Overview — What Each Tool Does
Handshake
Handshake is a cloud-based LinkedIn automation platform built for multi-sender rotation. Teams manage unlimited LinkedIn sender accounts from a single dashboard with built-in warmup scheduling, a unified inbox, and premium residential proxies on every plan. Pricing starts at $69/month for 1 sender and scales through Growth ($199/mo for 5 senders) and Scale ($299/mo for 10 senders) tiers — all with unlimited team seats.
Dux-Soup
Dux-Soup is one of the longest-running LinkedIn automation tools, operating since 2016. It started as a Chrome extension and has evolved to include a cloud offering. Dux-Soup has three individual tiers: Pro Dux ($14.99/mo), Turbo Dux ($55/mo), and Cloud Dux ($99/mo). The Pro and Turbo plans operate through a Chrome extension that requires your browser to be open, while Cloud Dux runs independently in the cloud. Dux-Soup also offers team and agency plans, including a Cloud Agency Plan at $371/month for 5+ client seats. It supports LinkedIn, Sales Navigator, and Recruiter with features like drip campaigns, CRM integrations, and funnel flow analytics.

Where Handshake Wins
Handshake's core advantages over Dux-Soup center on multi-sender rotation, unified management, and a consistently cloud-first architecture.
The most fundamental difference is that Dux-Soup's two cheapest plans (Pro Dux and Turbo Dux) are Chrome extensions. Chrome extensions are the highest-risk form of LinkedIn automation — they inject code into LinkedIn's frontend, use your personal IP, and only run when your browser is open. While Dux-Soup offers Cloud Dux at $99/mo to address this, that makes it more expensive than Handshake's $69/mo starter plan while still lacking multi-sender rotation.
Multi-sender rotation is Handshake's defining capability, and Dux-Soup doesn't offer it at any tier. Even the Agency Plan manages accounts from a single dashboard but doesn't automatically distribute leads or rotate outreach between senders. This means each account still operates at its own pace, missing the compounding benefit of coordinated multi-sender campaigns.
Handshake includes premium residential proxies on every plan — a critical safety feature. Dux-Soup's Chrome extension plans expose your personal IP to LinkedIn, and the Cloud Dux plan doesn't clearly specify residential proxy inclusion.
The unified inbox for managing conversations across all sender accounts is another significant operational advantage. When you're running outreach from 5-10 accounts, having every reply in one place eliminates the need to check each account separately.
Where Dux-Soup Wins
Dux-Soup has two meaningful advantages: budget pricing for basic users and mature CRM integrations.
At $14.99/month for Pro Dux, it's one of the cheapest LinkedIn automation tools available. For a solo user who just needs basic connection requests and profile visiting from a single account, the price point is hard to beat. Even Turbo Dux at $55/mo with 12-step drip campaigns undercuts Handshake's $69/mo entry price — though with the Chrome extension limitations.
Dux-Soup's native CRM integrations are more extensive than what most LinkedIn automation tools offer. Direct connections with HubSpot, Pipedrive, Salesforce, and others mean lead data flows into your existing sales stack without relying solely on webhooks or Zapier. For teams with established CRM workflows, this is a genuine advantage.
The Funnel Flow analytics provide a clear visual of how leads progress through campaign stages — a feature that helps teams optimize their outreach sequences. Dux-Soup has also been in the market since 2016, building a large knowledge base, active community, and extensive documentation.
Choose Handshake If...
Choose Handshake if you're running outreach from multiple LinkedIn accounts and need centralized management, multi-sender rotation, and enterprise-grade safety. It's the clear choice for sales teams with 3+ SDRs, agencies managing client accounts, and anyone who wants cloud-based automation with included residential proxies. If you've been using Dux-Soup's Chrome extension and are concerned about account safety, Handshake is a natural upgrade.
Choose Dux-Soup If...
Choose Dux-Soup if you're a solo user on a budget who needs basic LinkedIn automation and is comfortable with Chrome extension limitations. The Pro Dux plan at $14.99/mo is one of the cheapest options in the market. Dux-Soup is also worth considering if you need deep native CRM integrations with HubSpot, Pipedrive, or Salesforce, or if you want to start with a browser-based tool and upgrade to Cloud Dux later.
The Verdict
For solo users on a budget running basic automation from one account, Dux-Soup's lower-tier plans are affordable but come with Chrome extension safety risks. For teams scaling LinkedIn outreach, Handshake is the clear winner: multi-sender rotation, unified inbox, included residential proxies, and better pricing at 5+ senders. Dux-Soup's Cloud Dux plan at $99/mo per account is actually more expensive than Handshake's $69/mo starter while offering fewer features. If safety and scalability are priorities, Handshake delivers more value.
Frequently Asked Questions
Is Dux-Soup a Chrome extension or cloud tool?
Both. Dux-Soup offers Chrome extension plans (Pro Dux at $14.99/mo and Turbo Dux at $55/mo) that require your browser to be open, and a Cloud Dux plan ($99/mo) that runs independently. Handshake is cloud-only from the start.
Are Chrome extension LinkedIn tools safe?
Chrome extensions carry higher risk than cloud-based tools because they inject code into LinkedIn's frontend and use your personal IP address. LinkedIn actively detects and flags extension-based automation. Cloud tools like Handshake operate on separate infrastructure with residential proxies.
Is Handshake cheaper than Dux-Soup Cloud?
Yes. Handshake starts at $69/mo for 1 sender with unlimited team seats. Dux-Soup Cloud Dux costs $99/mo per account with no team features. For 5 senders, Handshake is $199/mo vs. $495/mo for 5× Cloud Dux.
Does Dux-Soup support multi-sender rotation?
No. Dux-Soup manages accounts individually, even on team and agency plans. There's no automatic lead distribution or rotation between sender accounts.
Can I migrate from Dux-Soup to Handshake?
