Unagent

See how your site behaves in various browsers by tweaking the user agent.

NOTE: Websites may still use fingerprinting techniques to determine what browser you are using.

The user agent tells a website what browser (including the version) you are currently using. By detecting the user agent, websites can change their behavior appropriately (such as by disabling features where not supported).

Features
- Choose from a set of preset user agents
- Use a preset as a global user agent, or paste your own user agent
- Set site-specific user agents to see how a specific site behaves with a specific user agent
- Add your own presets

Unagent does not collect any data, and only rewrites the User-Agent header where necessary.
