Laravel

ASP .NET Core, Ruby on Rails, Django, .... the list goes on and on... The ones that don't usually someone built a package that lets it happen.

I remember Laravel with Socialite [0]. Laravel is what I usually reach for Web SaaS MVP. You only need a VPS and a managed database for testing out the market and can scale a lot without increasing expenses that much..
