Install Compare

The User-Agent Switcher for Chrome extension enables users to effortlessly switch between different user-agent strings. Ideal for web developers testing site compatibility across devices, this tool allows you to mimic various browsers and platforms, including outdated ones like Netscape 4. You can also configure specific URLs to always use a particular user-agent for consistent testing.

Please note, this extension does not enhance online privacy and may impact browsing performance due to data interception and modification. If sites behave unexpectedly after switching to a mobile user-agent, restoring to Chrome's default user-agent and clearing cookies may be necessary. This extension is a valuable tool for developers and testers aiming to simulate various browsing environments easily within Chrome.

User reviews

Multiple users report that the extension is outdated and does not work properly on recent Chrome versions. Common complaints include inability to change the operating system in the user-agent, lack of support for modern headers, and outdated user-agent profiles. Some users experience bugs or very limited functionality with only preset user-agents available. While a few users find it works for basic spoofing, overall it is considered obsolete with better alternatives available.

Pros

Works for some users without issues.
Has pre-installed user-agent profiles available.
Simple to use for basic user-agent spoofing.

Cons

Does not allow users to change the operating system in the user-agent string.
Does not support latest Chrome versions or updated "Client Hints" headers like "sec-ch-ua", leading to ineffective spoofing.
Has very outdated browser profiles and user-agent lists.
Importing custom user-agent lists (e.g., JSON files) does not work properly.
Does not allow users to add or edit custom user-agents beyond the presets.
