Best Technographic Data Providers in 2026: 13 Tools for Sales Teams and Site Lookups

By Laurel · Updated Oct 22, 2026

If you sell to companies that run a specific tool, BuiltWith and Wappalyzer are the fastest way to a list of websites using it, and HG Insights, ZoomInfo and Enlyft go deeper on company-level install base. If you only need to see what one website runs, a free extension (Wappalyzer, WhatRuns) or W3Techs does the job at no cost. Nobody buys "technographic data" in the abstract. A sales team wants a list of accounts with a particular CRM, cloud or payment tool installed. A developer or marketer wants the stack behind one URL. Those are two different jobs, and the tools below split along that line.

That split is why most roundups mislead. They rank a $295-a-month list builder next to a free browser extension as if both solved the same problem. We sort every tool by the reader it actually suits, then compare it on three things that decide whether the data is any good: how it detects technology, what it costs on the vendor's own price page, and what you need to think about on compliance.

This page is about technology-install data specifically. For the wider category of buyer data, intent signals and contact data, start with the best sales intelligence tools in 2026, and for company and contact records see the best B2B data providers.

Key Facts

• Salesforce's State of Sales report puts selling at 40% of a rep's workweek, with 60% spent on other work, which is the case for pre-filtering lists by installed technology instead of prospecting blind.
• The same report says reps spend almost one full day of the workweek on prospecting.
• BuiltWith says it tracks 127,890 different web technologies across 491.9 million domains (vendor claim).
• Median tenure with a current employer is 4.1 years, per the US Bureau of Labor Statistics, so the contact attached to any tech-install record goes stale on a similar clock.
• TheirStack lists 51M technographics records alongside 225M job records (vendor claim).

Two readers, one label

Technographics means data about the technology an organization uses. The same label covers two very different products.

If you're the first reader, your real purchase is a list-building and enrichment workflow. If you're the second or third, you probably need a free tool and should stop reading the price tables.

Quick Comparison Table

How technographic data is actually detected

This is where accuracy lives, and vendors are uneven about publishing it. There are three detection styles.

1. Front-end fingerprinting. A crawler or browser extension reads a page's HTML, scripts, headers and cookies and matches them against known patterns. W3Techs is the clearest about it: it says it searches pages for specific patterns, using regular expressions and DOM traversal, with several thousand indicators. This is accurate for anything that leaves a trace on a public page (CMS, analytics, ecommerce platform, chat widget) and blind to anything that doesn't (internal CRM, ERP, back-office tools).
2. Inferred or install-base signals. Job postings, customer testimonials, partner listings and integration data hint at tools that never touch a public page. TheirStack builds from job postings, and its pricing page lists 352k job sources across 195 countries. Enlyft says it models an Intelligence Graph in-house rather than borrowing from a data-sharing network, though it doesn't publish the underlying sources.
3. Blended. ZoomInfo's own blog says its coverage spans 30,000+ technologies across 200+ categories, but that page describes industry collection methods generally and doesn't say which ones ZoomInfo uses.

The practical test: ask the vendor which signal produced a given record. If it's "we saw a script on their site", the record is as good as that crawl's freshness. If it's "a job post mentioned it", the record shows intent to hire for a skill, not proof of production use.

1. BuiltWith: the default for lists of websites by technology

BuiltWith is the best-known name for sales teams that need a list of websites using a specific tool. The vendor's plans page claims 491.9 million domains and 127,890 technologies tracked, with history going back 41 years (vendor claims). If its price floor is the problem, the BuiltWith alternatives page sorts replacements by reader, and the free website technology checkers roundup covers one-off lookups.

Pricing is flat per account, not per user. Basic is $295/mo or $2,950/yr with 2 technologies, 2 keywords and 1 login. Pro is $495/mo or $4,950/yr with unlimited technologies and keywords. Team is $995/mo or $9,950/yr with unlimited Pro logins. Annual billing is cheaper than monthly. Individual site lookups are free, according to the vendor.

Best for: sales and marketing teams building outbound lists from installed technology, agencies pitching site owners. Not ideal for: teams that need company-level records on tools that leave no web trace.

2. Wappalyzer: the free extension with a paid lead-list side

Wappalyzer serves both readers in this article. The extension is free, and Wappalyzer says it turns public web signals into technographic data across "thousands of web technologies across millions of websites", available through its site, APIs, extension and bulk data (vendor claims). We compare its closest replacements in the Wappalyzer alternatives.

Paid plans on its pricing page: Pro $250/mo, Business $450/mo, Enterprise from $850/mo, all billed monthly. Annual billing saves 17%; ask Wappalyzer for the annual figure. A free account includes 50 technology lookups and 50 email verifications a month. Pro gives one user and 2 lead-list technology targets; Business gives 5 users and unlimited targets plus CRM enrichment.

Best for: developers and marketers (free), SMB sellers starting list-building (paid). Not ideal for: enterprises that need account-level install data beyond the website.

3. HG Insights: enterprise install base and technology spend

HG Insights sits at the other end of the market from a browser extension. Its pricing page lists Starter, Growth and Enterprise plans with seats, Intelligence credits and leads processed, and says coverage runs to 70M+ companies (vendor claim). The standard term is two years, with one-year at a higher price, and there's no free trial. Vendr reports a median of $90,000 a year (low $31,498, high $173,119, 46 purchases) (reported). HG Insights acquired TrustRadius, announced 19 June 2025.

Best for: enterprise strategy and sales-ops teams sizing a TAM by technology. Not ideal for: small teams or anyone who needs a free pilot first.

4. 6sense: technographics as one signal inside an intent platform

6sense lists "verified B2B data and technographics" as part of a wider signal foundation, so don't treat it as a technology database you can buy alone. Pricing is on request across three packages, and credits unlock emails, phones and records. Vendr reports a median of $62,000 a year, low $11,183, high $176,213 across 387 purchases (reported). The pricing page shows no free plan.

If you're evaluating it mainly for technology filters, read the best 6sense alternatives first, and for how intent and install data interact see our intent data guide.

Best for: ABM teams that want tech fit and in-market behavior in one scoring model. Not ideal for: anyone who only needs a technology list.

5. Demandbase: account intelligence with an ad and sales layer

Demandbase sells a platform, and technology data is one part of its account profile. Its pricing page describes a platform fee plus a flat fee per user, with Advertising and Data sold as standalone products. Vendr reports a median of $68,591 a year, low $24,000, high $164,037 across 187 purchases (reported).

Best for: ABM teams that run advertising and sales plays off the same account list. Not ideal for: small teams buying technology data only.

6. ZoomInfo: technology filters on a contact database

ZoomInfo's technology filters sit on top of its contact and company data. Its own blog says coverage spans 30,000+ technologies across 200+ categories (vendor claim). Pricing is on request, by features, licenses and credit usage, where one credit equals one export of a contact or company profile. Vendr reports a median of $33,500 a year, range $7,240 to $156,042, 1,577 purchases (reported). A free ZoomInfo Lite tier exists for business email users, per the pricing page. For alternatives, see the best ZoomInfo alternatives.

Best for: sales teams that want tech filters and verified contacts in one subscription. Not ideal for: buyers who only need domain-level tech lists.

7. Apollo.io: a technology filter inside a prospecting tool

Apollo is the budget path for sellers. It has a technology filter on company search, so a seller can build a list by installed tool and enrich it in the same account. The data page claims 240M+ contacts and 30M+ companies (vendor claim).

Plans run Free at $0, Basic at $49 per seat a month billed annually ($65 monthly), Professional at $79 annually ($99 monthly), and Organization at $119 annually with a 3-seat minimum. A credit buys an email for 1 and a phone number for 8, with no rollover. For comparisons see the best Apollo alternatives.

Best for: small SDR teams that want tech-based filters, contacts and sequencing together. Not ideal for: analysts who need deep technology coverage beyond the web.

8. Similarweb Sales Intelligence: tech data with traffic signals

SimilarTech is no longer sold on its own. Its site now reads "A Similarweb Company", and the paid path is Similarweb Sales Intelligence. Similarweb says the product blends contributory network signals, direct site measurement, panel analytics and public sources, and lets you filter by technographic data and track technology changes. It doesn't state a technology count, and pricing is on request.

Best for: teams that want website traffic and technology data in one place. Not ideal for: anyone wanting a standalone, priced technology database.

9. Enlyft: install-base modeling for software and cloud sellers

Enlyft states it tracks 24,000+ technologies across 45M+ companies and 50+ first-party signals per account (vendor claims), modeled in-house in what it calls an Intelligence Graph. It powers channel tools such as Microsoft partner programs, according to its site. Pricing isn't published; the call to action is a demo. It doesn't explain which sources feed the signals, so ask for them during evaluation.

Best for: cloud, security and software vendors and channel teams that sell against an installed product. Not ideal for: buyers who need a published price or self-serve trial.

10. TheirStack: tech stack from job postings, with public credit pricing

TheirStack is the most transparent newer entrant on price. App company credits are one-time packs: 1,000 credits for $109, up to 200,000 for $999. One credit unlocks a company's jobs, tech stack and firmographics, viewable for 90 days. API plans run monthly from $49 for 1,500 credits to $5,500 for 5,000,000, with a 10% discount versus buying packs. Unused credits roll over for 12 months. Annual prices aren't listed.

Its datasets include 225M job records and 51M technographics records (vendor claims). Because detection leans on job postings, it shows what companies are hiring for, which is a stronger buying signal than a script tag but a weaker proof of production use.

Best for: technical founders, growth engineers and data teams who want API access. Not ideal for: teams that need every installed tool, including those no job post mentions.

11. W3Techs: the transparent source for market-share research

W3Techs isn't a lead list. It publishes technology usage statistics and says it measures technologies used on "the relevant web", excluding parked and spam sites. It revisits a site about once a month, updates reports daily and generates larger market reports monthly. The page doesn't list subscription prices, so confirm any paid access with the vendor.

Best for: analysts and marketers who need market-share trends (for example, which CMS is growing). Not ideal for: anyone who needs a list of accounts or contacts.

12. WhatRuns: a free extension for one-off lookups

WhatRuns calls itself a free browser extension that identifies technologies on any website and claims 450k+ active users, with 50 to 100 new web apps added daily (vendor claims). The page lists no paid plans and doesn't describe how detection works.

Best for: developers and marketers checking a competitor's site. Not ideal for: building lists or exporting data.

13. Datanyze: now a contact-reveal extension

Datanyze used to be a technographic prospecting name. Today its product is a Chrome extension that reveals contacts. ZoomInfo acquired it in 2018. The pricing page shows Nyze Pro 1 at $29/mo billed monthly (80 credits) or $21/mo billed yearly, and Nyze Pro 2 at $55/mo monthly (160 credits) or $39/mo yearly, per user. Nyze Lite is a 90-day trial at 10 credits a month, not a permanent free tier. One credit is one contact reveal.

Best for: individual sellers who want cheap contact reveals while browsing. Not ideal for: anyone looking for a technographic list builder.

Accuracy and compliance: what to check before you buy

Technology data goes stale in a few ways: a company switches vendor, a crawl misses a subdomain, or a record points to a contact who left. Median employer tenure is 4.1 years, so assume the people attached to old records move on. Salesforce's report also notes 46% of sales pros with agents say data quality issues hurt their sales.

On compliance, the technology fact about a company is business data, but contacts attached to it are personal data. The French regulator fined Kaspr EUR 240,000 for collecting LinkedIn members' contact details, a reminder that scraping personal contacts is a legal risk even when the intent is B2B. For calls, the FTC says Do Not Call civil penalties reach $53,088 per violation but the registry rule does not apply to business-to-business calls. In the UK, the ICO fined a firm £160,000 for calls to TPS and CTPS numbers, including businesses. In Southeast Asia, check PDPA obligations in each country you sell into. This isn't legal advice; have counsel review your outreach.

How to Choose: Decision Framework

What to Do Next

Pick one use case and run a two-week test. If you're a developer or marketer, install Wappalyzer and WhatRuns and compare results on five sites you know well. If you're building sales lists, choose one technology your best customers run, pull the same list from two tools (for example BuiltWith and Apollo), and check overlap and contact bounce rates before committing to an annual plan.
