The problem with Wappalyzer (in 2026)
Wappalyzer started life as a free browser extension. Today it's a sales-intel subscription with credit limits, enterprise tiers, and a $149/month floor. For many teams, that's still fine: the brand is mature, the UI is clean, the Salesforce integration works.
But three patterns keep showing up in our own conversations with prospects:
Key facts
- Most-cited pain
- Credits run out mid-sprint
- Second most-cited
- Per-seat pricing for a tool used by one analyst
- Third
- No way to just buy one list and leave
If any of those sound like you, keep reading. Here's how the five serious alternatives stack up.
The five alternatives that actually matter
1. BuiltWith: when coverage is the only thing that matters
BuiltWith indexes 670M+ domains, including every parked page and expired redirect. That's both the strength and the weakness: coverage is unmatched, but so is the noise. Pricing starts at $295/month and ramps fast.

2. W3Techs: for the stat, not the list
W3Techs is the go-to source for "WordPress powers 43% of the web" stats. It's free to browse, authoritative, and updated daily. The catch: you get the percentage, not the underlying list of sites. If you need domains, W3Techs is a dead end.

3. SimilarTech: tech signal with contact enrichment built in
SimilarTech layers email addresses and decision-maker titles on top of tech detection. That's valuable if your outbound motion needs everything in one tool. It's also pricier, contract-locked, and no you can't see pricing without a sales call.

4. HG Insights: enterprise IT spend intelligence
HG's unique angle is estimated IT spend per company, data no one else has. Enterprise ABM teams love it. Pricing reflects that: five figures minimum, annual contracts, mandatory sales cycle.

5. Web Radar: the one-shot alternative
This is us. The pitch is simple:
- Same Wappalyzer ruleset (7,200+ patterns). Same detection accuracy.
- No subscription. Buy a dataset once, own the CSV.
- $29 floor for single-tech lists, up to $499 for deep country + industry cuts.
- Free unlimited domain lookup on the homepage.

A decision shortcut
The real test: ask for the list
Here's the one-question test we use when prospects evaluate us against any competitor:
"I need every Shopify merchant in France with 10+ employees, as a CSV, by end of week."
On that test, W3Techs can't answer (no per-company data). Wappalyzer and SimilarTech can, if you have the right seat tier and burn enough credits. BuiltWith can, if you're on a $500+/month plan. HG will schedule a call.
Web Radar ships the CSV in an hour for $29–$99. That's the moat.
