Cloud LinkedIn Automation vs Chrome Extensions: Four Architectures
A Chrome extension costs little and keeps your login on your own laptop, and it stops when the laptop does. A cloud tool keeps going all night, with your account signed in on a server you don’t run.
LinkedIn automation runs in one of four places: an extension in your own Chrome, a desktop app on your computer, a cloud app that runs your account on the vendor’s servers, or an API that your code or an AI agent calls. The first two keep your login on your own machine and stop when it does. The last two run around the clock, at whatever daily limits and pace the vendor or your code sets.

The four architectures side by side
LinkedIn automation software comes in these four shapes, and what separates them is where the account’s LinkedIn session lives, because that decides who keeps a machine running and who sets the pace. An extension and a desktop app keep the session on your computer. A cloud app keeps it on the vendor’s servers. An API is a way to drive an account from code, and the session behind it usually sits on the vendor’s servers too.
| Architecture | Where the session lives | What it needs from you | When it runs | Entry price a month | Limits and pacing risk | Examples |
|---|---|---|---|---|---|---|
| On your own computer | ||||||
| Browser extension | Your own Chrome, signed in as you | Chrome open, the computer awake, one Chrome profile per account | While the browser is open | Per user: Octopus CRM $9.99, OutX free plan or $99 | The day’s actions fit into your hours, and your own clicks spend the same limits | Octopus CRM, OutX |
| Desktop app | An app on your Mac or PC, or on a server you rent | The app installed and running, the machine switched on | While the app runs | Per licence or seat: Linked Helper $15, Dux-Soup STACKED local $55, plus the machine | On a laptop, the extension’s hours. The caps are whatever you type in | Linked Helper, Dux-Soup STACKED local |
| On the vendor’s servers | ||||||
| Cloud app | On the vendor’s servers, in a browser kept for each account where the vendor publishes one | A sign-in (or cookies or a password, by vendor), a proxy country, working hours | Around the clock, inside the hours you set | Per seat or account, browser and proxy usually included: gtm-api.com free for one account, then from $10/account. Linked API $69, Dripify $79, Expandi $99 | Runs at night unless hours are set. The vendor’s caps and gaps set the pace, and your other sessions spend the same limits | gtm-api.com and Linked API publish a browser per account. Dripify, Expandi and Woodpecker say cloud |
| API | Usually on the vendor’s servers. OutX’s API runs through its extension | An API key or OAuth, code or an AI agent to call it, one sign-in per account | Whenever it is called | Per account or per credit: gtm-api.com free for one account, then from $10/account. Unipile €49 for up to 10 accounts, LinkupAPI $55 for up to 10, Edges $7.99 per identity | Sends as fast as it is called, unless the server holds a daily budget and a gap between calls | gtm-api.com, Linked API, Unipile, LinkupAPI, Edges |
Prices are entry prices per month on monthly billing, read on each vendor’s pricing page on 14 and 15 October 2026 and re-checked on 24 October. Some vendors sit in two rows: Dux-Soup sells a desktop and a cloud version of one product, lemlist connects LinkedIn through a Chrome extension inside its web app, and OutX sells an API that works through its extension. Whether automation is safe at all, and what gets an account restricted, is covered in the safe LinkedIn automation guide. This page compares where tools run. How the category runs as a whole, its costs and its rules are on the LinkedIn automation hub.
Browser extension: automation inside your own Chrome
A browser extension adds automation to the Chrome you already use and acts through the LinkedIn session you are signed in with. You hand nothing over: Octopus CRM says it will “never ask for your LinkedIn credentials”. OutX’s documentation puts the model in one line: “OutX runs through the Chrome extension installed on your browser.”
What it needs is a running browser: the computer awake, Chrome open, and the right account signed in on that Chrome profile. OutX ties even its API to this, and its docs say API calls work only while someone on the team has had the extension active within the last 48 hours. Some web apps connect LinkedIn the same way: lemlist’s help center says its LinkedIn actions “depend on the correct browser session (cookies + the Chrome extension)”, and its guide to a second LinkedIn profile uses a separate lemlist seat and a separate Chrome profile.
Extensions sit at the low end of the price range because your laptop is the infrastructure. Octopus CRM starts at $9.99 a month, and OutX has a free plan next to paid plans from $99 a month.
The risk sits in the clock and in the shared session:
- The day fits into your hours. Nothing runs while the laptop is closed, so the day’s actions go out while you are at your desk. Fewer hours at the computer means fewer actions, or shorter gaps between them.
- You and the tool share one session. What you do by hand and what the extension does go out from the same signed-in browser and count against the same LinkedIn limits.
- Each account needs its own browser. A second LinkedIn account means a second Chrome profile signed in as that account, on a machine that stays awake for both.
One vendor left this row in 2026. Waalaxy wrote on 1 July 2026 that it “is now 100% cloud” and that its Chrome extension “has been removed from the Chrome Web Store”.
Desktop app: automation on a machine you run
A desktop app installs on a Mac or a PC and drives LinkedIn from there, with the session kept on that machine. Linked Helper’s pricing page spells the model out: it is “desktop software on both versions”, the automation runs “On your own computer or VPS”, and the LinkedIn session lives “On that same machine”, “never on our servers”.
It needs the app installed, the app running and the machine switched on. Put it on a rented server (a VPS) and it keeps working overnight, with the session moved to that server. Dux-Soup now sells both shapes of one product: STACKED local, which “Runs on your own machine”, and STACKED cloud, which “Runs on our infrastructure, managed & monitored”.
Linked Helper starts at $15 a month per licence on a one-month term, and Dux-Soup’s STACKED local at $55 a month per seat, against $99 for STACKED cloud. The computer or the server it runs on is your cost on top.
- Same clock as the machine. On a laptop the app stops when the lid closes, exactly like an extension. On a server it runs as long as you let it, so working hours become a setting you have to make.
- The caps are yours to type. A desktop app sends what its settings allow, so a new account given a seasoned account’s daily numbers sends them. Set a new or quiet account well below an old one, and raise it over weeks.
Cloud app: the session on the vendor’s servers
A cloud-based LinkedIn automation tool runs on the vendor’s servers, so the account keeps working with your laptop shut. Dripify says its campaigns “run on our servers, so nothing depends on your browser being open or your machine being on”, and Woodpecker says of its LinkedIn steps that “the actions will happen even if you turn off your computer”.
A browser per account
Most cloud apps say “cloud” and stop there. A few say what holds the session. Linked API writes that “Each LinkedIn account gets its own full browser in the cloud”, and GTM API runs every connected account in exactly one cloud browser kept for it. The practical reason to care is the sign-in: with a browser per account you log in to LinkedIn yourself, inside that browser, and the password never passes through the vendor. Linked API puts it as “We never see, intercept, or store your password”. Other cloud apps take the session another way. HeyReach connects an account either with cookies exported from your browser or with your LinkedIn email and password.
A browser on a server also needs an address to send from, which is where the proxy comes in. GTM API attaches a proxy in the country you pick when you connect the account, and its docs ask for the country the account normally works from. Dripify assigns a dedicated IP “tied to your account, in your location”. HeyReach includes a residential proxy per sender on its entry plan, and its Agency and Unlimited plans “require you to bring your own proxies”.
So a cloud app asks you for a sign-in (or your cookies or password, depending on the vendor), a proxy country or a proxy of your own, and working hours. Expandi lists the last one at setup: “you will need to set your timezone, active days, and hours for when your profile will be running and sending”.
Cloud apps charge per seat, sender or connected account, and the browser and the proxy usually sit inside that price. Read on 14 October 2026:
- gtm-api.com: a free plan for one account, then from $10/account, with a cloud browser and a residential proxy per account included and API calls and actions not metered.
- Linked API: $69 a seat a month, or $49 billed annually, one seat per connected account.
- Dripify: $79 a seat a month on Pro.
- Expandi: $99 a seat a month on Business.
- Woodpecker: $29 a month per connected LinkedIn account, on its own LinkedIn plan or added to an email plan priced by emails sent.
The risk moves from your clock to the vendor’s settings:
- It runs at night unless you set hours. The account works whenever the scheduler has work, so check the working hours on the first day. Expandi asks for them at setup, and Woodpecker sends “within fixed hours between 8 AM and 6 PM” on weekdays. On GTM API the per-account window (Monday to Friday, 09:00 to 18:00 by default) schedules recurring syncs, and sends go out whenever you or your automation trigger them, under the account’s daily budgets.
- The vendor’s defaults are the pace. Daily caps, the gap between actions and the warm-up for a new account start as the vendor’s numbers. Read them, and lower them for an account that is new or has been quiet.
- Your other sessions still count. Opening LinkedIn on your phone while the cloud browser works means two places act on one account, and the vendor’s counter sees only its own half.
API: automation your code or an AI agent drives
An API gives you the actions themselves (send a connection request, read a thread, reply) and leaves the plan to your code, to a workflow tool such as n8n, or to an AI agent through an MCP server. It is a way to drive an account, and the session still lives somewhere: Linked API and GTM API run a cloud browser per account, LinkupAPI describes itself as “100% cloud-based”, and OutX’s API works through the extension in your browser.
It needs an API key, or an OAuth sign-in for an AI client, something that makes the calls, and one LinkedIn sign-in per account. On GTM API that sign-in happens once, in the account’s cloud browser, and the hosted MCP server takes either OAuth or the API key as a bearer token, so Claude, Cursor or your own script can drive the same account.
APIs charge per connected account or per credit, and the campaign logic is yours to build. Read on 14 October 2026:
- gtm-api.com: the same per-account price as in the cloud row, free for one account, then from $10/account.
- Unipile: a €49 monthly minimum that covers up to 10 connected accounts.
- LinkupAPI: $55 a month flat for up to 10 connected accounts, with “No credits, no per-call fees”.
- Edges: $7.99 per identity a month, down to $3.82 at volume, with data credits on a separate meter.
An API sends as fast as it is called. An agent in a loop, a workflow that retries or a backfill script can spend a day’s budget in minutes, so the question for any API is where its limits live:
- On the server. GTM API checks a daily budget per action before every call, sends calls of one kind one at a time with the gap varied by up to 20%, and parks work that would go over the budget until it refreshes. Edges states that “Per-identity rate limits are enforced in our infra.”
- In your code. Where an API publishes recommended numbers and leaves enforcement to the caller, the daily caps, the gaps and the working hours are code you write and test.
- In the schedule. An API sends when it is called, so an agent that runs at 3 AM sends at 3 AM unless something on the server holds working hours for the account.
What an automation API does, costs and enforces is on LinkedIn automation API, builder criteria for choosing one are on best LinkedIn API, and connecting an agent is covered on LinkedIn MCP server.
Two tools on one account
LinkedIn’s limits belong to the account, so every architecture on this page draws on the same allowance, and a tool’s daily counter covers what that tool sent. Edges says so about its own counter: “Edges counts only the actions performed through the platform. Activity done by hand on LinkedIn, or through another tool, is invisible to us and still counts against the account with LinkedIn.”
That makes mixed setups the case to plan for:
- An extension next to a cloud app. Two schedulers spend one allowance, and neither sees the other’s sends.
- Manual work next to any tool. Invitations you send from your phone come out of the same weekly allowance the tool is budgeting.
If two tools have to share an account, set each one’s daily caps so the two together stay under the account’s budget, with room left for what you do by hand. The weekly invitation numbers are on LinkedIn connection limits, and the LinkedIn limits calculator turns an account’s age and plan into a daily plan per action. Running several accounts of your own is its own topic, covered in scaling LinkedIn automation.
How to tell which one a tool is
Vendors seldom name their architecture, so read the help center and the pricing FAQ for these phrases:
- “Chrome Web Store”, “install the extension”. An extension. Octopus CRM’s free-trial link goes to its Chrome Web Store listing.
- “Desktop app”, “Mac/Win”, “your own computer or VPS”. A desktop app, as with Linked Helper and Dux-Soup’s STACKED local.
- “Runs on our servers”, “even if you turn off your computer”. A cloud app. Then look for what holds the session and what the vendor asks for at sign-in.
- “API key”, “MCP server”, “per connected account”. An API. Ask where its sessions run, because the answer is one of the other three rows.
- None of these. Some vendors don’t say. AiSDR and Sonarly, on the pages we read on 14 October 2026, sell LinkedIn accounts as part of a plan without saying where the actions run. Ask in writing before you connect an account.
Which one fits your setup
Pick by how many accounts you run, when they should work and what drives them:
- One account, a few actions a day, while you are at your desk. An extension or a desktop app covers it for little money, as long as the day’s work fits into the hours your computer is on. A free API plan is the other route: GTM API’s covers one account with daily caps and no card.
- An account that should work while you sleep, or several of them. A cloud app. Before you connect anything, check what it asks for at sign-in, which hours it sends in and the caps per account.
- A product, a workflow or an AI agent of your own. An API, and one that holds the daily budget and the gaps on the server, so a loop in your code can’t spend the account’s day. GTM API is built for this case, with a REST API and an MCP server on one contract.
Frequently Asked Questions
Is cloud LinkedIn automation safer than a Chrome extension?
The architecture alone doesn’t decide it, and LinkedIn’s User Agreement prohibits automated access whichever one sends. What changes is who sets the pace. An extension acts only while your browser is open, so the day’s actions squeeze into your working hours and share one session with your own clicks. A cloud app runs on the vendor’s servers around the clock, so its daily caps, its gaps between actions and its working hours are the vendor’s settings until you change them. Pick the tool whose limits you can read and set.
Do I need to keep my computer on for LinkedIn automation?
Only with a browser extension or a desktop app, because both act from your own machine. An extension needs Chrome open and the computer awake, and a desktop app such as Linked Helper needs the app running, on your computer or on a server you rent. Cloud apps and APIs run on the vendor’s servers. Dripify says nothing “depends on your browser being open or your machine being on”, and GTM API runs each account in a cloud browser of its own.
Does a cloud LinkedIn automation tool need my LinkedIn password?
It depends on how the vendor holds the session. HeyReach connects an account with cookies exported from your browser or with your LinkedIn email and password. Tools that run a browser per account have you sign in yourself, inside that browser: Linked API says “We never see, intercept, or store your password”, and on GTM API the login happens in the account’s own cloud browser, so the password stays with you. A Chrome extension uses the session already open in your browser.
How much does cloud LinkedIn automation cost?
Most cloud apps charge per seat or connected account each month, usually with the browser and the proxy included. GTM API, our product, is free for one account and then from $10/account. Among the others, read on 14 October 2026: Dripify charges $79 a seat on Pro, Expandi $99 a seat on Business, Linked API $69 a seat ($49 billed annually), and Woodpecker $29 per LinkedIn account a month. Extensions charge per user and run on your own computer: Octopus CRM starts at $9.99 a month.
Can I run a Chrome extension and a cloud tool on the same LinkedIn account?
You can, and both spend from one allowance. LinkedIn’s limits belong to the account, and each tool counts only what it sent, so two schedulers can each stay inside their own caps while the account goes over. Edges says as much about its own counter: activity “through another tool, is invisible to us and still counts against the account with LinkedIn”. If you run two, set their daily caps so together they stay under the account’s budget, and leave room for what you do by hand.
