Datanyze vs TechStackIntel

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.

TechStackIntel is a technographics API for curated company technology-stack snapshots and taxonomy-backed lookups. Its launch catalog contains 200 curated company domains. GET /v1/lookup handles one domain, while POST /v1/batch/lookup accepts multiple domains through the same lookup pipeline. Responses include company data, cache status, schema version, evidence, and possibly product data. Anonymous access allows 60 requests per hour per IP. Free API keys allow 120 requests per hour, with grace up to 160 before the cap returns. Signup begins with an email magic link; keys can be sent using X-Api-Key or Authorization: Bearer, and GET /v1/usage reports usage. Canonical taxonomy slugs cover company.stack, with schema version 1.1.0 and confidence from 0 to 1. Research submissions accept taxonomy slugs, evidence, and optional products. Coverage is not guaranteed for every domain; missing snapshots return not-found. Curl commands, a thin CLI wrapper, JSON previews, and batch lookup are provided.
