Top Affordable Website Technology Detection Tools: Wappalyzer and BuiltWith Alternatives
Looking for a technology detection tool that won’t blow your budget? You’re not alone. While Wappalyzer and BuiltWith dominate the market, their pricing—often $250 to $500+ per month—puts them out of reach for many teams.
The good news: capable alternatives exist at a fraction of the cost. In this guide, I’ll compare the major options honestly, including where each excels and falls short.
What Technology Detection Tools Actually Do
Before comparing options, let’s be clear about what these tools provide:
- Website technology identification: Detect what CMS, frameworks, analytics, and other tools a website uses
- Bulk lookups: Search across millions of websites to find companies using specific technologies
- Lead generation: Turn technology data into prospect lists for sales outreach
- Competitive research: Understand what technologies competitors and target markets use
Different tools emphasize different capabilities. Your choice depends on which features matter most for your use case.
The Premium Players: Wappalyzer and BuiltWith
Wappalyzer
Wappalyzer has become the industry standard for technology detection. Their database covers 3,000+ technologies with strong accuracy.
What they do well:
- Excellent browser extension (the free version is genuinely useful)
- Most comprehensive technology database
- Daily data updates for accuracy
- Strong API for developers
The catch: Pro plans start at $250/month. Business is $450/month. For teams doing occasional research, that’s hard to justify.
Best for: Security teams, enterprises needing compliance-grade data, developers building integrations.
BuiltWith
BuiltWith combines technology detection with lead generation features, making it popular with sales teams.
What they do well:
- Strong B2B lead generation capabilities
- Historical technology tracking (see when companies adopted or dropped tools)
- Good coverage of e-commerce and marketing technologies
The catch: Basic plan is $295/month with limited features. Pro is $495/month. Team plans hit $995/month.
Best for: Enterprise sales teams with dedicated budgets for lead generation data.

Choose WhatRuns if:

The Bottom Line
Wappalyzer and BuiltWith earned their market positions with solid products. But their pricing assumes enterprise budgets that many teams don’t have.
For most B2B teams focused on lead generation, affordable alternatives like TechLeads.fyi deliver comparable functionality at 70-80% lower cost. The tradeoff is usually brand recognition and some advanced features rather than core capabilities.
