fastlane boarding process for fabric beta webpage setup

There is fastlane boarding for testflight to distribute builds using webpage

https://github.com/fastlane/boarding

Does it exists for fabric beta testing? what is the config for that , if yes.

Mike from Fabric & Firebase here. I think you're looking for "Share Links" from Beta. After your first build, you can click on Share Links under the Beta tab.

From there, you click on "+ Create New"

and then setup the link with the necessary information. You can also optionally an email domain restriction if you only want testers from your company's domain.

After that, you'll have a static page where folks can sign up to test.
