Wappalyzer alternatives: pick one per product, not one per vendor
Wappalyzer sells lookups, lead lists, email verification and alerts. The alternative that replaces each one, with prices read today, plus the free routes.
ListNovember 12, 2026 · 11 min read
Most "Wappalyzer alternatives" lists compare it to whole products, which is the wrong unit. Wappalyzer is four things sold in one account: a single-site technology lookup, lead lists built from a technology, email verification, and website alerts. Almost nobody uses all four, so the right alternative is the one that replaces the one you use. ShopLeads is our product, so we say so; everything else here is described from its own page, read on November 9, 2026.
Two facts set the frame. Its technology directory lists 8,189 web technologies across 106 categories and describes detection as looking for public signals on websites: HTML, scripts, headers, cookies and other fingerprints. And its API documentation opens with a line worth reading before you plan anything: a Business plan is required to use it.

Why people look for a Wappalyzer alternative
The lookup is no longer anonymous. We requested a single-site lookup without signing in on November 9, 2026 and got a sign-up form. A free account covers 50 lookups a month, which is fine until it is not.
The API is gated by plan, not by usage. Pro at $250 a month includes one user, two lead-list technology targets and no API credits; the API and CRM enrichment start on Business at $450 (pricing).
Credits expire. Credits included in a plan expire after 60 days and credits bought in bundles after 365 (pricing).
E-commerce depth is shallow at the app level. Its add-ons section lists 181 Shopify apps and 3 Shopify themes, which is the right order of magnitude for a general web index and the wrong one for selling to merchants.
Backend software is invisible to it, as it is to every website crawler. An ERP, an HR system or a security stack leaves no mark on a storefront.
You want the detection in your own code, on your own schedule, with no per-lookup meter.
The alternatives, product by product

ShopLeads
Replaces: lead lists, when the lead is an e-commerce store
Wappalyzer is built around a lookup: you arrive with a domain and leave with its stack. This is built around the opposite motion, where you arrive with a description of a customer and leave with the list. You do not type a domain at all — you say Shopify, apparel, 1M-10M a month, running Klaviyo but no reviews app, and the matching stores come back already paired with the people who run them. Each store has been scanned and put through rules and an AI check, so the brands in that list are real DTC brands rather than resellers.
List-first, not lookup-first: a count comes back before any rows do, so you learn whether a segment is a handful of stores or a quarter's worth of pipeline before spending anything on it.
The filters that describe a buyer rather than a stack: monthly sales bands from 10k-100k up to 10M+, category and micro-niche, country, product keywords, social following, and tech gaps stated as absences such as no reviews app or no loyalty program.
Installed apps and technologies are still there by exact name — that part works the way you already expect — now joined by people: seniority from owner down to manager, about 30 departments, titles to include or exclude, and whether the work email has been checked.
Searching and counting are free and never reveal a contact; credits go only on an unlock, with the exact cost previewed free first. The REST API and MCP server take the same filters and cost nothing to search or count through. Open signup: a 7-day trial with 500 free credits and a card.
Replaces: lookups, lead lists and the API, at a higher floor
Take the free lookup first, because that is the piece of Wappalyzer most people are actually replacing: BuiltWith says single-site lookups are free forever, with no extension to install and no monthly allowance to run down (BuiltWith plans). If your technology is not e-commerce-specific it is the closest like-for-like swap in this list, and the one you can test before you decide anything.
Where the paid tiers land: Basic $295, Pro $495 and Team $995 a month, with Basic capped at 2 technologies, 2 keywords and 2 retail reports, so the cheap tier answers one fixed question rather than a changing one (plans).
The scale behind the lookup: 491.9 million domains, 128,274 technologies and history going back 41 years, plus exportable contact names, emails and titles for people publicly listed with a business on every plan (plans).
On method it says it indexes the internet the way a search engine does and takes no data from third parties — a crawl-and-recrawl trade-off rather than fingerprint matching, so freshness is a schedule rather than a page load.
Replaces: lookups and lists, when your technology is not on any menu
This is the one to reach for when Wappalyzer's 8,189 named technologies do not include yours — a competitor's script tag, a snippet nobody has fingerprinted, a string only your integration leaves behind. Instead of picking a detection from a menu you write the query: HTML, JavaScript, CSS, HTTP headers, cookies and XHR URLs, combined with AND, OR and NOT. Its crawler fully renders pages, so tag-manager-injected scripts count (NerdyData pricing).
Basic $100, Pro $300 and Teams $600 a month, with a free account unlocking up to 100 rows per report. API access is pay-as-you-go and not included with a subscription (pricing).
Pick it when your product leaves a distinctive string on a page that nobody has turned into a named detection.
Two of Wappalyzer's four products, at no cost and with no account: the single-site lookup, and the alert when a site you follow starts or stops using something. That is the pair most individual users were on the free plan for, which makes this the cheapest honest answer to the 50-lookups-a-month ceiling. Its homepage claims 450k+ active users and says 50 to 100 new web apps are added a day (WhatRuns).
It covers two of Wappalyzer's four products at no cost, and none of the other two: no list builder, no export, no verification.
If the technology you sell against is a Shopify app rather than a JavaScript library, this is the gap that matters. Store Leads counts 13,990,637 active stores across 421 platforms, with 9,098 apps and 1,006 technologies tracked, 40-plus attributes per domain and a weekly refresh (Store Leads).
Premium $75, Pro $250, Elite $450 and Enterprise $950 a month. Premium and Pro cover any two platforms, exports and API start at Pro, and historical data is Enterprise only (Store Leads).
Its contact data is store-level and non-personal by its own description, with personal contact data available through a third-party integration you enable yourself.
Replaces: lead lists plus contacts, for Shopify sellers
Both are Shopify-first subscriptions that include contact unlocks in the same account, which Wappalyzer does not do for lists. StoreCensus reports 5M+ stores tracked and 8,300+ Shopify apps indexed, and routes matching stores into Apollo, Instantly, Smartlead or Zapier (StoreCensus pricing).
StoreCensus: free tier, then Starter $49, Professional $99 and Growth $149 a month. Starter is Shopify only and has no decision-maker contacts; WooCommerce, decision-maker unlocks and the API start at Professional (pricing).
StoreInspect: 10 free contact reveals a month, then Pro $99, Business $249 and Scale $599, priced in reveals rather than credits. API and MCP start at Pro (pricing).
Replaces: alerts, with dated events instead of presence
Website detection tells you a tool is present. These two tell you when it arrived. Bloomberry's docs describe an API from Revealera covering 1,700+ B2B products across 190 categories, detected from new subdomains, DNS records, certificate transparency logs and per-product deployment signals rather than page scanning, with a free API key of 1,000 credits to test (Bloomberry docs).
PredictLeads publishes pay-as-you-go pricing: 100 free API calls a month, then tiers from $0.04 down to $0.002 per credit with a $40 minimum monthly charge, and credits that do not roll over (PredictLeads pricing).
Both answer "why now", which is the question a technology list cannot answer at all.
This is the part the sales-oriented lists leave out. The original Wappalyzer open-source project went private in August 2023, and enthec/webappanalyzer continues the fingerprint set under GPL-3.0, as a long list of regular expressions over HTML, JavaScript variables and response headers. Its main branch had 977 commits and a merge dated November 3, 2026 when we looked.
s0md3v/wappalyzer-next is a command-line tool and Python library that drives the real Wappalyzer browser extension inside Chromium through Playwright, which sidesteps the stale-fingerprint problem the pure ports have. Its latest release was 2.0.4, dated September 30, 2026.
You get no company data, no contacts and no index: you get detection, on your machine, with no meter.
What Wappalyzer still does that none of these replace
Three things, and they are the reason to stay if you use them. Email verification sits in the same account as the list, so a technology list comes out already checked. Website alerts watch specific sites on the free tier. And its lead-list builder lets you review a free sample before you download the full list, which is a rare and genuinely useful way to test coverage before paying. It has also been at this since 2008, which is longer than most of this page (About Wappalyzer).
The lookup you can run on any store without an account
Before you shortlist anything, see what a page gives up on its own. Detection is fingerprint matching, and you can do the matching:
Run on Olipop on November 9, 2026 that returned six app names: Klaviyo, Gorgias, Recharge, Rebuy, Triple Whale and Elevar. Two cautions. A brand that serves its scripts from its own CDN will show you almost nothing this way, and a paid index will not do better, because the fingerprints are not in the page to find. And a page that answers a browser but not a script is a page you cannot automate: treat an empty result as "unknown", not "nothing installed".
Do this on three stores you already know well. If the tool you are evaluating returns the same names you just found for free, you are buying the list builder, the export and the refresh schedule rather than the detection. That is worth money, as long as you know which one you are buying.
From a technology match to the decision-maker
Every option above hands you domains. Turning domains into replies is the same sequence whichever one you picked.
Choose a signal that holds up. An installed app, a missing app, or a monthly sales band survives a redesign; a theme or a framework does not.
Narrow to stores that could actually buy: your platform, a sales band that can afford you, a category you understand.
Lead with the gap, not the rival. "No loyalty program" opens better than "uses a competitor".
Add the person before you export: decision-makers only, in the departments you sell to, with a work email whose status you can see.
Pay last. Searching and counting should be free, so narrow for free and spend only on the people you will write to.
Yes, for lookups. WhatRuns is a free browser extension with no sign-up, BuiltWith is free forever for single-site lookups, and the open-source fingerprint set at enthec/webappanalyzer lets you run detection yourself. None of the free options build lead lists or verify email addresses.
Is Wappalyzer still free?
A free account is, within limits. It covers 50 technology lookups and 50 email verifications a month, 5 website alerts and free sample lead lists. We requested a single-site lookup without signing in on November 9, 2026 and were asked to create an account first.
Does Wappalyzer have an API?
Yes, but it is tied to a plan rather than sold by usage. Its API documentation states that a Business plan is required, which is $450 a month on its pricing page. Credits included in a plan expire after 60 days.
Which Wappalyzer alternative is best for finding Shopify stores?
An e-commerce index rather than a general web tool, because the app-level depth is different by an order of magnitude: Wappalyzer lists 181 Shopify apps, while Store Leads tracks 9,098 apps and StoreCensus reports 8,300+ Shopify apps indexed. ShopLeads, our product, adds the decision-makers to the same search.
Why does Wappalyzer miss technologies on some sites?
Because fingerprint matching can only see what the page serves. Brands that proxy app scripts through their own CDN hide the third-party signatures every detector looks for, so a large, well-built store can come back almost empty. An empty profile means unknown, not absent.
