User-Agent Parser breaks a dense UA string into readable hints about browser family, operating system, and device class when a support ticket only includes the raw header.
Paste the User-Agent value, run parse, and read the structured hints. It is a starting point for reproduction, not a perfect fingerprint of a specific person.
Modern browsers reduce UA detail on purpose; expect coarse results compared with older verbose strings.
What User-Agent Parser does
Translate raw user-agent text into human-readable hints.
- Input for raw UA strings
- Parsed browser and OS oriented hints
- Device class cues when detectable
- Hint text under the form
- Local parsing of pasted strings
Who User-Agent Parser is for
- Support agents reproducing mobile-only bugs
- Analysts interpreting odd analytics UA buckets
- QA verifying that test devices report expected strings
- Developers debugging middleware that branches on UA
How to use User-Agent Parser
1. Open User-Agent Parser on beeforge.dev.
2. Paste the User-Agent header value into the input.
3. Run the parse action.
4. Use the hints to choose an emulator or ask the reporter clarifying questions.
Features
- Turns opaque UA text into labeled hints
- Helpful beside raw header parsing
- No need to install a UA library locally for a one-off
- Client-side processing of pasted strings
- Acknowledges reduced UA precision in modern browsers
Examples
- Parse a UA from a crash report to see if it is iOS Safari vs Chrome.
- Explain to a stakeholder why two 'Chrome' rows differ by OS.
- Check a bot-like UA before deciding to rate-limit a scraper.
Tips and limits
- UA spoofing is trivial; do not treat results as strong identity.
- Client Hints and reduced UAs may omit version detail you expect.
- Combine with logs of Accept-Language and viewport when reproducing UI bugs.
- Bots often declare themselves clearly; humans can still spoof those tokens.

FAQ
Is parsing perfect?
No. UA strings are messy and sometimes reduced. Treat output as hints.
Where is the string processed?
In your browser. The UA text is not sent to BeeForge for parsing.
Can it detect bots reliably?
Some bots self-identify. Others impersonate browsers. Use multiple signals.
Why is version missing?
Privacy-reduced user agents intentionally freeze or hide versions.
Does it use Client Hints?
This tool parses the classic User-Agent string you paste, not live Client Hints from your visit.
