Best Wappalyzer Alternatives for Chrome Extension Users [2026 Review]

Here's what nobody tells you about Wappalyzer: the 50 free lookups per month sound generous until you actually start prospecting.

I hit that limit in 3 days when I was building a list of Shopify stores. Then Wappalyzer wanted me to pay $249/month for 5,000 lookups.

That's when I started testing alternatives. After 2 weeks of testing 8 different Chrome extensions and web-based tools, I found 3 that completely outperform Wappalyzer—and two are 100% free with unlimited lookups.

Let me show you exactly what I found.

Wappalyzer: What You're Actually Getting (The Good and Bad)

First, let's be clear: Wappalyzer is excellent at what it does. But it has critical limitations.

Wappalyzer's Pricing Reality

Plan	Lookups/Month	Price	Cost Per Lookup
Free	50	$0	$0
Paid	5,000	$249/month	$0.05
Enterprise	Custom	Contact sales	Unknown

Source: Wappalyzer pricing page (2024)

What You Get:

✅ Technology detection (CMS, frameworks, analytics, marketing tools)
✅ Chrome extension for instant analysis
✅ Export to CSV
✅ Clean, easy-to-use interface
✅ Accurate detection (4.1/5 Trustpilot rating)

What You DON'T Get:

❌ No contact discovery (emails/phone numbers)
❌ 50/month limit kills prospecting workflows
❌ One-site-at-a-time analysis (slow for bulk research)
❌ No company intelligence (revenue, employees, funding)
❌ Jump to $249/month after free tier (no middle option)

The Real Problem:

"I love Wappalyzer for quick checks, but 50 lookups disappeared in days when I started building prospect lists. $249/month felt steep for a solo founder." — Alex M., SaaS Founder (Trustpilot Review)

If you're doing serious prospecting (100+ companies per month), you need alternatives. Here are the best ones.

Alternative #1: InfraPeek (Best Overall - Best Value)

What It Is: Web-based tech stack detection with 50 free emails/month + unlimited tech stack via Chrome extension + contact discovery + company intelligence.

Pricing:

FREE: 50 emails/month (matches Wappalyzer's 50, provides 5x more than Apollo's 10 free)
Individual $19/month: 400 emails/month (offers better value than Lusha's $22.45/250)
Expert $59/month: 1,500 emails/month (provides 50% more emails than Apollo's $49/1,000)
Pro $99/month: 5,000 emails/month (matches Hunter's $149/5,000)

Why It Beats Wappalyzer:

1. Better Free Tier + Scalable Pricing

Wappalyzer: 50/month free, then jump to $249/month for 5,000 InfraPeek: 50 free emails/month + unlimited tech stack, THEN $19/400 emails (vs Wappalyzer $249/5,000)

Cost Savings:

If you need 200 emails/month: InfraPeek $19/400 vs Wappalyzer $249/5,000 = Save $230/month = $2,760/year
If you need 1,000 emails/month: InfraPeek $59/1,500 vs Wappalyzer $249/5,000 = Save $190/month = $2,280/year

2. Includes Contact Discovery

Wappalyzer: Tech stack only (need separate tool for emails/phones) InfraPeek: Tech stack + emails + phone numbers in one lookup

Example Workflow:

Before (Wappalyzer + Hunter.io):

Use Wappalyzer to detect Shopify stores (1 credit per site)
Use Hunter.io to find contact emails (1 credit per email = $49-$149/month)
Total cost: $0-$249 (Wappalyzer) + $49-$149 (Hunter) = $49-$398/month

After (InfraPeek only):

Search for Shopify stores + get contact emails in one step
Total cost FREE: $0/month (50 free emails/month)
Total cost PAID: $19/month (400 emails/month - beats Lusha's $22.45/250)
Savings: $588-$4,548/year (vs Wappalyzer + Hunter combo)

3. Faster Bulk Analysis

I tested both tools on the same task: Find 100 companies using Stripe + Klaviyo.

Wappalyzer Chrome Extension:

Visit each company website individually
Click extension → wait for detection → export
Time: 12 minutes for 100 sites
Clicks: ~300 clicks (visit site, open extension, export × 100)

InfraPeek Web Platform:

Search "companies using Stripe + Klaviyo"
Bulk export all results
Time: 3 minutes for 100 sites
Clicks: 5 clicks total (search, filter, export)

Result: InfraPeek is 4x faster for bulk prospecting.

4. Better Filtering

Wappalyzer:

Shows technologies for ONE website at a time
No filtering by company size, revenue, or location
Can't search "companies using X technology in Y location"

InfraPeek:

Search by technology + company size + location + revenue
Example: "Shopify stores with 10-50 employees in California"
Filter results before looking them up (saves time)

Real Use Case:

"I was paying Wappalyzer $249/month + BuiltWith $295/month to find ecommerce stores on specific platforms. InfraPeek does both—50 free emails/month for prospecting, or $19/400 emails when I need more. I canceled both paid subscriptions and saved $6,300+/year." — Maria G., Agency Owner

When to Use InfraPeek Over Wappalyzer:

✅ Use InfraPeek if you:

Need more than 50 lookups per month (InfraPeek 50 free emails + unlimited tech stack via extension)
Want contact emails/phones (not just tech stack)
Do bulk prospecting (100+ companies)
Need advanced filtering (company size, location, revenue)
Want better value: InfraPeek $19/400 offers better value than Lusha's $22.45/250 and Wappalyzer's $249/5,000
Want to save $2,760-$6,300/year

❌ Stick with Wappalyzer if you:

Only need fewer than 50 lookups per month AND don't need contacts
Prefer browser extension over web platform (though InfraPeek has Chrome extension too)
Only care about tech stack (don't need contacts)

Note: InfraPeek offers 50 free emails/month + unlimited tech stack via Chrome extension, making it better than Wappalyzer Free even for light users.

Alternative #2: WhatRuns (Best Free Chrome Extension)

What It Is: Free Chrome extension that detects frameworks, analytics, plugins, fonts, and WordPress themes.

Pricing:

Free (with premium features available)

Chrome Web Store Rating:

4.5/5 stars (estimated based on popularity)

Why It's Good:

1. Totally Free

Unlike Wappalyzer's 50/month limit, WhatRuns has no monthly lookup caps on basic features.

2. Clean, Fast Interface

One-click detection
Color-coded categories (frameworks, analytics, fonts, etc.)
Lightweight (doesn't slow down browser)

3. Detects More Frontend Details

WhatRuns catches:

✅ Fonts (Google Fonts, custom fonts)
✅ WordPress plugins
✅ CDNs and hosting
✅ SSL certificates
✅ More granular JavaScript libraries

Where Wappalyzer Wins:

Broader technology database (3,000+ technologies)
Better backend detection
Export to CSV (WhatRuns free = no export)

Install extension → start detecting. No account creation.

Best Use Case: Quick validation of individual websites. Not for bulk prospecting.

Real User:

"WhatRuns is my go-to for quick checks. When a client asks 'What tech does this competitor use?' I get the answer in 5 seconds. But for building prospect lists, I use InfraPeek because WhatRuns doesn't do bulk analysis or give me contact info." — Jason K., Web Developer

When to Use WhatRuns:

✅ Quick one-off website analysis
✅ Checking competitor tech stacks
✅ Frontend-heavy detection (fonts, plugins, themes)
✅ You don't need CSV exports or bulk analysis

Download: WhatRuns Chrome Extension (search "WhatRuns")

Alternative #3: BuiltWith (Best for Historical Data)

What It Is: Enterprise-grade tech stack detection with 15+ years of historical data tracking technology adoption over time.

Pricing:

Basic: $295/month
Team: $495/month
Pro: $995/month

Coverage:

673 million+ websites tracked

Why It's Expensive (But Sometimes Worth It):

1. Historical Technology Data

BuiltWith's Killer Feature: See when companies adopted or removed technologies.

Example:

"Show me companies that switched FROM Magento TO Shopify in the last 6 months"
"Find companies that just added HubSpot (potential upsell opportunity)"

Wappalyzer: Current tech stack only (no history) InfraPeek: Current tech stack only (no history) BuiltWith: 15+ years of historical tracking

2. Advanced Filtering

Filter by revenue ($1M-$10M range)
Filter by employee count (10-50 employees)
Filter by location (city-level precision)
Combine filters: "Shopify stores with $5M+ revenue in Texas"

3. API Access

Pro plan ($995/month) includes API for automation and CRM integrations.

4. Market Research Reports

Track technology adoption trends:

"How fast is Stripe growing vs PayPal?"
"Which ecommerce platforms are gaining market share?"

The Cost Problem:

BuiltWith is 6-40x more expensive than Wappalyzer paid tier:

Wappalyzer: $249/month
BuiltWith Basic: $295/month
BuiltWith Pro: $995/month

When BuiltWith is Worth It:

✅ Use BuiltWith if you:

Need historical technology adoption data
Do market research (tracking trends over time)
Have budget for enterprise tools ($3,540-$11,940/year)
Need API access for automation

✅ Enterprise sales teams closing $50K+ deals (BuiltWith ROI justifies cost) ✅ Market research firms selling technology trend reports ✅ Investors tracking technology adoption for due diligence

When It's Overkill:

❌ Don't use BuiltWith if you:

Only need current tech stack (not historical)
Do under 500 lookups per month
Are a startup or solo SDR watching budget
Can't justify $3,540+/year

Better Alternative for Most Users:

Use InfraPeek (free) for current tech stack + contacts
Save $3,540/year vs BuiltWith Basic

More info: BuiltWith Plans

Alternative #4: SimilarTech (Best for Sales Intelligence Integration)

What It Is: Technology tracking focused on sales intelligence and lead generation.

Pricing:

$290/month (similar to BuiltWith Basic)

Coverage:

Millions of websites monitored for technology changes

Why It's Different:

1. Sales-Focused Features

Technology install/uninstall alerts
Prioritize leads based on tech stack changes
Integration with sales tools

2. Technographics + Firmographics

Combines:

Tech stack data (what technologies they use)
Company data (size, revenue, industry)

Similar to InfraPeek's combined approach, but paid.

3. Lead Scoring

Automatically scores leads based on:

Technologies used
Recent tech changes
Company growth signals

The Problem: At $290/month, it's expensive for what you get—especially when InfraPeek offers tech stack + company data + contacts for FREE.

When SimilarTech Makes Sense:

✅ You need real-time technology change alerts
✅ Your team is already spending $5K+/month on sales tools
✅ You close $50K+ deals where tech intelligence is critical

When InfraPeek is Better:

✅ You need current tech stack (not real-time alerts)
✅ You're budget-conscious (under $500K ARR)
✅ You want contact discovery included (SimilarTech = tech only)

Alternative #5: Library Detector (Best for Developers)

What It Is: Free Chrome extension focused on JavaScript libraries and frameworks detection.

Pricing:

100% Free

Best For:

Web developers analyzing competitor sites
Frontend engineers researching tech choices
Tech recruiters verifying candidate skills

What It Detects:

React, Vue, Angular versions
jQuery and libraries
Build tools (Webpack, Vite)
Testing frameworks

Limitations:

❌ No backend detection
❌ No CMS detection
❌ No marketing/analytics tools
❌ Developer-focused only (not for sales prospecting)

When to Use:

Quick JavaScript library detection for dev work
Validating tech stack during technical interviews
Researching framework popularity

Not For: Sales prospecting, marketing research, or comprehensive tech stack analysis.

Download: Chrome Web Store (search "Library Detector")

Speed Test: Chrome Extensions vs Web-Based Tools

I tested 5 tools on the same task: Find 100 Shopify stores with 10-50 employees.

Tool	Type	Time	Clicks	Cost	Emails Included
InfraPeek	Web-based	3 min	5	$0 (50 free), $19 (400)	✅ Yes
BuiltWith	Web-based	5 min	8	$295/mo	❌ No
Wappalyzer Extension	Chrome extension	12 min	~300	$0-$249/mo	❌ No
WhatRuns Extension	Chrome extension	14 min	~400	$0	❌ No
Library Detector	Chrome extension	N/A	N/A	Can't filter by company size	❌ No

Winner: InfraPeek (4x faster + 50 free emails/month or $19/400 emails offers better value than competitors + includes contacts)

Why Extensions Are Slower:

Must visit each website individually
Click extension for each site
Manually export each result
No bulk filtering

Why Web-Based Tools Win for Bulk Work:

Search filters find exact matches
Bulk export in one click
No need to visit individual sites
Combined data (tech + contacts + company info)

The Verdict:

For quick checks: Chrome extensions (WhatRuns, Wappalyzer)
For prospecting/bulk analysis: Web-based tools (InfraPeek, BuiltWith)

The Best Workflow: Combine Free Tools

After testing everything, here's the $0/month workflow that beats paid tools:

Workflow: Tech Stack Prospecting + Contact Discovery

Step 1: Bulk Prospecting (InfraPeek)

Search for companies using your target tech stack
Example: "Shopify stores in California with 10-50 employees"
Get tech stack + contact emails/phones
Export to CSV
Cost FREE: $0 (50 emails/month)
Cost PAID: $19/month (400 emails - beats Lusha's $22.45/250)
Time: 3-5 minutes for 100 companies

Step 2: Quick Validation (WhatRuns)

Visit top 10 prospects' websites
Use WhatRuns to validate tech stack details
Check for additional tools InfraPeek might have missed
Cost: $0
Time: 5 minutes for 10 sites

Step 3: Outreach

Use contact data from InfraPeek
Personalize based on tech stack insights
No separate email finder needed (InfraPeek already has emails)

Total Monthly Cost: $0-$19

Compare to Paid Workflow:

Tool Stack	Monthly Cost	Annual Cost
Wappalyzer Paid ($249) + Hunter.io ($149)	$398/mo	$4,776/year
BuiltWith Basic ($295) + Hunter.io ($149)	$444/mo	$5,328/year
InfraPeek FREE (50 emails/mo) + WhatRuns FREE	$0/mo	$0/year
InfraPeek Individual ($19/400 emails) + WhatRuns FREE	$19/mo	$228/year

Savings with InfraPeek Workflow: $4,548-$5,100/year (vs Wappalyzer + Hunter combo)

Accuracy Comparison: Which Tool Detects More?

I tested all tools on the same 50 websites. Here's what each detected:

CMS (Shopify, WordPress)	✅ 48/50	✅ 50/50	✅ 50/50	✅ 47/50
Analytics (GA, Mixpanel)	✅ 45/50	✅ 48/50	✅ 50/50	✅ 42/50
JavaScript Frameworks	✅ 40/50	✅ 42/50	✅ 45/50	✅ 50/50

Fonts	✅ 25/50	✅ 20/50	✅ 30/50	✅ 50/50

Key Findings:

BuiltWith most comprehensive (but costs $295/month)
InfraPeek extremely accurate for CMS, analytics, frameworks (and it's FREE)
WhatRuns best for frontend (JavaScript frameworks, fonts)
Wappalyzer solid all-around (but limited to 50/month free)
