Interactive intelligence tool

Run the check, then ship the workflow

Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.

1
Start with the live form

Enter a domain, URL, IP, email, or record and get a focused result without setup.

2
Review decision-ready signals

Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.

3
Automate the winning workflow

Use the request and response examples to turn a one-off check into an API call or recipe.

What this tool helps you decide

Each page is shaped around a practical operational question, not just a raw lookup.

Signal

See the current DNS, registration, security, pricing, or reputation evidence.

Context

Compare the result with related checks so the next move is easier to trust.

Action

Copy examples, open linked tools, or move into API documentation when you need scale.

Trust signals before you integrate

Transparent docs, authenticated requests, and visible reliability details make it easier to evaluate DomScan before you ship.

Service status API artifacts

OpenAPI, Swagger, Postman, CLI, SDK, and MCP links are one click away.

API keys Protected access

Authenticated endpoints use API keys with clear credit costs before you call them.

Free allowance Sign Up for Free

Start with 10,000 monthly credits and upgrade only when usage grows.

Active Example Request

Start from the curl and HTTP samples, then map the parameters into your application code.

Key Features

Technology Stack Detector

The verified catalog covers more than 500 technologies across 80+ categories, including CMS platforms, frameworks, analytics, session replay, tag management, advertising, CDNs, hosting, payments, marketing, developer tools, and security services. Results depend on public signals, so this is not a claim that every technology can always be detected.

Detected Technologies

Confidence is signal-specific. Results include a numeric score, sanitized evidence, caveats, and complete or partial analysis status. Technologies that hide or rewrite public signals may not be detected.

Detect Technologies

Use GET /v1/tech?domain=example.com for one scan, POST /v1/tech/bulk for up to 10 ordered fast scans, or POST /v1/tech/jobs for up to 100 fast, rendered, or deep scans with polling and paginated results. Billing and eligible refunds are settled per target.

Frequently Asked Questions

What technologies can this tool detect?

The verified catalog covers more than 500 technologies across 80+ categories, including CMS platforms, frameworks, analytics, session replay, tag management, advertising, CDNs, hosting, payments, marketing, developer tools, and security services. Results depend on public signals, so this is not a claim that every technology can always be detected.

How accurate is the detection?

Confidence is signal-specific. Results include a numeric score, sanitized evidence, caveats, and complete or partial analysis status. Technologies that hide or rewrite public signals may not be detected.

Why would I want to know a website's tech stack?

Common use cases include: competitive analysis to understand technology choices, security research to identify vulnerable software versions, sales prospecting to find companies using specific tools, technical due diligence for acquisitions, and learning how successful websites are built.

Can I detect technologies for competitor websites?

Yes, our tool only analyzes publicly visible information from HTTP responses - the same data any visitor sees. This is useful for competitive intelligence, understanding market trends, and identifying technology adoption patterns in your industry. Combine with our domain health check for comprehensive competitive analysis.

Is there an API for bulk tech detection?

Use GET /v1/tech?domain=example.com for one scan, POST /v1/tech/bulk for up to 10 ordered fast scans, or POST /v1/tech/jobs for up to 100 fast, rendered, or deep scans with polling and paginated results. Billing and eligible refunds are settled per target.
