User-Agent Parser
Identify common browser, operating-system, device and bot signals locally.
Interpret common User-Agent signals
User-Agent strings are historical compatibility identifiers and often contain misleading tokens. This parser reports recognizable patterns rather than guaranteed device identity.
Client hints and feature detection are generally better for adapting website behavior.
How to use the User-Agent Parser
- Enter or upload the information requested by the tool.
- Run the tool and review the result for accuracy.
- Copy or download the result, then test it in its intended context.
Practical example
Use a small known sample first so you can compare the output before processing a larger value.
What this tool cannot guarantee
The result reflects the supplied input and browser implementation; project-specific syntax and runtime behavior still require testing.
