Cloud vs browser extension LinkedIn automation: how they differ
Where each design runs, what you hand over, whether your computer has to stay on, how location and teams work, and which risks stay the same either way.
On this page
A browser extension automates LinkedIn from inside your own browser, so it works only while that browser is open. A cloud tool keeps a session to your LinkedIn account on a server and works on its own schedule, with your computer off. Neither design is free of risk: LinkedIn's rules restrict automated tools wherever they run.
The differences that matter when you choose are uptime, what you hand over to connect, where the activity comes from, and how well the tool works for a team. This guide goes through each one. Mako Reach is a cloud tool, so we say where that design is weaker too.
How does a browser extension work?
You install the extension in Chrome or another browser and log in to LinkedIn as usual. The extension acts in your LinkedIn tabs: it opens profiles, clicks Connect, types messages and reads replies, the way you would.
That design has real advantages:
- Nothing leaves your computer to connect. You do not give anyone your LinkedIn login or cookie. The extension uses the session you already have.
- Your usual location. Activity comes from your own computer and internet connection, the same place you use LinkedIn from.
- Quick to start. Install, log in, run.
It also has limits:
- Your computer has to be on. If the laptop sleeps or the browser closes, the campaign stops until you open it again.
- One account per browser profile. Running several LinkedIn accounts means several browser profiles or several computers.
- Hard to share. A colleague cannot read the replies or pick up a conversation without access to your browser.
A desktop app is a close cousin. It runs on your computer outside the browser, so it shares most of these traits.
How does a cloud tool work?
A cloud tool connects to your LinkedIn account from its own servers. You connect once with your LinkedIn login or a session cookie, and the tool then works on a schedule, whether your computer is on or not.
The advantages:
- Runs without you. Campaigns keep their schedule overnight and when your laptop is closed.
- Many accounts in one place. A team or an agency can connect several LinkedIn accounts to one workspace.
- Shared work. Teammates can read replies, answer and pick up conversations from the same screen.
The limits:
- You hand over a credential. Whoever holds your login or session cookie can act as you, so ask how the vendor stores it.
- Activity comes from somewhere else. Unless the tool routes it through a proxy, LinkedIn sees activity from a data centre instead of from your usual location. Ask what proxy the tool uses and in which country.
- Setup takes a minute longer. Connecting can involve a code from LinkedIn the first time.
Side by side
| Question | Browser extension | Cloud tool |
|---|---|---|
| Where does it run? | In your browser, on your computer | On the vendor's servers |
| Must your computer stay on? | Yes | No |
| What do you hand over? | Nothing beyond the extension's permissions | A LinkedIn login or session cookie |
| Where does activity come from? | Your own connection | The vendor's servers, usually through a proxy |
| Several LinkedIn accounts? | One per browser profile | Many in one workspace |
| Team access to replies? | Hard | Usually built in |
| Restricted by LinkedIn's rules? | Yes | Yes |
Which risks are the same either way?
LinkedIn's Help page on prohibited software and extensions says LinkedIn does not permit third-party software, including bots and browser extensions, that scrapes, changes the look of or automates activity on its website. That covers both designs. Choosing one over the other does not take you outside the rule.
What you control is how the account behaves. In our view, three things matter more than where the tool runs:
- Volume. How many invitations and messages go out a day and a week. Our guide to LinkedIn limits in 2026 collects what sources say.
- How people react. Invitations that are ignored or reported, and messages nobody wants, are worse signals than any tool choice.
- Steadiness. Sudden jumps in activity from an account that was quiet for months.
A tool can help with the first and third points by enforcing caps. The second one depends on who you contact and what you write.
Which design fits whom?
A browser extension fits one person who runs a small campaign from their own account, works at their desk most days and prefers not to hand a credential to a vendor.
A cloud tool fits a sales team or an agency with several accounts, campaigns that should run on a schedule, and replies that more than one person reads.
If you run both on the same account, the two tools do not know about each other's activity, so neither can keep you under your own daily caps. Pick one tool per account.
How Mako Reach does it
Mako Reach runs in the cloud. There is no extension to install or keep open.
- You connect each LinkedIn account with its own login or cookie. Credentials are encrypted before they reach the database.
- Each account has a proxy in a country you choose.
- Each account has daily caps that the engine enforces: 28 invitations and 40 messages a day by default, adjustable from 0 to 100 per action. When a cap is reached, sending stops for that account until the next day.
- Replies from every account arrive in one inbox, and teammates see only the accounts you give them.
None of this removes the risk. Mako Reach is not affiliated with LinkedIn, and no tool can promise that an account will not be restricted. Read more on the account safety page.
Questions to ask any vendor
- Does it run in my browser, on my computer or on your servers?
- What do I hand over to connect an account, and how is it stored?
- Where does the activity come from? Is there a proxy, and in which country?
- Are daily limits enforced by the engine or only suggested?
- Can several people work on several accounts, with access to only some of them?
- What does the vendor say about LinkedIn's rules?
The buyer's checklist has more questions to ask before you choose.
FAQ
Is a cloud tool safer than a browser extension?
Neither design is free of risk. LinkedIn's Help says it does not permit third-party software that automates activity, whether it runs in a browser or elsewhere. The differences are practical: uptime, what you hand over, where activity comes from and team access.
Does a cloud tool need my LinkedIn password?
It needs either your login or a session cookie from a browser where you are logged in. Ask how the vendor stores it. Mako Reach encrypts credentials before they reach the database.
Does LinkedIn allow browser extensions?
Not ones that automate activity. LinkedIn's Help page on prohibited software and extensions names browser extensions that scrape, change the look of or automate activity on its website.
Can I use an extension and a cloud tool on the same account?
You can, but neither tool sees the other's activity, so your real daily volume is the sum of both and no single cap applies. Use one tool per account.
Does Mako Reach have a Chrome extension?
No. Mako Reach runs in the cloud and needs nothing installed in your browser.
