Most people start comparing LinkedIn automation tools by lining up feature lists side by side. That’s usually the wrong place to start. Two questions tend to matter more: where does the automation actually run, and how does a message actually get written? Everything else, safety, pricing, day-to-day reliability, tends to follow from the answers to those two.
Dux-Soup and Linkyfy both automate LinkedIn outreach, but they answer those questions differently. Dux-Soup gives you a choice: run it as a desktop app on your own machine, or move it to its own cloud infrastructure instead. Linkyfy doesn’t offer that choice, because every plan already runs entirely in the cloud, with no local install and nothing that needs to stay powered on.
That single difference in where the tool runs ends up shaping most of what separates them elsewhere: how AI personalization actually works, what account safety looks like day to day, and how each company structures its pricing. This guide compares both tools on features, safety, and real cost, without leaning on which one has simply been around longer.
Linkyfy vs Dux-Soup at a Quick Overview
| Factor | Linkyfy | Dux-Soup |
|---|---|---|
| Best for | Founders, CXOs, and lean sales teams focused on LinkedIn | Solo users and CRM-heavy teams comfortable managing a local or cloud setup |
| How it runs | Fully cloud-based, no local install on any plan | STACKED Local (desktop app on your machine) or STACKED Cloud (hosted on their infrastructure) |
| AI personalization | Unique message per prospect, generated from profile and company data as the core mechanism | AI personalization layered on top of drip-campaign templates |
| Account safety | Dedicated IP (Standard plan+), daily caps, randomized pacing, eligibility checks | Activity throttling and daily limits; risk profile depends on which deployment you pick |
| Multi-account / agency use | Up to 3 LinkedIn accounts on one Business Plus plan | Per-seat pricing, no built-in multi-account bundling |
| Pricing model | Flat monthly tiers | Two flat tiers: Local and Cloud |
| Starting price | Free plan, paid from $39/month | From 41.25/month billed annually (55/month billed monthly) |
What Is Linkyfy?
Linkyfy is a cloud-first LinkedIn and email outreach platform, built around the idea that personalization should come from real signals rather than a fill-in-the-blank script. Every plan runs entirely on Linkyfy’s own servers, so there’s nothing to install locally and no computer that has to stay switched on for a campaign to keep moving.
Before a message goes out, Linkyfy pulls in the prospect’s role, company, and recent activity, then writes something specific to that person instead of dropping a first name into a shared template. Accounts go through an eligibility check before they’re allowed to run a campaign at all, and daily sending volume stays capped and randomly timed rather than fixed to one flat number.
It tends to fit best for founders, CXOs, and small sales teams who want LinkedIn outreach that reads like it was actually written for the recipient, without also taking on a separate tool to manage where or how that automation runs.
What Is Dux-Soup?
Dux-Soup is a LinkedIn automation tool offering two ways to run campaigns. STACKED Local is a desktop application for Mac or Windows that runs on your own machine. STACKED Cloud runs on Dux-Soup’s own infrastructure instead, so a campaign keeps going without a local machine staying online. Both versions handle connection requests, profile visits, drip campaigns, and tagging, and both sync two-way with CRMs like HubSpot, Salesforce, and Pipedrive. Dux-Soup has also added AI-powered personalization on top of its existing campaign structure.
It’s built for users who are comfortable choosing between a local or hosted setup, and for teams that lean heavily on CRM integration as part of their workflow.
Key Differences Compared
Architecture: Desktop-Dependent vs. Fully Cloud
This is the starting point for almost everything else in this comparison. Dux-Soup’s STACKED Local runs on your own computer, so campaigns depend on that machine staying on and connected. Its STACKED Cloud tier removes that dependency, but it’s a separate, higher-priced plan rather than the default.
Linkyfy skips that choice entirely. Every plan runs in the cloud, so there’s no local install, no browser extension, and no device that needs to stay powered on for a campaign to keep running.
AI Personalization: Layered On vs. Built In
Dux-Soup added AI personalization as a feature on top of a campaign structure that was already built around templates and drip sequences. That’s a real improvement over static variables, but the underlying structure is still template-first.
Linkyfy works the other way around. Every message gets generated from scratch, per prospect, using their profile, role, company, and recent activity as the input. There’s no shared template sitting underneath it. As a result, personalization isn’t an add-on layer, it’s the core mechanism the message is built from.
Integrations and Workflow Fit
Dux-Soup’s CRM integrations are a genuine strength, with two-way sync into HubSpot, Salesforce, and Pipedrive built directly into the product. Teams that already run their pipeline through one of those tools get a tight, direct connection.
Linkyfy takes a narrower approach on purpose. It includes a built-in email finder and standard CRM sync, but it doesn’t try to be a full data-sync layer. Instead, it puts that effort into the outreach and personalization side of the workflow.
Pricing Structure and Real Cost
Dux-Soup keeps pricing simple with two tiers: STACKED Local and STACKED Cloud, each with a flat monthly and annual rate. There’s no execution-hour or credit system to track, which makes cost predictable regardless of which deployment you choose.
Linkyfy’s pricing is also flat and published in full, spread across four tiers instead of two, with the top tier adding multi-account support for agencies. Neither tool hides pricing behind a “contact sales” wall at the entry level, so this comparison comes down to which tier structure actually matches how you plan to use it.
Pricing Compared
| Plan | Linkyfy | Dux-Soup |
|---|---|---|
| Free | 1 LinkedIn account, 20 invites and 20 profile fetches a day | Not available |
| Entry tier | Standard, $39/month | STACKED Local, $55/month ($41.25/month billed annually) |
| Mid tier | Business, $69/month | STACKED Cloud, $99/month ($74.17/month billed annually) |
| Top tier | Business Plus, $149/month (up to 3 LinkedIn accounts) | Not available |

Modern, Cloud-Native LinkedIn Outreach With Linkyfy
Dux-Soup gives you a choice between running automation on your own machine or paying more to move it to the cloud. Linkyfy skips that decision by building every plan cloud-first from the start, so personalization, safety checks, and message generation all run the same way regardless of which tier you’re on. If your priority is AI-generated, per-prospect messaging without managing where the automation actually runs, Linkyfy’s LinkedIn outreach automation is built for exactly that, with a free plan to test it first.
