A short companion for User Agent Parser: when it is useful, what it expects, and what to check before using the result.
What it does
Break a user-agent string into browser, version, engine and operating system, and explain what each part is for.
Use the tool

Input and output
- Input: text.
- Output: text.
- Category: Web.
Privacy and processing
Processing happens locally in your browser. This tool does not upload the input to ilham.dev.
Questions
Why is the browser detected wrongly?
Because user-agent strings lie, deliberately. Every browser claims to be Mozilla, and some reduce or freeze the rest of the string. Treat any detection as a hint, and feature-detect instead whenever you can.
