Frequently Asked Questions

What is Platform Checker?

Platform Checker is a free website technology detection tool that analyzes any publicly accessible website and identifies the technologies powering it, including JavaScript frameworks, CMS platforms, analytics tools, CSS frameworks, hosting providers, and more.

How does technology detection work?

We analyze the website's HTML source code, JavaScript files, meta tags, and HTTP response headers using pattern matching. Each technology has unique signatures that we detect through these different channels.

Is Platform Checker free to use?

Yes, Platform Checker is completely free. Simply enter a URL and get instant results about the technologies used on that website.

How accurate are the results?

Each match includes its structural evidence and a confidence label. Complete results can be reused for up to 24 hours; refresh collects new evidence. Partial coverage is clearly labeled. Controlled regression tests do not establish a real-world accuracy percentage.
