Cloud vs browser-extension LinkedIn outreach tools: where does the work run?

Ask three questions about each shortlisted tool. Where does the operator build a list and review copy? Where does the next LinkedIn action actually run? Where are the session, queue, replies, and exclusion decisions stored? An extension may be part of setup while the action engine runs elsewhere. A web dashboard alone does not answer any of the latter questions.

Dux-Soup's own guide distinguishes a browser mode that uses the operator's computer from a cloud mode that runs queued actions on its servers. It also says Chrome is required for the cloud mode's initial installation. Waalaxy's published comparison calls Waalaxy a Chrome extension and Expandi cloud-based; Expandi calls its own platform cloud-based. These are vendor descriptions, not an independent audit of either product's execution path. Request an architecture answer for the specific plan and action you would use.

For Dux-Soup's documented browser mode, the local computer must be on for activity to run. Its cloud mode can continue after that computer is off. That behavior is product-specific. A plan can split capture, campaign setup, and execution across the two places.

Ask the vendor to show, without sending to live prospects, what happens when a laptop sleeps, an extension disconnects, or a remote session expires. Does the queue pause, retry, or continue? What does the operator see before anything resumes? A local process may fit a team that wants activity tied to an attended machine. A remote process may fit a team that needs continuity, provided its stop controls and session custody are acceptable. Neither preference answers the platform-policy question.

The operator needs to know whether a pause reaches actions already queued. Ask who can inspect and cancel those actions for each sender, whether a reply or exclusion stops the right follow-up, and whether the audit trail survives export and offboarding. Make the vendor demonstrate these states in a non-sending walkthrough; do not infer them from a cloud or extension badge.

Keep an internal owner for account access and recipient decisions. If the team cannot explain where the session is held, who can disconnect it, or how it will reconcile replies across tools, leave the account and prospect out of an automated campaign. The related migration checklist covers carrying that history into a replacement system.

LinkedIn says it does not permit third-party software, including browser plug-ins and extensions, that scrape, change the appearance of, or automate activity on its website. It warns that accounts using prohibited tools can be restricted. The published policy states no cloud-hosting exception. Vendor claims about dedicated IPs, human-like timing, or being undetectable do not establish permission or a measured safety advantage.

Start with the activity the team actually needs. Research, reminders, and human-run native messaging may satisfy it without an automated action engine. If a proposed workflow depends on third-party automation, the account owner needs the policy decision before comparing uptime or seats. No cross-vendor execution or account-safety trial supports a winner here; a vendor that cannot demonstrate queue and session control is not ready for the shortlist.
