User Agent Checker — Your Browser Data, Read Locally

The full userAgent string, hardware hints and privacy flags — copied as JSON with one click.

Quick answer: Read your full user-agent string, platform, languages, privacy flags and hardware hints, then copy the whole report as JSON for bug reports — fully local.

How to use

  1. Read the big userAgent string and the field table — rendered on load, no clicks needed.
  2. Compare device memory, CPU threads and touch points against what your device really has.
  3. Press Copy full report and paste the JSON into a bug report or support ticket.
  4. Toggle Wi-Fi to watch the online-status row change live.

About this tool

Your browser broadcasts a surprising amount of context before you visit any page. This user-agent checker reads it all locally: the full userAgent string in plain sight, the reported platform, your preferred languages, whether cookies and Do Not Track are enabled, plus the hardware hints modern browsers expose — approximate device memory, CPU thread count and maximum touch points — alongside your live online status. One button copies everything as tidy JSON, handy for filing bug reports, QA tickets or support requests where a developer asks which browser you are on. Because the entire report is assembled in your tab from navigator properties, nothing is transmitted and there is no server round-trip: the numbers you see are exactly what JavaScript on any website could see.

FAQ

Why does my UA string not match my actual browser?
Browsers froze the UA string for privacy and now echo historically expected tokens — Firefox deliberately reports like Chrome. Treat it as legacy data.
What is device memory?
An approximate RAM bucket (0.25–8 GB) that Chromium browsers expose; Firefox and Safari return 'not exposed', which this page shows honestly.
Is anything sent to your servers?
No — the report is assembled from navigator properties inside your tab, and Copy merely places JSON on your clipboard.
Why show platform if it is deprecated?
Support templates and bug trackers still ask for it; until it disappears everywhere it remains useful context for diagnosing issues.
What does Do Not Track show?
Whether you enabled the DNT signal (1), disabled it (0), or never set it — most sites ignore it, but it is still worth knowing what you broadcast.
