Save what you type here, in this browser? Your work would go into this browser's local storage, so a refresh or a trip to another tool does not wipe it. You also get a short list of previous entries under the form, each one restorable with a click. Nothing is ever uploaded, and there is no account.
Being straight about the trade-off: anything kept there can be read by anyone who can use this browser profile, and by any script that later runs on this site. A tool page can hold a private key, a password or a signed token. Saving is convenient; it is not private.
About this tool
A snapshot of the connection and device facts a browser exposes to a page: online state, the Network Information values where they exist, screen and viewport size, pixel ratio, language, CPU threads, memory hint and time zone. It is read locally and never uploaded.
Questions
- Why are some values blank?
- Support varies. The Network Information API, deviceMemory and hardwareConcurrency are not in every browser, and some are rounded or capped for privacy. A dash means the browser did not provide a value, not that it is zero.
- How accurate is the downlink and round-trip time?
- They are estimates the browser derives from recent traffic and are deliberately coarse. They are fine for choosing an image size or deciding whether to prefetch, but not for measuring a connection.
- Does this reveal my IP address or location?
- No. The page only reads values the browser already exposes to JavaScript. It does not call an IP service, does not use geolocation and does not make a network request.
- Why does the time zone matter?
- It is handy when you are debugging a timestamp bug and need to know what the browser thinks local time is. It comes from Intl, so it reflects the system setting rather than anything you typed.
