Seven options compared by what you were actually buying: lead lists, one-off lookups, an enrichment API, or hiring-based technographics. ![Dvir Atias](/authors/dvir-atias.jpg) Dvir Atias Founder, JobsPipe BuiltWith is the incumbent of technology profiling: it has crawled the web for the better part of two decades, tracks tens of thousands of technologies, and its lead-list business - “give me every site running Shopify Plus in Germany” - is the reference product for technology-based sales prospecting. It is genuinely good at coverage and history, and its pricing reflects it: the lead-list plans run hundreds of dollars a month, billed for the whole machine whether you need it or not. That last part is why people search for alternatives. In our experience the searches split into four different buyers: teams that want **lead lists**, developers that want a **lookup API** for one domain at a time, people who just want a **free one-off check**, and sales teams that actually want to know **what a company is adopting** - which detection from a homepage can only partly answer. Be clear which one you are before you shortlist. Disclosure up front: JobsPipe sells a tech-detection API (the Stack Scan endpoint), so we compete in exactly one of the four categories. For lead lists at BuiltWith scale we will point you elsewhere. ## Which alternative fits what you were buying | You were buying BuiltWith for | Closer-fit alternative | | --- | --- | | Lead lists by technology | HG Insights, SimilarTech, ZoomInfo (Datanyze) | | Per-domain lookup API | JobsPipe Stack Scan, Wappalyzer API | | Free one-off checks | WhatRuns, Netcraft site report, browser extensions | | Self-hosted detection | Open-source Wappalyzer forks | | What a company is adopting, not just serving | Hiring-based technographics (job postings) | ## The options **Wappalyzer** is the closest like-for-like: the same fingerprinting idea, sold as a browser extension, lookup tools and a metered API. It has its own trade-offs - the project went closed-source and the API is credit-priced - which we cover in a dedicated [Wappalyzer alternatives](/blog/wappalyzer-alternatives) comparison. **HG Insights, SimilarTech and Datanyze (ZoomInfo)** are the lead-list competitors. If your actual product is a prospect list filtered by installed technology, these are the direct substitutes, priced for sales teams and sold as platforms. HG leans enterprise IT spend intelligence; SimilarTech leans web technologies; Datanyze now lives inside ZoomInfo's suite. **WhatRuns and Netcraft** cover the free end. WhatRuns is a lightweight extension with a surprising hit rate on modern frameworks; Netcraft’s site report is the veteran for hosting, certificates and infrastructure detail on a single domain. **JobsPipe Stack Scan** is the developer-shaped option: one POST with a domain returns the detected stack - frameworks, analytics, CDNs, payment and SaaS widgets - as JSON with confidence scores and category labels, scanned live and cached about two weeks. Self-serve key, free tier, metered per job like the rest of our API. It scans one domain per call: it is an enrichment primitive for your product or pipeline, not a lead-list factory. ## The blind spot every homepage scanner shares Detection - BuiltWith’s, Wappalyzer’s, ours - sees what a company _serves on its public website_. It cannot see the data warehouse, the internal tooling, or the platform migration that started last quarter. The public signal for those is hiring: job postings name the technologies a company is actually investing in, often before anything ships. That is a different data layer - technographics from [job postings](/blog/job-postings-dataset) - and pairing a homepage scan with a company’s posting history (both of which JobsPipe exposes) answers the question sales teams are really asking: not “what is on their site” but “what are they betting on next”. Need tech detection as an API? One POST per domain, free tier, key in 30 seconds. ![](/listly/shape-heart.png) FAQs ## Frequently Asked Questions ### What is the best alternative to BuiltWith? It depends on which part of BuiltWith you were using. For technology-filtered lead lists, HG Insights, SimilarTech and Datanyze (inside ZoomInfo) are the direct competitors. For a per-domain lookup API, JobsPipe Stack Scan and the Wappalyzer API are the developer-shaped options. For free one-off checks, WhatRuns and Netcraft's site report cover most needs, and open-source Wappalyzer forks handle self-hosted detection. ### Is there a free alternative to BuiltWith? For manual checks, yes: the WhatRuns browser extension and Netcraft's free site report handle single domains well, and open-source fingerprint libraries can be self-hosted without licence fees. For API access, free tiers rather than free products are the norm - JobsPipe's Stack Scan includes free monthly requests on the same key as its jobs API. ### What can a technology-detection tool not see? Anything not served on the public website: internal tooling, data warehouses, self-hosted software behind the firewall, and migrations in progress. The public signal for those is hiring - job postings name the technologies a company is investing in, often before anything ships. Pairing a homepage scan with a company's job-posting history covers both what is live today and what is being built next. ### How does JobsPipe Stack Scan compare to BuiltWith? Stack Scan is a per-domain enrichment API: one POST returns the detected technologies as JSON with categories and confidence scores, from a live scan cached about two weeks, on a self-serve key with a free tier. BuiltWith's strength is breadth and history - long-term tracking and lead lists across the whole web - at prices built for sales teams. For enriching domains inside your own product, the API shape wins; for buying prospect lists, BuiltWith's category wins.
