Where can I find a list of all available ChromeOption arguments?

Question

I am a big advocate for reading the manual. But in this case, despite searching online for some time I cannot find a manual explaining all of the available ChromeOptions arguments. Somewhere there must be a listing of all of the string arguments and what they mean.

For example, here are some that I found by stumbling through examples:

var options = new ChromeOptions();
options.AddArgument("incognito");
options.AddArguments("test-type");

Can someone please direct me to a listing? I am using C# 4.6, Selenium 2.45.

List of common switches :
/master/chrome/common/chrome_switches.cc

List of headless switches :
/master/headless/app/headless_shell_switches.cc

To search other switches :
https://source.chromium.org/search?q=file:switches.cc&ss=chromium%2Fchromium%2Fsrc

List of preferences:

This is the one I use: http://peter.sh/experiments/chromium-command-line-switches/

var options = new ChromeOptions();
options.AddArgument("--start-maximized");
options.AddArgument("--ignore-certificate-errors");
options.AddArgument("--disable-popup-blocking");
options.AddArgument("--incognito");

and so forth :)

This is a great resource, but Florent's answer is from the official source. Thank you – Orchard

Actually not all switches that appear in this non-official resource are listed in the official website. For example there is no mentioning of --headless switch in the official list. – Iceberg

+1 This list has significantly more options, more details, and is much easier to read. Even the chrome man page says not all options are listed/official so a resource like this is much more useful. The list also auto updates. – Approximation

Is there a similar list for the Firefox and Internet Explorer drivers? I'm having no luck digging those up. – Virgilio

This should've been included in official docs. Thanks – Crean

Thank you, this led me to try --start-minimized using Edge Chromium 105 which works, finally I can launch a window that is at least somewhat hidden. Now how to close it automatically. – Unthread

Here is an answer about how to use the ChromeOptions used:

ChromeOptions options = new ChromeOptions();
options.addArguments("test-type");
options.addArguments("start-maximized");
options.addArguments("--window-size=1920,1080");
options.addArguments("--enable-precise-memory-info");
options.addArguments("--disable-popup-blocking");
options.addArguments("--disable-default-apps");
options.addArguments("test-type=browser");

why some arguments are with -- (2 dashes) at the beginning but some without? – Conative

Answer 4

I believe this should be like this:

1. Try to eliminate the "--"
2. options > option
3. Capitalize "A" in "Add"
4. Arguments > Argument

    ChromeOptions option = new ChromeOptions();
    option.AddArgument("test-type");
    option.AddArgument("start-maximized");
    option.AddArgument("window-size=1920,1080");
    option.AddArgument("enable-precise-memory-info");
    option.AddArgument("disable-popup-blocking");
    option.AddArgument("disable-default-apps");
    option.AddArgument("test-type=browser");
