About this tool

Made for the task at hand.

Extract useful clues from familiar desktop and mobile User-Agent strings. Results are heuristic because clients can omit or spoof these values.

How to use

  1. Paste one complete User-Agent header value.
  2. Review browser, system, engine, and device fields.
  3. Use the spoofing note when interpreting the analysis.
Your work stays yours.
Tool inputs are processed locally in your browser and are never sent to KitVerse servers. Clear the workspace when using a shared device.
Common questions
Is this as complete as a UA database?

No. It is a compact local heuristic parser for common signatures, not an exhaustive device database.

Can a User-Agent be trusted?

Not completely. It is self-reported and can be changed, frozen, or reduced by the client.
