10 Best Wappalyzer Alternatives in 2026 (Tested)

10 Best Wappalyzer Alternatives in 2026

Wappalyzer gives you 50 free lookups a month. The first paid plan on the official pricing page is $250/mo for Pro. And the part that really stings: those API credits expire after 60 days, whether you've used them or not. If you're paying for tech detection and leaving credits on the table, you're subsidizing Wappalyzer's business model, not yours.

The tool itself is solid - 4.7/5 on G2 with 55 reviews, and users consistently praise its ease of use. But the top complaints? "Limited Credits" and "Plan Limitations." That tracks. Wappalyzer is best known for frontend tech detection, and it only detects what it can observe from the website itself. Backend systems like databases and server-side frameworks tend to land around 15-25% accuracy. If you're prospecting based on backend adoption - say, a CRM that doesn't expose clear frontend signals - Wappalyzer can easily miss it.

These alternatives solve that, and most go further than basic tech lookups.

Our Top Picks

If you just need to identify what a website runs, WhatRuns or CRFT Lookup cost nothing. If you need to turn tech intelligence into pipeline, Prospeo collapses the entire workflow - detection, contact data, verification - into a single search. And if you need the deepest historical technographic database on the planet, BuiltWith is still unmatched.

Pricing at a Glance

Two things jump out. BuiltWith Basic at $295/mo for just 2 technologies is borderline insulting - you're paying nearly $150 per technology tracked. And Wappalyzer's 60-day API credit expiration penalizes inconsistent usage, which is exactly how most sales teams use tech detection tools: in bursts, not daily.

Let's be honest: if your average deal size sits below five figures, you probably don't need BuiltWith or Wappalyzer Pro at all. A free extension plus a solid contact data tool will outperform an expensive technographic database that sits unused between campaigns.

Best Wappalyzer Alternatives Reviewed

Prospeo - Tech Detection to Outreach

You don't just want to know what a company runs - you want the CTO's verified email and direct dial in the same search. Prospeo's 30+ search filters include technographic filtering, so you can find companies by the technologies they use, then immediately pull from 300M+ professional profiles with 143M+ verified emails at 98% accuracy and 125M+ verified mobile numbers with a 30% pickup rate.

The real value is workflow compression. Instead of exporting a tech list from one tool, hunting for emails in another, and verifying in a third, Prospeo handles the entire chain. Data refreshes every 7 days - about 6x faster than the 6-week industry average - so you're not emailing people who changed jobs last month.

For deep historical technographic research spanning decades, pair it with BuiltWith. Prospeo's strength is turning today's tech intelligence into tomorrow's booked meetings.

Free tier gives you 75 verified emails and 100 Chrome extension credits per month. No contracts, no credit expiration.

BuiltWith - Biggest Database, Steepest Learning Curve

BuiltWith tracks 414 million domains across 111,904 technologies with weekly updates and historical data stretching back 41 years. For market research, competitive analysis, or building massive prospect lists by technology, nothing else comes close. Community posts on Reddit consistently point to BuiltWith as the go-to for raw database size - it has 3-4x more sites for any given technology compared to Wappalyzer, thanks to its crawler-first approach.

Skip this if you're a small team or solo SDR. Basic costs $295/mo and only lets you track 2 technologies with 2,000 domain uploads per month. Pro at $495/mo unlocks unlimited technologies and 20,000 uploads. Team runs $995/mo. There's also a $144/yr Advanced tier for individual detailed lookups - buried in their knowledge base, not on the main pricing page. The interface has a learning curve that'll cost you a few hours upfront, and we've seen teams abandon it within a month because nobody wanted to figure out the export workflow.

NerdyData - Regex Search Across Source Code

NerdyData searches HTML, third-party scripts, cookies, and code fingerprints. It fully renders JavaScript before scanning, catching dynamically loaded technologies that signature-based scanners miss entirely. Want to find every site with a specific tracking pixel, custom integration, or code snippet? Regex search across source code is NerdyData's killer feature - no other tool on this list does it.

In our experience, it's most useful for agencies doing competitive intelligence or developers hunting for specific implementation patterns. Free tier gives you 50 rows per report. Basic runs $200/mo with 5,000 rows per download, Pro $300/mo with 200,000 rows, Enterprise $1,000/mo. G2 rating is 4.3/5 but with only 2 reviews - not enough to draw conclusions from.

Skip this if you want a simple browser extension for quick lookups. NerdyData is a power tool, not a casual scanner.

Bloomberry - Backend and B2B Tool Detection

Bloomberry fills Wappalyzer's biggest blind spot. It tracks over 1,200 B2B products that never show up in page source - CRMs, project management tools, AI products, DevOps platforms, and more. If you're prospecting based on backend technology adoption, this is the only tool on the list purpose-built for that use case.

Free trial available, paid plans from $199/mo with API access included. The database is narrower than BuiltWith's, but it covers a completely different layer of the stack. We've found it particularly useful when targeting companies running specific internal tools that are invisible to every frontend scanner on this list.

WhatRuns - Best Free Browser Extension

WhatRuns is unmatched for font, color, and WordPress theme identification. Install the extension, click, done. Premium is $9/mo, but the free tier handles most casual use cases.

Skip this if you need API access, bulk export, or anything resembling lead generation. WhatRuns doesn't offer any of that. It's a visual inspection tool, not a prospecting engine.

Snov.io - Sales-Oriented With Email Credits

Starter runs $29.25/mo on annual billing with 1,000 credits, Pro $74.25/mo with 5,000 credits. Each email verification or prospect lookup costs 1 credit. Tech detection bundled with email finding and outreach sequences in one credit-based system sounds appealing - until you do the math.

Credits burn fast when every action costs one, and adding LinkedIn automation is another $69/mo per seat. At scale, the per-contact cost climbs well above $0.01/email, and Snov.io's email database is smaller than dedicated data platforms. Best for small teams running low-volume outbound who want everything in one dashboard.

SimilarTech - Enterprise Technographics

SimilarTech positions itself as an enterprise-grade technographic platform: Startup at ~$290/mo, Professional at ~$12K/yr, Premium at ~$36K/yr, and custom Enterprise tiers. The technology alerting features are genuinely useful for teams already in the ecosystem, but enterprise pricing for a product with just 12 G2 reviews and an inactive profile is a tough sell. The pricing data is directional - last publicly updated in 2021 on SaaSWorthy - so expect it's shifted since then.

CRFT Lookup

CRFT Lookup is free and unlimited - no account required. It bundles Lighthouse performance scores alongside tech detection, making it great for quick site audits. Not a prospecting tool, but the fastest path to "what does this site run?"

Stackcrawler

Stackcrawler offers 30 free profilings per month with paid plans from $19/mo - the cheapest paid option on this list. The database is limited compared to BuiltWith or NerdyData, but for budget-conscious teams doing occasional lookups, it's a reasonable entry point.

WhatCMS

Free for individual CMS lookups, with API access from $99/mo. If you only care about content management systems - WordPress, Shopify, Drupal, Webflow - WhatCMS is focused and affordable. Skip it if you need broader technology detection.

From Tech Stack to Booked Meeting

Here's the thing most tool comparisons won't tell you: the workflow SDRs actually live through is brutal. You build a list of 500 companies using HubSpot from BuiltWith. Export the CSV. Spend three hours cleaning it - deduplicating, fixing formatting, removing dead domains. Then you realize there's no contact information. Not a single email. Not a single phone number.

So you open Hunter or Snov.io, start feeding in domains one by one, burn through credits, get a mix of verified and catch-all emails. Then you need a separate verification tool to clean the list before loading it into your sequencer. The "free" tech lookup just cost a full day of SDR time and $200+ in tool subscriptions. I've watched this exact cycle play out at three different companies before we finally consolidated the stack.

Prospeo's technographic filters cut this entire chain. Search by technology, filter by job title and company size, export verified emails and direct dials - all without leaving the platform. One search replaces the BuiltWith export, email finder, verification tool, and CRM enrichment chain.

What Wappalyzer Can't Detect

Wappalyzer is strong at detecting technologies that expose clear frontend signals. But if a tool doesn't show up in the HTML, JavaScript variables, or response headers, it's invisible.

Most technologies that load a script tag or set an HTTP header are easy to detect. But if a technology doesn't expose itself through observable frontend signals, it's invisible to signature-based scanners.

For backend detection, Bloomberry is purpose-built with 1,200+ B2B products tracked. For code-level detection, NerdyData's regex search catches what signature-based tools miss entirely.

Wappalyzer Alternatives FAQ

Is there a free alternative to Wappalyzer?

WhatRuns and CRFT Lookup are both completely free for one-off tech lookups - no account required for CRFT, no credit card for WhatRuns. Prospeo also offers a free tier with 75 verified emails and 100 Chrome extension credits per month, which adds contact data on top of tech detection.

Does Wappalyzer detect backend technologies?

Poorly - roughly 15-25% accuracy for databases, server-side frameworks, and internal tools. It relies on frontend signals like scripts, meta tags, and HTTP headers. Bloomberry tracks 1,200+ B2B backend products specifically, and NerdyData's JavaScript rendering catches dynamically loaded technologies that signature-based scanners miss.

Why is Wappalyzer so expensive?

The free tier caps at 50 lookups/month, and Pro jumps to $250/mo for 5,000 lookups. The real cost driver is the 60-day API credit expiration - unused credits vanish, effectively raising the per-lookup cost for teams that use tech detection in campaign bursts rather than daily.

Can I get tech stack data with verified contact info?

Prospeo is the strongest option here: technographic filters combined with 143M+ verified emails at 98% accuracy and 125M+ direct dials in a single search. Snov.io bundles tech detection with email finding but has a smaller database and a credit model that gets expensive past a few hundred contacts per month.

What's the best BuiltWith alternative for small teams?

BuiltWith Basic costs $295/mo for just 2 technologies - prohibitive for most small teams. NerdyData at $200/mo with 5,000 rows per download or Stackcrawler at $19/mo offer more accessible entry points for pure tech detection without the enterprise price tag.
