Search Domains by Technology: Find Websites by Tech Stack

Search domains by technology lets you choose a detected web technology and review websites associated with it. Each result can include the domain, detection URL, company, industry, and location. Use the free lookup for market research or prospecting, then verify important matches because technology signals can change or be incomplete.

How does searching domains by technology work?

The embedded checker lets you choose one detected technology, then displays the websites associated with it. The visible table can include domain, detection URL, company, industry, and location, with up to 50 results per search.

  1. 01

    Choose a technology

    Search the picker for a specific platform, framework, analytics tool, ecommerce product, or another labeled technology.

  2. 02

    Load matching websites

    Select the technology to open a result table of domains where that signal was detected.

  3. 03

    Review and verify matches

    Sort the available fields, open the detection URL, and verify important matches before research, segmentation, or outreach.

What does the technology search result show?

The result is a research table rather than proof of a current vendor relationship. Each row can expose the following technology and company context.

Domain

The website hostname associated with the selected technology signal.

Detection URL

The page URL connected to the observed technology detection.

Company

The available organization name associated with the matched domain.

Industry

An available business classification that can support broad segmentation.

Location

Available geographic context for the company attached to the domain.

Technology category

The picker labels technologies with categories such as CMS, CRM, or web framework.

What does our lead engineer think?

James BennettReviewed byJames Bennett · Lead Engineer at WebSearchAPI.ai
I use technology search to build a focused list of websites worth checking, not as proof that every company still uses a product today. Public technology signals can disappear, move to another page, or remain visible after a migration. Open the detection URL and verify the match before you base outreach, market sizing, or competitive claims on it.

How should you research websites by technology?

James Bennett · Lead Engineer at WebSearchAPI.ai
  1. Start with an exact product name

    Search for a specific technology such as WordPress or shadcn/ui before expanding to broader product families or categories.

  2. Use the category as context

    A category explains the role of the selected technology, but it does not mean every product in that category is interchangeable.

  3. Open the detection URL

    Check the page tied to the signal. A homepage, checkout, careers page, and documentation site can reveal different parts of a stack.

  4. Verify a sample before outreach

    Review several matches manually before building a campaign or drawing conclusions about an entire market.

  5. Record when you checked

    Technology stacks change. Add a checked date to notes or exports so later decisions are not based on undated observations.

  1. What does searching domains by technology actually show?

    This tool starts with a named web technology and returns domains associated with that signal. It reverses the usual website technology lookup: instead of asking what one website uses, you ask which websites are linked to one selected technology.

    A match is a research lead, not a contractual or current-usage guarantee. The result tells you where to investigate next by exposing the domain, the detection URL, and any available company context.

  2. Which technology categories are useful for research?

    The picker groups products into categories that describe their likely role on a website. CMS, ecommerce platform, analytics, CRM, web framework, security, and marketing categories can each support a different research question.

    Choose the product first and use its category to understand the signal. A category is helpful context, but it should not be used to claim that all products in that group have the same features, buyers, or implementation pattern.

    • Use CMS and ecommerce platforms for migration or implementation research.
    • Use analytics and marketing tools for integration and operations research.
    • Use frameworks and UI libraries for developer-focused market research.
    • Use security and identity products only as an initial signal, not a security assessment.
  3. Why can technology detections be incomplete or stale?

    Technology detection relies on observable website signals. A product can load only after consent, appear on a private page, run behind a proxy, or leave an old script behind after migration. Those conditions can create missing, partial, or outdated observations.

    A missing domain does not prove that the technology is absent, and a visible match does not prove that it is active across the whole company. Open the detection URL and check the current page before using the result in a consequential decision.

  4. How does technology search fit into a real workflow?

    Start with a narrow product and scan the result set for relevant domains. Verify a sample, enrich useful domains with company data, and record why each match belongs in your research list. This sequence separates technology detection from company qualification.

    For outreach, use the signal to make your research more relevant, not to manufacture urgency or imply private knowledge. For market analysis, report the searched technology, checked date, sample size, and known coverage limits.

  5. How should you interpret the five result columns?

    The visible result table combines the detected website with optional company context. Domain and Detection URL explain where the match was observed. Company, Industry, and Location help organize the row when those values are available.

    Treat company context as optional and keep missing values blank. A domain can still be useful for manual research even when an organization, industry, or location is not returned.

Who can use technology-based domain search?

SaaS sales teams

Find websites associated with a complementary or competing product, verify the implementation, and prioritize accounts where the signal supports a relevant conversation.

Agencies and consultants

Research sites using a platform your team implements or migrates, then review the current experience before proposing a service.

Product and market researchers

Build a sample of adopters for a named tool, inspect industry or location patterns, and document the coverage limits behind any conclusion.

What should you know before searching by technology?

Straight answers about result fields, coverage, verification, limits, and responsible use.

  • What is a search domains by technology tool?

    It starts with a named web technology and returns websites associated with that signal. This is the reverse of checking one website for its stack: you choose a technology first, then review matching domains.

  • How do I search for websites using a technology?

    Open the technology picker, type a product name, and choose the matching technology and category. The tool then loads a table of available website matches.

  • What fields can a result include?

    The visible result table includes Domain, Detection URL, Company, Industry, and Location columns. Company context can be missing even when a domain and detection URL are available.

  • Is the technology search free?

    Yes. The embedded search on this page can be used without payment. The page does not promise unlimited volume or an export entitlement.

  • Do I need to create an account?

    No account is required to choose a technology and inspect the available result table on this page.

  • How many websites does one search show?

    The visible tool states that it shows up to 50 results. A technology can return fewer matches, and the page does not claim that the table contains every website using that product.

  • How accurate and current are technology detections?

    A detection is a research signal based on observable website behavior or markup. Products can load conditionally, move behind a proxy, or leave old signals after migration. Verify the detection URL before relying on a match.

  • Why did a technology return few or no results?

    The product name may be different in the picker, its signals may not be publicly observable, or the available dataset may not contain matches. Try the exact product name and review nearby category labels.

  • Can I export or automate the results?

    The free page is designed for interactive research and does not promise an export. Review the current API documentation separately before planning automation, limits, or response fields.

  • Can I use these matches for lead generation?

    Use them as candidates for responsible research. Verify the website and company, respect applicable privacy and outreach rules, and do not claim a company uses a product until you have checked the current detection.
