Guide to Filling the User Agent Field
A user agent (UA) is a string that websites use to identify your browser, operating system, and sometimes device type. By customizing or selecting a user agent, you can influence how servers perceive your browser’s capabilities and environment.
Where to Get a User Agent
1. Copy From a Real Browser:
Open any standard browser on your system (e.g., Chrome or Firefox). Visit a site like WhatIsMyBrowser.com or UserAgentString.com to see your current user agent. Copy that string and paste it into the “Custom User-Agent” field in Instanciar.
2. Use a Known Reference:
Many websites list collections of common user agents for different platforms (Windows, macOS, Linux, Android, iOS). Copy one from those lists and paste it into the field.
3. Build Your Own:
If you want a more customized approach, you can modify parts of an existing user agent or create one from scratch. Note that extremely unusual user agents can sometimes be flagged by websites.
Examples of Common User Agents
Below are five sample user agent strings that you can use or adapt:
Mozilla/5.0 (Windows NT 10.0; Win64; x64)
AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/112.0.5615.137 Safari/537.36
Mozilla/5.0 (Macintosh; Intel Mac OS X 12_6_3)
Gecko/20100101 Firefox/113.0
Mozilla/5.0 (iPhone; CPU iPhone OS 16_1 like Mac OS X)
AppleWebKit/605.1.15 (KHTML, like Gecko)
Version/16.0 Mobile/15E148 Safari/604.1
Mozilla/5.0 (Windows NT 10.0; Win64; x64)
AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/112.0.5615.137 Safari/537.36
Edg/112.0.1722.64
Mozilla/5.0 (X11; Linux x86_64)
AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/113.0.5672.63 Safari/537.36
Tips and Best Practices
- Try to match your OS: If you’re on Windows, using a Windows-based user agent often avoids suspicion. If you want to appear as a Mac user, pick one referencing macOS.
- Stay within realistic version numbers: Using a browser version far beyond current releases or referencing an out-of-date OS might raise flags.
- Keep consistency: If you’re adding other identity tweaks (e.g., time zone, language), select a user agent that plausibly matches those settings.
Summary
1. Choose or paste a valid user agent string into the “Custom User-Agent” field.
2. When the “Antidetect” checkbox is enabled, Instanciar will inject this user agent into the browser instance.
3. Changing the user agent helps mask or mimic different browsers and operating systems, but be sure to pick one that aligns with your other identity settings (time zone, language, OS type).
