Best Wappalyzer alternatives in 2026: 10 tools compared

Wappalyzer is showing its age. Long-term users report accuracy issues, the free tier caps at 50 lookups per month, and the cheapest paid plan is $250/month. That's a hard sell when there are better options at a fraction of the price.

We tested 10 tools that do what Wappalyzer does, some better, some cheaper, some both. Here's the honest breakdown.

Why people are leaving Wappalyzer

The complaints aren't new, but they've gotten louder. The current pricing structure:

• Free: 50 tech lookups/month, no API, no CRM
• Pro: $250/month for lead lists and basic features
• Business: $450/month for API access (20,000 credits/month, expiring in 60 days)
• Enterprise: $850+/month

The 60-day API credit expiration is the one that hurts the most. You pay $450/month and then lose unused credits if you don't burn through them fast enough. The old rollover system is gone.

Detection accuracy has also slipped. One Chrome reviewer put it plainly: "When I started using this extension it was really amazing. The results were truly accurate. But now it is just confused." That review has hundreds of upvotes.

So what actually works in 2026? Here are 10 alternatives worth knowing.

1. StackSee (our tool)

Full disclosure: We built this. We started with a tech detection side project and realized the real value wasn't in lookups — it was in enrichment. Sales teams need to know what technologies their prospects use, at scale, in real time. That's what StackSee does.

StackSee is a technographic enrichment API. You input domains (individually, via CSV, or through the API), and get back structured enrichment payloads: CMS, analytics, payments, marketing automation, frameworks, and more. The data is fresh — we scan in real time using a headless browser, not cached crawls from months ago.

Pricing

• 100 free trial requests (no credit card)
• Starter: $39/month for 5,000 requests
• Growth: $99/month for 25,000 requests
• Scale: $499/month for 150,000 requests
• Monthly credits don't expire

What it does

• Real-time technographic enrichment across 2,000+ technologies
• Bulk domain enrichment via CSV upload or REST API
• Structured enrichment payloads: CMS, analytics, payments, marketing automation, frameworks
• AI-powered brand enrichment with company context and social profiles
• Daily data refresh using headless browser scanning (not monthly/quarterly crawls)
• Chrome and Firefox extensions for on-the-fly intelligence
• REST API included from the Starter plan (not paywalled at $450+)
• Export enriched data to CSV, JSON, or CRM

Best for

Sales teams, agencies, and growth teams that need real-time technographic enrichment for prospecting without paying $250+/month for Wappalyzer or $450+/month for API access.

2. BuiltWith

The oldest player in this space, around since 2007. BuiltWith has the deepest historical database of any tool on this list and it shows in the breadth of what it can detect.

Pricing

• No free tier
• Basic: $295/month for 2 technology lists
• Pro: $495/month for 10 lists
• Team: $995/month for unlimited lists (annual commitment)

What it does

• Tracks 109,000+ technologies
• Historical data going back 17+ years (unique in this market)
• Lead generation with advanced filtering
• Market share reports across technology categories
• Ecommerce tracking with sales estimates
• Full API access

Honest take

If you need to know what technologies a domain was running three years ago, BuiltWith is the only real option. For everything else, the price is hard to justify. The interface also feels dated compared to newer tools.

Best for

Enterprise market research and situations where historical data matters.

3. Bloomberry

Bloomberry launched in 2024 and has quickly become one of the more recommended tools on forums like Hacker News. It takes a different approach: instead of just scanning frontend signals, it analyzes DNS records, subprocessor lists, and other signals to find B2B software tools that frontend-only scanners miss entirely.

Pricing

• Free tier: 200 API credits to start
• Paid plans: Contact for pricing (aimed at sales teams)

What it does

• Detects 1,200+ B2B products across 175 categories
• Finds non-frontend tools: CRMs, ERPs, DevOps tooling, security products
• Tracks real-time installs and uninstalls (not just point-in-time snapshots)
• Covers things like which HubSpot vs Salesforce a company uses (useful for SDRs targeting by CRM)

Honest take

If you're doing B2B sales prospecting and want to know what software stack a company runs (not just their website stack), Bloomberry detects things that Wappalyzer simply can't see. It's a different use case from pure frontend detection.

Best for

Sales teams prospecting based on software stack, not just website technology.

4. SimilarTech

SimilarTech is a Similarweb company now, which explains the enterprise pricing. It's a sales intelligence platform where technology detection is one feature among many.

Pricing

• Startup: $290/month for 1 user, 10 reports, 1,000 websites per report
• Professional: $12,000/year for 2 users, unlimited reports
• Premium: $36,000/year for 5 users, web traffic data, firmographics
• Enterprise: Custom (includes API and CRM integrations)

What it does

• Tracks 46,000+ technologies
• Competitor analysis with side-by-side comparisons
• Lead scoring by technology fit
• Market segmentation by industry, company size, and stack
• Salesforce and HubSpot integrations (Enterprise tier)

Honest take

The Startup plan at $290/month is in Wappalyzer territory. The jump to Professional is steep ($1,000/month on annual). If your team is already in the Similarweb ecosystem, it makes sense. Otherwise, the price-to-value for pure tech detection is hard to defend.

Best for

Sales teams at tech companies that are already using Similarweb for web traffic analysis.

5. WhatRuns (free)

WhatRuns has no paid tier, no sign-up requirement, and no API. It's a browser extension that does one thing: tells you what a site is running while you browse it.

Pricing

• Completely free

What it does

• Chrome, Firefox, and Edge extension
• Detects CMS, frameworks, analytics tools, CDNs, WordPress plugins, and fonts
• 450,000+ active users
• "Follow" feature: get alerts when a site changes technologies
• Adds 50-100 new technology definitions daily

Honest take

For quick browsing checks, this is the closest free replacement for Wappalyzer's extension. No account required. Detection quality is solid for common stacks.

Best for

Individual developers, designers, and anyone doing casual one-off lookups.

Limitations

No bulk analysis, no API, no lead generation, no historical data.

6. WhatCMS

WhatCMS does exactly what the name says: identifies what CMS a website runs on. It's API-first and purpose-built for CMS detection at volume.

Pricing

• Free: 500 detections/month via API
• $20/month: 10,000 detections
• $40/month: 20,000 detections
• $80/month: 50,000 detections
• Scales up to $800/month for 1M detections
• No registration required for free tier

What it does

• Detects 1,200+ CMS platforms
• Fast detection (sub-second for cached results)
• Simple REST API with clear documentation
• Private detections on paid plans (results not shared publicly)

Honest take

Very focused. Doesn't detect frameworks, analytics, or infrastructure. But if CMS identification is the only thing you need at scale, the per-detection pricing is about as cheap as this gets.

Best for

Developers building tools that need CMS detection, or researchers auditing CMS adoption at scale.

Limitations

CMS only. No lead generation, no browser extension, no broader tech detection.

7. Snov.io Technology Checker

Snov.io is primarily an email outreach platform. The technology detection piece is one feature inside a larger sales toolkit.

Pricing

• Free browser extension
• Snov.io platform from $39/month (includes email finding, drip campaigns, and tech detection)

What it does

• Technology detection (27,000+ technologies tracked)
• Contact discovery alongside tech data
• LinkedIn integration for lead enrichment
• Email verification built in
• CRM sync

Honest take

If you're already using Snov.io for email outreach, the tech detection is a free add-on. If you're evaluating it as a standalone tech detection tool, you're paying for a lot of email features you don't need.

Best for

SDRs who combine tech stack research with outbound email sequences.

8. CRFT Lookup

CRFT Lookup lives at crft.studio/lookup (the old crftlookup.com domain no longer works). It's a free tool from a web design agency, which means the goal is lead generation for their studio, not a product they're selling.

Pricing

• Completely free
• No registration required
• Unlimited scans

What it does

• Technology detection across 2,500+ fingerprints (uses headless Chromium)
• Google Lighthouse scores for performance, accessibility, SEO, and best practices
• Meta tag previews showing how a site appears in search and social
• Sitemap visualization as an interactive tree view
• Shareable reports (saved for 30 days via unique URL)

Honest take

The combination of tech detection + Lighthouse scores in one free tool is genuinely useful. Most tech detection tools don't touch performance data. CRFT does both without asking for an account. The tradeoff is no API and no bulk analysis.

Best for

Web designers and SEO professionals who want a comprehensive free audit without juggling multiple tools.

9. Hunter TechLookup

Hunter is known for email finding. TechLookup is their directory tool: pick a technology, get a list of websites using it. It runs on Hunter's credit system.

Pricing

• Free: 50 credits/month total across all Hunter features
• Starter: from €34/month for 2,000 credits
• Growth: from €104/month for 10,000 credits
• Scale: from €209/month for 25,000 credits

What it does

• Database of 4.5M+ domains tracking 115 technologies
• Find all sites using a given technology (WordPress, React, Shopify, etc.)
• Filter by website popularity/traffic level
• Company names and social profiles included
• Integrates directly with Hunter's email finder workflow

Honest take

Hunter TechLookup is better described as a prospecting directory than a tech detection tool. You search by technology and get a list of companies. You can't look up a specific URL and get its full stack. If you're already on Hunter for email outreach, this is a useful add-on. As a standalone tool, the 115-technology limit is narrow.

10. StackCrawler

StackCrawler is a free, indie project out of Oslo that focuses on CMS and e-commerce detection. No paid plans, no API, no signup required.

Pricing

• Completely free

What it does

• CMS detection, e-commerce platforms, hosting providers, website builders
• WordPress plugin detection
• CDN identification
• Chrome extension

Honest take

It's lean and free. Good for quick WordPress/Shopify checks. For anything beyond that, you'll hit its limits fast.

Best for

Budget-conscious users who just need basic CMS/e-commerce detection.

Feature comparison

How to choose

For individual developers and designers

WhatRuns or CRFT Lookup. Both free, no signup, good enough for day-to-day browsing.

StackSee at $39-99/month covers most use cases. StackCrawler is an option if you only need basic CMS checks and want to spend nothing.

For sales teams building lead lists

StackSee for real-time technographic enrichment and bulk domain processing. Bloomberry if you need to detect backend B2B tools that aren't visible from the frontend.

For enterprise market research

BuiltWith if you need historical data going back years. SimilarTech if you're already in the Similarweb ecosystem.

For CMS-specific research at scale

WhatCMS. Cheap, API-first, focused.

For teams already using outreach tools

Snov.io if you use their email platform. Hunter TechLookup if you're on Hunter.io.

Switching from Wappalyzer

If you're on the free tier (50 lookups/month)

Install WhatRuns or CRFT Lookup. Takes five minutes. Keep Wappalyzer installed for a few weeks to compare results on the same sites before you delete it.

If you're on Pro ($250/month, API-limited)

Run a parallel test first. Take 50 domains you know well and check them in both tools. Look for discrepancies. StackSee at $39/month covers the same 5,000 lookups at 84% less cost. The API format is different, so budget 2-3 hours for integration updates.

If you're on Business/Enterprise ($450-850/month)

Map what you're actually using: team seats, CRM sync, historical data, API volume. Then match to alternatives. BuiltWith for historical depth. SimilarTech for Salesforce/HubSpot workflows. StackSee for cost reduction at similar volumes.

Before you cancel:

• Export all lead lists to CSV
• Save API credentials and integration code
• Screenshot any custom filters or saved searches
• Run parallel testing for at least two weeks

Common questions

Is Wappalyzer still worth using?

For free-tier casual use (under 50 lookups/month), it's fine. For paid plans, the value proposition has weakened. The $250/month Pro plan is expensive for what you get, and the $450/month API tier with expiring credits is hard to defend when alternatives cover the same ground at lower cost.

Which tool has the most accurate detection?

No tool hits 100%. A SEOmator benchmark put Wappalyzer at 67% accuracy. BuiltWith covers more edge cases from its larger database. Newer tools like StackSee and Bloomberry tend to catch modern frameworks faster. For critical findings, cross-reference two or three tools rather than trusting one source.

Can these tools detect Shopify apps?

StackSee and StackCrawler both have specialized fingerprinting for Shopify app detection. General tools like WhatRuns can catch some apps but miss many. If Shopify app intelligence is your main use case, use a dedicated tool.

How do I know if the data is fresh?

Check the tool's update cadence before relying on it for outbound prospecting. WhatRuns and CRFT Lookup detect in real-time. StackSee and StackCrawler refresh daily. Wappalyzer, SimilarTech, and Hunter TechLookup refresh monthly. BuiltWith is quarterly. Monthly data can easily miss a recent technology migration.
