Comparison
Dux-Soup and Linked Helper are both veteran LinkedIn automation tools and both predate the cloud-platform generation by years. They compete for the same user — the power operator who wants deep control — but they take opposite technical paths. Dux-Soup is a Chrome extension. Linked Helper is a desktop application. This guide compares them honestly on configurability, pricing, integrations, and architecture.
Dux-Soup wins on ease of install, broader CRM integration catalog, brand recognition, and a genuine free tier. Linked Helper wins on raw configurability, scenario depth (the workflow editor is the most powerful in the comparison), and one-time license pricing that is cheaper long-term. Choose Dux-Soup if you want a polished Chrome extension. Choose Linked Helper if you are a power user who wants maximum control.
Capability-by-capability comparison across the dimensions that decide a 2026 LinkedIn outreach buying decision.
| Capability | Dux-Soup | Linked Helper |
|---|---|---|
| Architecture | Chrome extension | Desktop application |

| CRM integration catalog | Broad native catalog | Narrower, more webhook-based |
| Cloud sending (laptop off) | No (extension) | No (desktop app) |
| Multi-account | One per browser profile | License per account |
| UI / modernness | Older but polished | Powerful, dated UI |
| Community size | Largest in category | Smaller, power-user heavy |

Every comparison page should name a dimension where each tool wins. Otherwise it is not a comparison; it is marketing.
The original LinkedIn Chrome extension — install base, integration depth, and a free tier.
Dux-Soup installs from the Chrome Web Store in under a minute. Linked Helper is a desktop application that you download, install, and configure with elevated permissions. For non-technical users, Dux-Soup wins on time-to-first-action substantially.
After a decade of customer pressure, Dux-Soup has direct native integrations with HubSpot, Pipedrive, Salesforce, Zoho, and many more. Linked Helper has integrations too but the catalog is narrower and several flow through Zapier or webhook configuration.
Dux-Soup has a free plan for basic profile visits — useful for sampling the extension before committing. Linked Helper offers a free trial but no permanent free tier.
Dux-Soup launched in 2015 and has the largest install base in LinkedIn automation. The community forums, tutorial library, and known-edge-case documentation are deeper than Linked Helper.
Desktop application with the most configurable workflow editor in the LinkedIn automation category.
Linked Helper scenarios let you chain almost any LinkedIn action with conditions, branches, time windows, and custom data fields. If you can describe a workflow, you can probably build it in Linked Helper. Dux-Soup is simpler and intentionally less configurable.
Linked Helper offers a one-time license per LinkedIn account (with optional annual updates). Over 2-3 years, Linked Helper is materially cheaper than a Dux-Soup subscription for the same coverage. The upfront cost is higher; the ongoing cost is lower.
Because Linked Helper runs as a desktop app on your machine, LinkedIn sees a normal browser session with your real cookies and IP. Some operators argue this is safer than Chrome extension automation. Others argue the opposite. The truth is both can get your account restricted if you push past limits.
Linked Helper exposes settings — daily caps per action type, randomization windows, custom field mappings, post-action delays — that Dux-Soup either hides or does not expose at all. For power users this depth is the entire reason to pick it.
On day one Dux-Soup is cheaper — the free tier and low entry subscription make it accessible. Over a 2-3 year horizon, Linked Helper is materially cheaper because the one-time license amortizes well versus an ongoing subscription. For users running multiple LinkedIn accounts, the math gets more complicated: Linked Helper needs a license per account, Dux-Soup needs a separate Chrome profile per account. Neither tool is cheap if you are running an agency with 10 senders — for that scale, cloud platforms like HeyReach or LinkedNav are economically dominant.
Subscription tiered by feature set. Genuine free tier; entry paid tier is low.
One-time license per LinkedIn account (or annual). Materially cheaper long-term than Dux-Soup subscription.
A short decision tree based on team shape, budget, and what you actually need the tool to do.
Choose Dux-Soup if you want the easiest possible install (Chrome extension), you value the broadest native CRM integration catalog, you need a genuine free tier to sample the tool, or you prefer a polished UI over raw configurability. Dux-Soup is also the safer pick for non-technical users.
Choose Linked Helper if you are a power user who wants the most configurable workflow editor in the category, you value one-time license economics over ongoing subscription, you prefer running automation as a desktop app on your own machine, or you need scenario depth that Dux-Soup intentionally does not expose.
Pick neither if your real problem is multi-sender outreach (both tools require browser sessions per account, which does not scale), verified email enrichment at scale, buying-signal monitoring, or campaigns run by an AI agent. Both Dux-Soup and Linked Helper are single-user tools by architecture.
There is a different shape of tool worth considering. Both Dux-Soup and Linked Helper are local-machine tools — your browser or desktop app has to be running for campaigns to send. That architecture worked in 2018 and still works for solo operators. In 2026 most growing teams move to cloud platforms because they want campaigns running with laptops closed, multiple senders managed from one dashboard, and modern features like buying-signal monitoring and AI reply drafts. LinkedNav is the cloud alternative most ex-Dux-Soup and ex-Linked Helper users pick. It is cloud multi-sender (so campaigns run 24/7), it has native email enrichment in the same workflow, it monitors buying signals, and it ships with a native MCP server at mcp.linkednav.com so Claude can build and run campaigns end-to-end. For power users who want the configurability of Linked Helper without the desktop-app constraint, or the ease of Dux-Soup without the extension constraint, LinkedNav is usually the next stop.
Long-term, yes. Linked Helper offers a one-time license per LinkedIn account that amortizes well over 2-3 years versus a Dux-Soup subscription. On day one Dux-Soup is cheaper. Over a multi-year horizon Linked Helper wins on total cost.
Dux-Soup has the broader native CRM integration catalog after a decade of refinement. Linked Helper supports the major CRMs but several flow through webhooks or Zapier rather than native. For niche CRMs, Dux-Soup is the safer bet.
Both architectures have produced LinkedIn restrictions. What actually moves the safety needle is daily cap configuration, randomized timing, and warming new accounts. Architecture matters less than configuration. Treat the "desktop app is safer" claim with healthy skepticism.
Both require one instance per account — Dux-Soup needs a separate Chrome profile per account; Linked Helper needs a separate license per account. For real multi-account workflows (5+ senders from one dashboard), cloud platforms like HeyReach or LinkedNav are dramatically less work.
No, for both tools. Dux-Soup needs Chrome open; Linked Helper needs the desktop app running. For cloud sending where campaigns run 24/7 regardless of your laptop, you need a cloud platform — HeyReach or LinkedNav.
Linked Helper, by a clear margin. The scenario builder is the most configurable in the LinkedIn automation category — conditions, branches, custom fields, and time windows are all exposed. Dux-Soup is simpler and intentionally less configurable.
Free trial only, not a permanent free plan. Dux-Soup is the only one of these two with a genuine free tier (basic profile visits).
Dux-Soup. Chrome extension install is two clicks, the UI is polished, and the configuration surface is intentionally smaller. Linked Helper is powerful but the desktop install plus the configuration depth assume technical comfort.
If neither Dux-Soup nor Linked Helper feels right, try LinkedNav free for 7 days. No credit card. Cancel any time. Most teams know within the first campaign whether the multi-sender plus enrichment plus signals model is the upgrade they were missing.
