I like Serverless on aws. It's super cheap (free tier), and even the database in RDS has a free version for Postgres. Front end I like to deploy using Next.js and Vercel or Netlify. I haven't had a problem scaling because its all lambda so it scales nicely and is all self contained for functions. I've used DynamoDB with is even simpler but if you think you'd ever want something relational or more familiar I would definitely go with Postgres RDS
