If you are a maker or founder then where do you host your saas?
1. AWS 2. DigitalOcean 3. Google Cloud or any other
I used Linode and Heroku. But started to build with Next.js lately so I'd probably go with Vercel.
The railway.app is quite a good alternative. It is comparatively way cheaper, but an excellent solution. From the options you provided, AWS is good.
