How to bring .ipa to the device?

Hi is there a way to upload the ipa file to TestFlight without a mac? Or are there any other possibilities to get the app running on a device without emulator?

Maybe someone else can chime in with a solution but I’m unfortunately not aware of one.

A workaround that some people use is to rent a Mac in the cloud for an hour or two to do the upload.

Some other ideas: - looks kinda sketchy but maybe it will work? I can’t vouch for it.
Mac VPS may be an option too.

Less sketchy alternative is It does not require your Apple ID or Password.
