Ranked by category
Extraction
- Leadsforlinked: 8 sourcing methods, no Sales Nav requirement, 100 free leads. The clearest modern pick for anyone starting from scratch.
- Evaboot: clean CSV export, but needs Sales Navigator ($99+/mo) running underneath to work at all.
- Wiza: enrichment-focused, gets expensive fast once volume climbs past a small list.
Enrichment (email/phone)
- Kaspr: phone numbers, generally EU-friendly on data sourcing. Limited free tier.
- Lusha: large underlying database, occasional GDPR-sourcing concerns raised publicly by users.
- Hunter: domain-based email finder, useful but not LinkedIn-native.
Outreach automation
- Dux-Soup: dated interface, low price, built for solo use rather than teams.
- Waalaxy: more polished interface, higher price to match.
- Skylead: conditional Smart Sequences are the standout feature, mid-tier pricing.
CRM sync & productivity
- HubSpot Sales: official integration, syncs LinkedIn activity straight into HubSpot's CRM.
- Surfe: one-click export to multiple CRMs (HubSpot, Pipedrive, Salesforce).
- Crystal: personality-insight overlay on profiles. Niche, but genuinely useful for tailoring tone.
What to install vs avoid
- Install (max 3 at once): one extraction tool, plus one enrichment or outreach tool, plus optionally one CRM sync tool.
- Avoid: running two outreach automation tools simultaneously. Independent, overlapping actions on the same account read as more automated to LinkedIn's detection than either tool alone.
- Avoid: unfamiliar free extensions with very few installs and no visible update history. Low-adoption LinkedIn extensions are a real vector for cookie-stealing malware, since a compromised session cookie hands over full account access.
Safety checklist before installing any extension
- Check the Chrome Web Store rating and review volume; treat a handful of reviews with more caution than hundreds, regardless of the star average.
- Check the developer's website is real, not a typosquatted domain that mimics a known brand.
- Read the permissions list carefully. "Read and change all your data on all websites" is disproportionate for a tool that only needs to work on linkedin.com.
- Check the Chrome Web Store's last-updated date. LinkedIn's interface and anti-automation signals change often enough that a tool untouched for 6+ months is worth a second look before trusting it with your account.
Frequently asked questions
How many LinkedIn prospecting extensions should I run at once?
No more than 2 or 3: typically one extraction tool, one outreach or enrichment tool, and optionally one CRM sync. Stacking 5 or more slows LinkedIn's page loading noticeably and increases the chance of two extensions triggering conflicting or duplicate actions on the same page.
What permissions should make me suspicious of a prospecting extension?
"Read and change all your data on all websites" is disproportionate for a tool that only needs to work on linkedin.com. A well-scoped extension requests access to the specific site it operates on, not your entire browsing history and every other site you visit.
Can two outreach automation extensions safely run at the same time?
No, this is one of the more common self-inflicted account risks. Two tools independently sending connection requests or messages on the same account can create conflicting, overlapping actions in a short window, a pattern that looks far more automated to LinkedIn's own detection than either tool running alone.
How do I check if an extension is still actively maintained?
The Chrome Web Store listing shows a last-updated date; anything older than 6 months for a LinkedIn-facing tool is a signal to look closer, since LinkedIn's interface and bot-detection both change often enough that an unmaintained extension tends to break or fall behind quietly.
