This page reads what your browser reports about itself and shows it plainly: browser name and version, operating system, and the full user-agent string sent with every request. It's handy for support tickets and bug reports, and it runs locally — the detection uses information your browser already exposes to any page, so nothing is uploaded.
Frequently asked questions
- Why does the version look generic or rounded?
- Modern browsers deliberately freeze or reduce user-agent detail for privacy, so the reported version can be generic. What's shown is what your browser chooses to disclose, not always the precise build.
- Can I trust user-agent detection for security?
- No. The user-agent is trivially spoofable, so it should never gate authentication or sensitive features. It's fine for display, support, and rough compatibility decisions.
- How do I check this on my phone?
- Just open the page on the phone — it reads whatever browser you're using at that moment, so the mobile browser and OS report themselves exactly.
