Every site you visit already knows this much about you.

NetInfo reads your connection the same way a server, a script, or a stranger's link would — then lays out the full picture in one page, in plain language.

Read by this page's script, inside your browser. Nothing is uploaded. Any site can compute the same fingerprint ID from the same values.

What a website can see without asking

None of this needs a login, a download, or your permission. It's handed over automatically the moment a page loads — NetInfo just makes it legible.

IP & ASN

Your public address and the network operator behind it — often naming your ISP, employer, or hosting provider outright.

Location & timezone

City, region, postal code, and timezone, usually accurate to a few kilometres from IP geolocation alone.

Browser & device fingerprint

Screen size, installed fonts, hardware concurrency, and canvas rendering, combined into a signature that can follow you across unrelated sites.

DNS resolver

Which resolver actually answers your lookups — sometimes exposing your real network even while a VPN hides your IP everywhere else.

TLS & HTTP stack

Protocol version and cipher choices that can reveal automation tools, outdated clients, or an unusual proxy in front of you.

WebRTC path

A separate connection channel that can leak your real IP even when every other signal says you're masked.

Bot & fraud signals

A trust score that decides how a site treats you — sometimes flagging normal connections as suspicious for reasons you never see.

Why this is worth five minutes

Privacy used to mean keeping your name off a form. Now it means understanding a dozen quiet signals your device gives away before you've typed anything.

Your connection is a name now

An IP address, an ASN, and a device fingerprint are stable enough to build a profile with — no cookie required, and nothing to delete afterward.

One click connects the dots

Landing on an untrusted or malicious page hands over your fingerprint the instant it loads. That's enough to correlate you with other sessions, or unmask a VPN through a leaked resolver or WebRTC channel before you've clicked anything else.

Awareness is the free defense

Most of this is configuration, not a product you buy: choosing a resolver, disabling WebRTC when you don't need it, checking what a fingerprint reveals. You just need to see it first.

How NetInfo treats your data

A diagnostic tool that watches your connection should be held to a higher bar than the sites it's warning you about.

Local-first by default

iYour approximate geolocation and IP may still be logged by Cloudflare for its own operational metrics, separately from anything NetInfo stores.

Your report is generated and read in your browser. We don't store the exact result unless you choose "Share Report" — and that copy deletes itself after 3 days.

No account, no cookies

Nothing to sign up for and nothing to opt out of later. NetInfo itself sets no tracking cookies — the report just runs and shows you what it finds.

Never sold, never profiled

iThis is written into the Terms you accept on your first visit to the dashboard. The public services it contacts to work (IP checks, DNS test, map tiles, CDNs) follow their own privacy policies.

No ads, no third-party analytics, no visitor profiles. We don't sell personal information, and there's no user database to leak — the only thing we ever store is a report you chose to share.

One report, every angle

NetInfo breaks your connection into sections you can actually read, then lets you jump straight to any of them.

Network Intelligence

ASN, ISP, city, edge PoP, distance to server, and EU-membership status, read straight from the edge.

System Intelligence

Browser, OS, hardware, battery, sensors, permissions, and locale — the fingerprint pieces most sites quietly collect.

Privacy Shield

WebRTC leak check, ad and tracker blocker detection, GPC/DNT signal status, canvas defense, and Tor route detection.

DNS Leak Test

Confirms which resolver is really answering for you, so a VPN's promises can be checked rather than assumed.

Speed Test

Edge-measured throughput and latency, run from the same network path your traffic actually takes.

Global Ping Matrix

Round-trip times to points around the world, so you can see how your connection looks from elsewhere.

Command-line access

Every field available as plain text or JSON — script it, pipe it, or drop it into another tool.

Shareable snapshots

A frozen report link with an expiry, for handing someone a result without giving them a live view of your machine.

Instant search

Press Ctrl+K to jump to any metric in the report — no scrolling through sections you don't need.

Built on infrastructure we didn't have to build

NetInfo runs on Cloudflare's edge and leans on a handful of open, public services rather than reinventing them.

Infrastructure & edge network

Cloudflare Workers, KV storage, and geo-IP data

Map engine & geodata

Leaflet.js, Carto (Dark Matter & Voyager tiles), OpenStreetMap contributors

Diagnostics & public APIs

Cloudflare Speed Test, Bash.ws DNS leak test, ipify, icanhazip, ident.me

Interface

Tailwind CSS, Lucide Icons, Google Fonts (Plus Jakarta Sans)
