We Tested 6 BuiltWith Alternatives – Here Are the Top Picks

BuiltWith has been the default technology-lookup tool for over a decade. Marketers, founders, and sales teams use it to find out what CMS, hosting provider, analytics stack, or payment processor is running behind any website. It's reliable, it's comprehensive, and it's been around long enough to become a verb — "just BuiltWith it."

But BuiltWith isn't the only option anymore, and at roughly $295/month to get started, it's far from the cheapest. If you're hunting for a cheap BuiltWith alternative or even a free BuiltWith alternative, a real market has grown around it — tools that cost a fraction of the price, and in some cases do more with the data once you have it.

We tested six alternatives head-to-head, evaluating each on detection accuracy, lead-generation depth, pricing transparency, and how usable the data actually is once it lands in your hands. Below is what stood out, what fell short, and which tool makes sense depending on what you're trying to accomplish.

The most common trigger is price. BuiltWith's plans start near $295/month, and the features that actually matter for most teams — lead lists, bulk lookups, API access — sit further up the pricing ladder than that. For a solo founder or small agency, that's a steep entry cost just to find out what tech stack a prospect is running.

Then there's the "so what" problem. BuiltWith is excellent at telling you what a site is built with. It's less good at turning that information into something you can act on — a filtered list of leads, an outreach-ready export, or a signal about when a company actually started (or stopped) using a product. Several newer tools built lead generation and outreach directly into the core product instead of treating it as an add-on.

Detection scope is another factor. Traditional tools like BuiltWith only see what's visible in a site's public code — scripts, headers, markup. They can't tell you a company just adopted a new CRM or churned off a security vendor, because that activity never touches the website. Teams doing serious go-to-market work increasingly want that layer too.

TechPeeker is a technology detection and lead generation platform built for marketers, agencies, and sales teams. It doesn't stop at identifying what a site runs — it lets you turn that detection into targeted prospect lists through keyword search, filtering, and bulk export. An API is available for teams who want technographic data flowing directly into their own tools.

What makes it different is that the workflow ends in a usable lead list, not just a tech report.

Wappalyzer is probably the most recognized name in this list, largely thanks to its browser extension — install it once and see a site's tech stack the moment you land on the page. Paid plans extend that into bulk lookups, change alerts when a site's stack shifts, and CRM-ready lead exports.

What makes it different is how effortless the extension makes casual, one-off lookups, with a clear upgrade path if you need more.

WebTechSurvey keeps things simple: technology detection, lead list generation, and export, without a lot of extra surface area to learn. Every plan includes unlimited lookups and API access, which is unusual — most competitors gate the API behind a higher tier.

What makes it different is there are no feature-gating games. What you see in the pricing table is what you get.

Bloomberry takes a different approach entirely. Instead of only reading what's visible in a site's public code, it reads infrastructure signals like new subdomains and DNS records, tracking subscribe and churn activity across more than 1,700 B2B products — CRMs like Salesforce and HubSpot, HR platforms, security tools, and more — including tools that never show up on a website at all. You get alerted when a target company adopts or drops something in your category.

What makes it different is that it's the only tool here that surfaces buying signals BuiltWith-style detection simply can't see.

Snov.io is fundamentally a sales and outreach platform, with domain search and technology lookup features layered in. The value isn't the tech detection alone — it's that research, email finding, verification, and campaign launch all live in the same dashboard.

What makes it different is it collapses "find the lead" and "reach the lead" into one workflow.

Web Reveal is the lightest-weight option on this list. Its free Chrome extension and single-site scanner reveal the CMS, frameworks, hosting, analytics, and plugins behind a site using publicly visible signals — HTML, scripts, HTTP headers. A paid Bulk Scanner extends that to up to 100 domains a day with CSV export, and it also publishes public technology trend rankings pulled from its scan database.

What makes it different is it's free for casual use and cheap for bulk use, with no lead-gen ambitions muddying the product.

Not every team needs — or can justify — a paid subscription right away. A few options here hold up well at $0.

Web Reveal is the most complete free option: unlimited single-site lookups through its Chrome extension, with no credit card required. You lose bulk scanning and CSV export until you upgrade, but for occasional lookups it's hard to beat.

Wappalyzer's free tier covers the browser extension for casual, one-at-a-time lookups — useful if you just want a quick answer while browsing rather than building lists.

Bloomberry's free trial requires no credit card, enough to evaluate whether buying-signal tracking is worth paying for before committing.

BuiltWith's enterprise tiers, along with the higher plans from tools like Wappalyzer, are priced for organizations where the data clearly pays for itself. For everyone else, there's a real gap between "free extension" and "$850/month enterprise contract" — and that's exactly where most of this list lives.

TechPeeker and WebTechSurvey both offer unlimited lookups starting under $150/month, with API access included well below what BuiltWith or Wappalyzer charge for the same capability. Bloomberry undercuts traditional enterprise intent-data platforms at $199/month while tracking a category (subscribe/churn signals) those platforms often charge far more for. Snov.io stays affordable at the low end specifically because it's credit-based — you only pay for the volume you actually use.
