Dux-Soup vs LinkedHelper: Two Desktop Apps Compared
Two veterans of LinkedIn automation. We compare these legacy tools and show why AI has changed the game.
Dux-Soup and LinkedHelper are two of the oldest LinkedIn automation tools. Dux-Soup now sells STACKED, a desktop app that runs locally or in the cloud, and LinkedHelper is also a desktop app. Both automate profile visits, invitations, and messages. But against modern AI-based solutions, these tools show their limits in personalization and conversion. LinkedHelper starts at $15 a month and Dux-Soup's STACKED at $55 per seat, and both have been around for about a decade. The hidden cost is in the replies: both tools drop prospects into your inbox with no context, and you lose most of the value by not responding fast enough. MimikFlow's Pro plan at $97/month includes the AI Setter that picks up those replies within minutes and moves them toward a Calendly booking.

Where can you read more about each tool?
Where does MimikFlow fit in?
LinkedHelper stays very affordable, and Dux-Soup now starts at $55 per seat with STACKED. But both rely on sequences you build and run yourself. MimikFlow is the next-generation solution: AI-automated prospect search, personalized messages based on individual profile analysis, and a Setter agent that books your Calendly meetings. The higher investment is largely offset by time saved and conversion rates.
FAQ: Dux-Soup vs LinkedHelper
Dux-Soup or LinkedHelper in 2026?
Both rely on sequences you run yourself. If budget is your only constraint, LinkedHelper is far cheaper ($15 a month vs $55 per seat for STACKED Local). But for effective prospecting in 2026, an AI solution like MimikFlow is far more relevant.
Are these tools risky for my LinkedIn account?
Both use automation methods detectable by LinkedIn (desktop apps in both cases, or the cloud with STACKED Cloud). MimikFlow runs in the cloud with limits adapted to your account.
Why is MimikFlow more expensive?
MimikFlow includes advanced AI (search, personalization, conversations, meeting booking) that replaces hours of manual work. At $97/month, it's less than an hour of human setter time per day.
Can I combine Dux-Soup and LinkedHelper?
No, using two automation tools on the same LinkedIn account is very risky. Choose one tool. MimikFlow handles the entire pipeline in a single solution.
Does MimikFlow require a Chrome extension?
No. MimikFlow runs entirely in the cloud via Unipile. No need to keep a browser open or install any extension. Your prospecting runs 24/7.
Can Dux-Soup or LinkedHelper detect an out-of-country prospect?
No. Both tools will happily send a French-language invite to someone based in Mumbai if the search returned them. MimikFlow runs a country filter on every lead source (lead scraper, engagement scraper, invite manager) that maps the prospect's LinkedIn location against your `target_country` setting and drops mismatches before any message goes out. For agencies prospecting a specific market, this alone eliminates a common waste of daily connection budget.
Is there any path from Dux-Soup or LinkedHelper to MimikFlow without losing data?
Both tools store their lead lists locally or in their own cloud. MimikFlow does not have a direct importer for Dux-Soup or LinkedHelper CSVs, but Paid users can paste a list of LinkedIn profile URLs through the 'Import profiles' feature and MimikFlow's pipeline will re-evaluate each profile against your ICP, write a fresh opener, and start outreach. In practice, migrating usually means starting clean and letting the AI re-score your audience.
