How browser detection works in seconds: The tool reads your navigator.userAgent and navigator.platform strings, checks for browser-specific tokens in a specific order — Edge first, then Opera, Chrome, Firefox, Safari, and IE — and reports the browser name, major version, and operating system. It also captures screen resolution with pixel ratio, language list, CPU cores, memory, and cookie status. Results appear instantly at $0 cost in your browser.
Why browser info matters for USA teams: Austin support agents handling $500 per case tickets need exact browser versions to reproduce bugs and avoid wasting hours chasing phantom issues. Chicago QA teams running $2,000 per sprint compatibility tests must document every tested environment for compliance and audit trails. Miami remote workers reporting $300 per month VPN issues to IT departments need to share accurate OS and browser data. Denver startups debugging $10,000 per month SaaS rendering problems need to know if the user is on Chrome 126 or Safari 17 to reproduce the layout shift.
User-agent parsing and Edge detection: Edge is Chromium-based and includes a Chrome token in its user-agent string. The detector checks for Edge first, then Opera, to avoid misidentifying them as Chrome or Firefox respectively. Some privacy tools and browser extensions strip the Edg token, which may cause Edge to report as Chrome. This is a known limitation of user-agent sniffing across all browsers and cannot be resolved without using feature detection APIs instead.
Hardware and capability reporting: Beyond the browser identity, the tool reports CPU core count via navigator.hardwareConcurrency and approximate device memory when available. Screen resolution includes the device pixel ratio, which matters for retina and HiDPI displays where a 1920x1080 logical resolution may actually be rendered at 3840x2160 pixels. This data helps frontend teams debug responsive layout issues and performance bottlenecks across different device categories.
Privacy, local execution, and practical workflow: All detection runs entirely in your browser. No data is transmitted to any server, stored, or logged. The raw user-agent string never leaves the page, making the tool safe for diagnostic screenshots, support ticket attachments, and bug reports without exposing sensitive browser fingerprint data. Open the tool, copy the details block, and paste it into your support ticket, Jira issue, or GitHub bug report. Use this for $500 per case Austin support triage on 09/01/2026, $2,000 per sprint Chicago QA documentation, $25,000 per client New York ad-tech compatibility checks, or $50 per issue Seattle open-source reporter fingerprints. Close the tab and everything vanishes with no signup required ever.

Frequently Asked Questions
- Why does it say Chrome when I use Edge?
- Edge is Chromium-based and includes a Chrome token. The detector checks Edge first, but some privacy tools strip the Edg token, causing misidentification.
- Is my full user agent shared anywhere?
- No. Detection runs entirely in your browser. The raw string never leaves the page and is never transmitted to any server.
- Can websites detect my exact version?
- Only what your browser sends. Modern browsers are freezing user-agent granularity, so sites increasingly use feature detection instead.
- Why is screen resolution useful?
- Screen size and pixel ratio help debug responsive layout issues. A 1920x1080 display at 1x renders differently from a 1920x1080 Retina display at 2x.
- Does it detect my IP address?
- No. This tool reads navigator properties only. It does not query any network service or reveal your IP address, location, or ISP.
- Can I use this for automated testing?
- Yes. Paste the tool URL into your test harness to capture browser fingerprints. This is useful for documenting test environments in $2,000 per sprint QA cycles.
