Kaspr vs Lusha: Browser Extension Showdown for Lead Gen

You've found the perfect prospect on LinkedIn. They match your ICP down to the last detail — right industry, right title, right company size. Then you hit the wall: no contact info. You can send a connection request and hope for the best, or you can use a browser extension to pull their email and phone number in seconds. The question is which one you trust with that job. Kaspr and Lusha are two of the most popular options in this space, and on the surface they look almost identical. Both sit in your browser, both surface contact data from LinkedIn profiles, and both promise to make your prospecting faster. But after spending real time with both tools — and comparing them against alternatives like Apollo, ZoomInfo, and Snov.io — the differences become pretty clear. Let's get into it.

What Each Tool Actually Does (And Who It's Built For)

Kaspr is a browser extension built almost exclusively around LinkedIn prospecting. It was acquired by Cognism in 2022, which tells you something about the direction it's headed. When you land on a LinkedIn profile or a Sales Navigator search result, Kaspr overlays a widget that lets you reveal phone numbers and email addresses with a single click. It also has a built-in workspace where you can organize leads into lists, add notes, and push contacts directly into your CRM. The interface feels clean and modern — clearly designed with SDRs in mind who are spending four hours a day on LinkedIn.

Lusha, on the other hand, has grown into something a bit bigger. It started as a simple contact enrichment plugin but now offers a full prospecting platform with its own database, bulk enrichment capabilities, and team analytics. The extension still works similarly to Kaspr — hover over a LinkedIn profile, get the contact data — but Lusha positions itself more as an all-in-one data solution rather than just a LinkedIn tool. This matters depending on whether you want a focused instrument or a broader platform.

In terms of target audience: Kaspr tends to be the pick for individual SDRs and small sales teams doing heavy LinkedIn outreach. Lusha appeals to slightly larger teams and RevOps folks who need enrichment across multiple channels, not just LinkedIn.

Data Quality and Coverage: Where It Gets Real

This is where tools like this live or die. Having a button that reveals contact info is useless if half the emails bounce or the phone numbers go to someone who left the company two years ago.

Kaspr leans heavily on its connection to Cognism's data infrastructure, which has strong European coverage in particular. If you're prospecting into GDPR-heavy markets like the UK, Germany, or France, Kaspr has a genuine edge because Cognism has invested significantly in compliant, verified data for those regions. For North American data, it's solid but not exceptional — you might find it slightly thinner than what Apollo or ZoomInfo can pull up for mid-market US companies.

Lusha's database claims over 100 million business profiles, with strong US coverage and decent global reach. In practice, Lusha tends to return more mobile phone numbers for US-based contacts, which is valuable if you're doing cold calling alongside email outreach. The accuracy on direct dials has been one of Lusha's consistent selling points in user reviews across the board.

Neither tool will give you 100% accuracy — that's not how B2B contact data works. But if your team is primarily prospecting in North America and needs mobile numbers, Lusha has a slight edge. If you're doing a lot of European prospecting, Kaspr's Cognism backing gives it the advantage.

Pricing: What You're Actually Paying

Both tools offer free tiers, which is how most people get hooked. Here's how the pricing actually breaks down:

Kaspr offers a free plan with 5 phone credits and 5 email credits per month — enough to kick the tires but not enough for real prospecting. Paid plans start around $49/month per user for the Starter tier, which gives you more credits and CRM integrations. The Growth plan runs around $79/month and unlocks team features and higher credit limits. Enterprise pricing is custom.

Lusha also has a free tier giving you 5 credits per month. Their Pro plan starts at $36/month (billed annually) for individual users, which is actually cheaper than Kaspr at the entry level. The Premium plan for teams runs around $59/month per user, and Scale is custom. Lusha's team plans include analytics dashboards and admin controls that Kaspr doesn't match at equivalent price points.

Worth noting: both tools use credit-based systems, and you'll burn through credits faster than you expect if you're doing serious volume. If you're doing high-volume prospecting, also look at what Apollo offers on their paid tiers — the credit allocations are often more generous for the price.

Integrations: Getting the Data Where You Need It

Both extensions support direct integration with major CRMs, but the depth varies. Here's a quick comparison:

One important note: neither Kaspr nor Lusha does outreach natively. Once you've got the contact data, you'll need to push it into a sequencing tool like Saleshandy, Lemlist, or a CRM like HubSpot to actually run your campaigns. If you want the whole workflow in one place, Apollo is worth a serious look — it combines prospecting data with email sequencing, which cuts down on tool switching considerably.

User Experience and Support: The Day-to-Day Reality

Kaspr's extension is noticeably snappier when you're working through LinkedIn profiles quickly. The workflow of revealing a contact, adding them to a list, and pushing to CRM feels well thought out for the SDR use case. The internal workspace also makes it easy to manage leads without leaving the tool entirely.
