LeadMarina vs Instant Data Scraper
Choose Instant Data Scraper if the page in front of you already shows what you need, and a free one-off copy is enough.
Choose LeadMarina if you need the contacts the page doesn't show, read from each business's website and checked before you send or dial.
Instant Data Scraper is a free Chrome extension with a million users on the Chrome Web Store. Open a page, and it guesses where the table of data is, follows the Next button or infinite scroll, and saves what it finds as CSV or Excel. It runs in your browser, and per its store listing the data never leaves it.
That makes it a good way to copy a list you can already see. A lead list needs more than the page shows: a business listing rarely carries an email, so each business's website still has to be read, and the emails and phones still have to be checked. LeadMarina does those steps on every lead before you export it.
Side by side
| Feature | Instant Data Scraper | LeadMarina |
|---|---|---|
| What it is | A free Chrome extension that copies tables and lists from the page in front of you | A lead product: search a niche and a city, get enriched, verified leads |
| Price | Free | $39 / $119 / $299 for 15k / 65k / 240k verified leads, or $699 Unlimited (up to 210,000 leads per 7-day period). Free plan: 100 verified leads, no credit card |
| Emails | Only what the page shows; it does not visit each business's website | Up to 3 emails per lead, from its listing and the business's own website |
| Verification | None: rows are what was on the page | Included on every lead — every email SMTP-checked (safe / risky / invalid / unknown), phones checked for line type + carrier |
| Owner names | Only if the page shows them | Owner names from the business's own website, US public records, or a web search for the business; where none is named, the person the site names as running part of the business, with their role |
| Effort | You drive it: open each page, pick the table, rename the columns, clean the export | One search, with the same named columns every time |
| Delivery | CSV or Excel download | CSV / Excel / JSON, or straight into Google Sheets, Close or GoHighLevel, where re-exports update the leads already sent instead of duplicating them, plus a REST API, a remote MCP server and scheduled searches |

Measured on real leads
What a LeadMarina lead comes with.
97%
of leads come with a phone, almost every one checked for mobile and carrier
About 4 in 10
have a mobile number
About 4 in 10
have an email checked safe to send to
About 1 in 5
come with the owner's name
2.6% had no usable phone or email. When a search returns one of those because we couldn't read the business's website, the lead goes back to your balance automatically.
Measured on a random sample of 52,279 leads delivered in the 30 days to October 29, 2026. How we measured
Finished leads only, with our own test account left out. A pooled figure leans toward the heaviest users, so here is the typical account too: 96% with a phone, 35% with a mobile number, 35% with an email checked safe, and 21% with the owner's name. Checked emails are labeled safe, risky, invalid or unknown, so you can see which ones to send to.

FAQ
Can Instant Data Scraper get emails from Google Maps?+
It copies what a page shows, and a Google Maps listing shows a name, rating, address, and phone number, rarely an email. Getting emails means visiting each business's website, which the extension does not do. LeadMarina reads each website, SMTP-checks the emails it finds and checks phones for line type and carrier.
Is LeadMarina free too?+
There is a free plan: 100 verified leads, every email SMTP-checked and phones checked for line type and carrier, no credit card. Paid plans: $39 / $119 / $299 for 15k / 65k / 240k verified leads, or $699 Unlimited (up to 210,000 leads per 7-day period).
