How we picked
A CRM Chrome extension earns its keep by removing tab-switching from prospecting. We judged these on where the extension works (Gmail only, or LinkedIn and any site?), capture speed (one click to add a contact, or a form to fill?), enrichment (does it auto-pull company and social data?), and engagement actions you can take in-page, like tracking an email or commenting on a prospect's post. Extensions that only mirror the web app without adding a faster capture path didn't make the cut.
What to consider
- LinkedIn-driven outbound → Breakcold. Its extension is built around social selling — capture prospects and engage with their posts without leaving LinkedIn.
- Building a contact database from the web → NetHunt, which adds any profile or page as a structured record straight into Gmail.
- You want enrichment, not data entry → Salesflare, whose extension auto-fills contacts and companies from LinkedIn and the open web.
- Heavy Google Workspace user → Copper, the smoothest browser experience for teams who live in Gmail, Calendar, and Drive.
- Free and broad ecosystem → HubSpot, whose extension pairs with the largest app marketplace in the category.
Pricing snapshot
Most options cluster around $29–$30/user/mo: Breakcold from $29/mo, Salesflare from $29/user/mo, and NetHunt from $30/user/mo. Copper advertises a $9/user/mo Starter but most teams need a higher tier (~$59/user/mo) for full functionality. HubSpot is the outlier with a genuinely free CRM and extension, making it the lowest-risk way to try the browser-capture workflow.
How the extensions handle LinkedIn
LinkedIn is where this category separates. Breakcold treats it as a primary surface: you can add a prospect, read their recent posts, and engage with their content to warm them before outreach — the extension is essentially a social-selling cockpit. Salesflare uses LinkedIn differently, scraping profile and company details to keep your CRM records complete with zero typing. NetHunt lets you clip any profile into a structured Gmail-based record. Copper and HubSpot, by contrast, are inbox-first and treat LinkedIn as secondary. If your pipeline starts on LinkedIn, weight Breakcold and Salesflare heavily; if it starts in your inbox, the Gmail-native extensions will feel more at home.
