI credits a month on Standard, 500 on Pro, "can be purchased separately if needed". 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 so nothing leaves the machine at all — which, for a product whose whole argument is "your machine", is the version of AI that matches.
The warm-up is measurable, not a setting. Both products pace actions, randomise delays and cap days; Linked Helper says so on its home page and we are not going to pretend it does not. What Booost adds is a safety system you can inspect: a warm-up over weeks that gates reads as well as writes, a circuit breaker that opens when LinkedIn's responses change, an anomaly detector for robotic timing, and a diagnostic panel that says which gate stopped an action and why. Neither of us can prove whose account survives longer; we can show you ours.
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.
Where Linked Helper is stronger
- Price. $16.50 to $59.90 a month against €79 to €99. This is the first line of the page and it belongs in this list too.
- Seven years in production. "For the last 7 years", "10,000 businesses", "180 out of the 195 sovereign states". Booost opens on 1 September 2026.
- More LinkedIn actions. InMails, messages to group members and event attendees, invitations to events, to your Company Page and to groups, endorsements, removing unwanted connections. Booost does not do InMail, groups, events or endorsements today — a genuine gap on our side.
- Webhooks and data. Outgoing and incoming webhooks to Zapier, Make and CRMs (20 profiles a day on Standard, unlimited on Pro), and contact enrichment with emails and phones on data credits. Booost has no webhook, no public API and no email enrichment today.
- Published guides for running on your own server. Linked Helper's support centre has step-by-step articles for installing it on a Windows VPS and on an Ubuntu server; Booost's headless-server guide is not written yet, although the licence already allows it and the Linux builds already ship.
- Proxies built in, if that is what you want. A proxy per account with a health check in the launcher. Booost deliberately does not do this; if you have decided you want a dedicated IP, Linked Helper has the feature and we do not.
Prices, as each company lists them
Read the right-hand column first. Linked Helper prices per license, one LinkedIn account at a time; Booost per managed account. Linked Helper's monthly price falls with the term: 11% off at three months, 33% at six, 45% at twelve.
| monthly | what it buys | |
|---|---|---|
| Linked Helper Standard | $29.90 · $16.50 on a 12-month plan | unlimited campaigns, CRM with tags and notes, CSV export; advanced actions capped at 20 a day; webhooks 20 profiles a day; 620 data credits; AI credits |
| Linked Helper Pro | $59.90 · $33 on a 12-month plan | unlimited daily actions, unlimited webhooks, advanced export, 3,100 data credits, more AI credits |
| Booost Business Basic | €79 · €899/year | per managed account; the whole platform, no quota: outreach, content pipeline, publishing as you or as a Company Page, AI inbox, network intelligence — with your own AI key |
| Booost Business Pro | €99 · €999/year | the same, plus Booost's managed AI and every workflow node |
Currencies are left as each company publishes them: converting them produces a table that goes wrong on its own when the rate moves.
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. It does not close the gap with Linked Helper, and we do not claim it does.
The claim nobody in this category can make — except one
Linked Helper's home page calls itself "The Safest LinkedIn Automation Tool", and adds a design reason: "No code injected into the LinkedIn page". We will not argue with either sentence. Nobody — us included — can honestly claim LinkedIn's approval; Section 8.2 covers desktop applications as much as extensions and clouds; and nobody has published data comparing restriction rates between tools. Argue about the mechanism, which is checkable.
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 what you need is outreach from your own machine — invitations, sequences, InMails, group and event messaging, enrichment, webhooks — Linked Helper does that job, has done it for seven years, and costs a fraction of Booost. This page has told you so in its first paragraph.
If you need the tool to build your presence as well as your pipeline — content from your sources that passes a fact-check, published as you or as your Company Page — and a map of the people already one step away from you, with AI that is flat or runs on your own hardware, that is the product Booost is, and it is the reason the price is different.
Booost opens on 1 September 2026. Join the waitlist to keep the founding price.
