What Is My Everything

23 free browser tools that instantly reveal your IP address, ISP, browser, timezone, speed, location, and more — no registration. See our Privacy Policy for ads and analytics.

All Tools

Network10

Instantly see your public IPv4 and/or IPv6 address with ISP, city, and country details.

See which Internet Service Provider (ISP) or organization is associated with your public IP and connection.

Look up public DNS A and AAAA records using Cloudflare DNS over HTTPS, with honest labeling about resolvers.

Ping & Latency Test

Measure HTTPS round-trip time from your browser to this site—a practical “ping” when ICMP is not available in the web sandbox.

What Is My Network Type

Detect whether you are on Wi-Fi, cellular, or ethernet, with effective speed class and estimated bandwidth from the Network Information API.

Internet Speed Test

Test your download and upload speeds with a fast, accurate in-browser speed test.

ISP Throttling Test

Check whether your ISP is slowing video: compares download speed to Netflix’s servers against generic servers and says whether it looks like shaping or congestion.

Email Header Analyzer

Trace an email's delivery path and check SPF, DKIM and DMARC. Headers are parsed in your browser, never uploaded.

Connection Report

Run every network, browser and device check at once and copy one plain-text summary into a support ticket.

Find out whether your ISP puts you behind carrier-grade NAT — the usual reason a forwarded port stays unreachable.

Security & Privacy4

What Is My VPN / Am I Leaking?

Compare your HTTP-visible public IP with WebRTC ICE reflexive addresses to spot possible IP leaks, plus plain-language DNS leak context.

What Is My Cookie / Tracking Status

See whether first-party cookies and web storage work, what DNT/GPC report, and visible cookie surface—plus honest limits for HttpOnly and cross-site tracking.

Open Port Checker

Check which TCP ports are open, closed, or filtered on your public IP address — no software needed.

Password Breach Check

Check whether a password appears in known data breaches. It is hashed in your browser and never sent anywhere.

Browser & Device7

What Is My Browser

Detect your browser name, version, engine, and operating system in one click.

What Is My User Agent

See the full user agent string your browser sends to websites and servers.

What Is My Screen Resolution

Check your screen resolution, color depth, pixel ratio, and viewport size.

What Is My WebGL / GPU

Detect your GPU renderer, vendor, WebGL version, and key graphics capabilities directly from your browser — no plugins required.

What Is My Refresh Rate

Measure your monitor’s real refresh rate (Hz) live in the browser — see whether 60, 120, 144 or 240 Hz is actually active, with frame-time stability.

Invisible Character Detector

Find and remove zero-width characters, unusual spaces and hidden Unicode in any text. Checked in your browser.

Video File Inspector

Read a video file's codec, resolution, duration and bitrate without uploading it. The file never leaves your browser.

What Is My Location

Discover your approximate location based on your IP address including city and country.

What Is My Timezone

Find your current timezone, UTC offset, and local time with DST status.
