Datanyze vs StackDetect

Datanyze is a Google Chrome extension for finding B2B contact details and company information while prospecting on sites such as LinkedIn. It provides contact and company data in real time, including email addresses and direct dial phone numbers. Its coverage figures include 63 million direct dials, 84 million email addresses, and 120 million people. Users can tag contacts and companies, create segmented lists, and export them as CSV files. When viewing a company’s employees on LinkedIn, the extension can provide their contact information on the page. Directory pages feature icebreakers drawn from personal social media feeds, local news publications, and other sources. One credit reveals one contact’s information, usable through the extension or directory pages. The product lists technology detection, company profiles, historical technology data, and technology intent signals. Nyze Lite offers 10 credits per month during a 90-day trial. After that trial, access to the platform and previously revealed contact details ends unless the user upgrades. Monthly paid options include Nyze Pro 1 at $29 a month for 80 credits and Nyze Pro 2 at $55 a month for 160 credits.

StackDetect detects and catalogs technologies used by websites, then lets users search, filter, and export prospect lists based on those technologies. It covers CMS platforms, WordPress plugins, ecommerce apps, analytics, advertising pixels, JavaScript frameworks, CDNs, payment gateways, CRMs, and more. Lead lists group websites by the tools they use for outreach, enrichment, or analysis. Each record includes a hostname, detected technologies and categories, confidence, HTTPS status, and last-seen date. Data comes from public pages through a browser extension and proprietary crawler; private or authenticated content is not accessed. The extension collects visited hostnames and detected technologies, not page content, form data, passwords, or personally identifiable information. Detection depends on public fingerprints and varies by technology; less-visited sites may have data weeks old. The free plan costs nothing and includes 50 technology lookups per month and sample lead lists. Paid plans include bulk exports and advanced filters; Business and Enterprise add CRM enrichment and API keys. Each API lookup uses one credit. Included API credits expire after 60 days; purchased top-ups do not.
