Bulk tech stack lookups without a $250 subscription
You want to know what a list of websites is built with, inside a spreadsheet, a CRM, n8n or an AI agent: CMS, ecommerce platform, analytics, CDN, email provider. Here is where Wappalyzer's plans stand, and what PlainRows offers.

What PlainRows charges
No subscription to us. The tool runs on Apify: the free Apify plan is enough to test it, and the Starter plan ($19 per month, with $19 of usage included, apify.com/pricing) removes the free-plan limits.
| Data | Tool | Price (Starter plan) |
|---|---|---|
| Technologies found on the homepage of each website, matched against 7,600+ open-source fingerprints, with versions when shown: one column per category (CMS, ecommerce, analytics, tag managers, advertising, CRM, email, live chat, payments, CDN, hosting, frameworks...), plus title, meta description, language, server headers, and the e-mails, phone links and social profiles shown on the homepage. About 150 websites per minute in our tests. | Tech Stack Detector API | $0.0009 per website analysed; sites that are down, blocked or do not exist are free |
Example: 5,000 websites, the lookups included in Wappalyzer Pro, cost about $4.50.
When Wappalyzer is the better choice
- You need technologies that only appear after JavaScript runs or on pages other than the homepage. PlainRows loads the homepage over HTTP, without a browser, so it can miss them.
- You want ready-made lead lists of all sites using a technology, company details and email verification in the same tool.
- You only check a few sites a month: the free plan's 50 lookups may be enough.
When PlainRows is the better choice
- You already have a list of domains and want their stack in bulk, at a price per website rather than per month.
- You want one spreadsheet-ready row per site, with one column per category, to filter on
ecommerce = Shopifyin one click. - You also want the e-mails, phone links and social profiles shown on each homepage, in the same row, at no extra cost.
- You run it from n8n, Make, Zapier, Google Sheets or an AI agent (MCP), with a hard cap: every run stops at the maximum cost you set.
