BuiltWith vs Datanyze: They Solve Different Problems
Your VP of Sales wants a list of every company running Shopify Plus - with decision-maker emails - by Friday. You open BuiltWith and get the company list in minutes. Then you realize it doesn't give you a single email address. So you open Datanyze, find some contacts, and half the emails bounce.
The technographic data market grew from $367M in 2020 to over $1.1B, but most teams weighing BuiltWith vs Datanyze still can't get both pieces from one tool: what technology a company uses and how to actually reach someone there.
Here's the thing - these two tools aren't really competitors. Every comparison page that lines them up feature-for-feature is misleading you.
30-Second Verdict
- Pick BuiltWith if you need to know what technology a company runs - market intelligence, competitor displacement, tech-stack prospecting. Starts at $295/mo.
- Pick Datanyze if you need cheap contact reveals on a tight budget and can tolerate data accuracy issues. Starts at $29/mo.

What Each Tool Actually Does
BuiltWith is a telescope. Datanyze is a fishing rod. One shows you what companies use. The other tries to tell you who works there.
BuiltWith - Technology Detection at Scale
BuiltWith tracks 113,007 technologies across 414 million domains, with weekly updates and 18+ years of technology trend data. You type in a domain and see every piece of technology it runs - analytics, CMS, payment processors, CDNs, the works.
The real value is list building: filter by technology, geography, and traffic tier to build prospect lists of companies using a specific tool. It also maintains an ecommerce store directory with vertical categorization, which is useful for agencies targeting specific niches. Competitive displacement campaigns live and die on this data. We've used it to map entire market segments by tech stack, and nothing else comes close for that particular job.

Datanyze - Contact Data with a Thin Tech Layer
Datanyze claims 48M direct dials, 84M emails, and 120M contacts. It started as a technographic tool, but after ZoomInfo acquired it in September 2018, the product shifted toward budget contact reveals via a Chrome extension. The technographic layer still exists, but it's shallow compared to BuiltWith's depth. ZoomInfo positions Datanyze as a lighter-weight, budget-friendly product alongside its flagship platform - and the feature set reflects that.
Pricing Compared
The pricing gap tells you everything about positioning. BuiltWith charges for intelligence. Datanyze charges for contacts.
| Plan | Monthly | Annual | Key Limits |
|---|---|---|---|
| BuiltWith Advanced | - | $144/yr | Detailed lookups only, no lists |
| BuiltWith Basic | $295/mo | $2,950/yr | 2 technologies, 2K uploads |
| BuiltWith Pro | $495/mo | $4,950/yr | Unlimited tech, 20K uploads |
| BuiltWith Team | $995/mo | $9,950/yr | Unlimited + 100K API credits/mo |
| Datanyze Lite | Free | Free | 10 credits/mo |
| Datanyze Pro 1 | $29/mo | ~$21/mo billed annually | ~80 credits/mo |
| Datanyze Pro 2 | $55/mo | ~$39/mo billed annually | ~160 credits/mo |
BuiltWith's Basic plan limiting you to just 2 technologies at $295/mo is borderline insulting. If you're prospecting into companies using Shopify AND Klaviyo, you've already maxed out your Basic plan - you need Pro at $495/mo for anything serious. The $144/year Advanced plan is decent for individual lookups, but it won't build lists.
Datanyze is cheap. That's the whole pitch. But something that should be on their pricing page: revealed contacts can become locked after cancellation unless you resubscribe.

BuiltWith can't give you emails. Datanyze emails bounce. Prospeo combines technographic filters with 98% verified email accuracy - so you go from "companies running Shopify Plus" to decision-maker inboxes without switching tools or burning your domain.
Stop paying for two half-tools. Get tech-stack targeting and verified contacts at $0.01/email.
Data Quality: Where the Gap Widens
BuiltWith earns a 4.4/5 on G2, and the technology detection is reliable. We've found it accurate for major platforms and reasonably good for niche tools, though the CSV exports need at least one round of deduplication and cleanup before they're usable - especially at scale. You're getting company-level data, not contact-level, so you still need another tool to find people.
If you're trying to protect deliverability while prospecting, pair this with an email deliverability guide and a workflow for how to check if an email will bounce.

Datanyze is a different story. G2 reviewers consistently flag data accuracy issues (4.1/5 across 446 reviews), and one Capterra reviewer called the data "90% inaccurate." That's an outlier, but the pattern is clear: cheap data you can't trust costs more than expensive data that works, because bounced emails burn your domain reputation. Capterra rates it 3.7/5, with billing friction and nonexistent customer support as recurring complaints.
Let's be honest - if your average deal size sits below five figures, you probably don't need BuiltWith-level technographic depth. But you absolutely need accurate contact data. Most teams comparing these two tools are solving the wrong problem. They need one platform that does both adequately, not two that each do half the job.
Who Should Pick Which
Market researcher or competitive analyst - BuiltWith, no question. The historical trends and technology coverage are unmatched. Wappalyzer is a free browser extension for basic individual lookups, but it can't build lists.
If you're building outbound around these insights, it helps to align with account-based selling best practices.

Budget SDR who needs quick contact reveals - Datanyze works if you verify independently. At $29/mo for around 80 reveals, it's one of the cheapest options out there. But run every email through a verification tool before you sequence it. The consensus on r/b2b_sales is that it's "very inexpensive" - and the price reflects the quality. Lusha is worth considering if accuracy matters more than cost.

Agency building tech-stack prospect lists - BuiltWith for the lists, then a separate contact tool to find people. We've tested both workflows, and the two-tool approach adds 15-20 minutes per list compared to a single platform. Practitioners on r/techsales describe the same friction, pairing BuiltWith with Apollo or similar for Shopify/DTC prospecting.

FAQ
Is Datanyze still being developed after the ZoomInfo acquisition?
Datanyze still operates as a standalone product after the 2018 ZoomInfo acquisition, positioned as a budget-friendly contact reveal tool. Feature updates have been minimal - ZoomInfo funnels most R&D into its flagship platform, so don't expect major new capabilities anytime soon.
Can I use BuiltWith for free?
Individual site lookups are free forever on BuiltWith's site. List building, filtering, and exports require a paid plan starting at $295/month. The $144/year Advanced plan covers detailed individual domain lookups but won't generate prospect lists.
What's a good alternative if I need technographics and verified emails together?
Prospeo includes technographic filters alongside 300M+ professional profiles with 98% email accuracy and 125M+ verified mobiles. Filter by technology stack and get verified emails and direct dials in one search - no need to pair two separate tools. The free tier includes 75 emails per month, so you can test it without risk.
