Detect browser name, version, OS, user agent, installed plugins, and supported Web APIs in your current browser.
Browser Info Detector examines the browser session in which its page is open. It reports the apparent browser and version, operating system, user-agent string, browser-exposed plugins, and the Web APIs available in that context. There is no text input because the current browser is the subject of the inspection. The main surprise is that browser and OS labels are inferred from self-reported data. Privacy protections, compatibility tokens, or user-agent overrides can make those labels incomplete or misleading.
The detector reads browser-exposed identification data and presents both the raw user-agent string and interpreted browser, version, and operating-system labels. These fields describe what the current session reports, not a verified software installation. A browser may reduce version details, imitate another browser for compatibility, or expose different information after a user-agent override.
The plugin section reflects only plugin information the browser permits web pages to inspect. The Web API section records whether selected browser interfaces are exposed in the current page context. A positive result indicates detectable availability, but it does not prove that permission will be granted, suitable hardware exists, or every operation in that API will succeed.
No. It can summarize information exposed by the current browser session, including its user agent and detectable capabilities. That information may suggest a browser family, version, and operating system, but it is not a reliable device identifier. Different devices can report similar values, and one device can report different values after privacy settings or overrides change.
Browsers no longer expose a general inventory of installed extensions or legacy plugins to ordinary web pages. The reported list is limited to entries available through the browser's plugin-facing web interface, which may be empty or contain standardized PDF viewer entries. An empty result therefore means no plugin entries were exposed, not necessarily that nothing is installed.
