What is BrowserDNA?
BrowserDNA is a free browser diagnostics website. It helps you inspect browser fingerprint signals, user agent details, viewport size, screen data, cookies, storage APIs, feature support, permissions, network hints, client hints, media device visibility, and security context status.
Who is BrowserDNA for?
BrowserDNA is useful for developers, QA testers, technical support teams, privacy-aware users, website owners, and anyone who wants to understand what their browser exposes to websites.
Does BrowserDNA show my real browser fingerprint?
It shows a practical browser fingerprint estimate based on signals available to JavaScript, such as user agent, language, timezone, screen size, canvas, audio, and WebGL data. It is not a universal fingerprint used by every website, but it helps explain why a browser can look recognizable.
Do the tools run locally?
Most checks run directly in your browser using normal web APIs. Some features, such as the AI Privacy Report, send the displayed diagnostic rows to a server endpoint so Azure OpenAI can generate an explanation.
What does Analyze with AI do?
The AI report reviews the tool results and returns a privacy or compatibility summary, a score, notable signals, recommendations, and developer notes. It is an educational explanation and should not be treated as a security audit.
Why do results differ between browsers?
Browsers expose different APIs and privacy protections. Results can also change in private windows, strict tracking protection, VPNs, corporate devices, mobile browsers, extensions, and embedded webviews.
Can BrowserDNA detect bots?
BrowserDNA can reveal signals that may be useful when reviewing automation, unusual browser environments, or webviews. It does not make a guaranteed bot decision by itself.
Does BrowserDNA store my results?
We may log technical request data for rate limiting, troubleshooting, security, and service reliability. Raw browser tool checks are displayed in your browser. AI analysis requests may be logged with limited metadata such as action, status, tool slug, and row count.
Do I need to install anything?
No. BrowserDNA tools run in the browser. You do not need an extension, account, or download.
Why are some fields unavailable?
Browsers intentionally limit some APIs for privacy or security. A field may also be unavailable because the page is not in a secure context, the browser does not support the API, or permission has not been granted.
Is BrowserDNA free?
Yes. The public tools are free to use. We may apply fair-use limits to protect the service from automated abuse or excessive AI requests.
Can I use BrowserDNA for website support?
Yes. BrowserDNA is useful when a support team needs to understand a visitor browser environment. You can copy tool results and share them with a developer or support agent.
How do I report an issue?
Use the Contact Us page and include the tool URL, browser name, operating system, and a short explanation of what looked wrong.
