I wish there was a way to do this without being locked in with Google as the backend.

Chromebooks are locked to using Google for authentication, but you don't have to use most Google services once logge din.

Now you can even use an alternate Android or Linux browser instead of Chrome.

you can even set the machine up to use guest then just use the web services you want (or even your own) and each session is ephemeral if that's what you want.
