Multiple Browser Contexts using CDP

[Mor Amrani]

Hello,

Is there a way to create multiple persistent profiles/Browser Contexts using CDP?

Target.createBrowserContext method description indicates that the new browser context is similar to an Incognito one and this is well represented by the code:

Incognito profile when using headless -https://source.chromium.org/chromium/chromium/src/+/main:headless/lib/browser/headless_devtools_manager_delegate.cc;l=89;drc=03d319de4351bb6ad328e34fded98f6c4b62e65a;bpv=1;bpt=1

Off-the-record profile when using headful -
https://source.chromium.org/chromium/chromium/src/+/main:chrome/browser/devtools/devtools_browser_context_manager.cc;l=52;drc=03d319de4351bb6ad328e34fded98f6c4b62e65a;bpv=1;bpt=1

Is there a reason for not using regular profiles?
Is there a plan to support this?

Thanks,

Mor

You can use existing profile folders using --profile-directory (assuming --user-data-dir also points somewhere existing). More: https://github.com/GoogleChrome/chrome-launcher/issues/172#issuecomment-555277231

AFAIK you cannot create/select Chrome profiles over CDP.

Thank you Paul, this is very helpful!

I have managed to use multiple profiles with the same browser process when running headful. However, this doesn't work for me when running headless.

Is it fair to say that the browser must be launched in headful mode in order to use the --profile-directory option?

Hi,

Checking here again as it's been nearly 4 years since this was discussed :)

Are there any plans or a roadmap for natively managing persistent browser contexts over CDP?
Currently, Target.createBrowserContext remains strictly incognito. If we want to manage multiple persistent profiles using CDP, the only way is to spawn separate Chrome instances for every profile via --user-data-dir. This adds significant process overhead. Having a protocol-level way in CDP to dynamically create or load to a persistent profile directory on a single running browser instance would be hugely beneficial.

Hi Mor,

CDP is not a public API. We made decisions on extending it based on requirements of our supported products, not based on public feature requests.

Cheers,

Yang
