What Is a Browser Info?

Support engineers and QA testers ask for browser and OS information constantly when triaging issues. The raw user-agent string is brittle but specific; the parsed vendor and version are easier to scan. Other useful values — viewport size, online status, cookie support, JavaScript engine, prefers-reduced-motion — sometimes also matter for bug reproduction.

Product support teams paste the full report into ticket templates so the engineer doesn't have to ask. Web developers verify what a specific browser actually reports versus what they expected. Accessibility engineers check whether prefers-reduced-motion or prefers-color-scheme is set correctly on the user's device. This tool reports everything exposed to JavaScript without requesting any additional permissions.

Nothing is transmitted anywhere — it's a read-only view of what your browser is already telling every site you visit, presented in copyable form.
