Not a company but I’ve been experimenting with different tech stack options over the last 6 months to find a simple tech stack with an independent frontend and an independent backend with a hosted database. The goal is not just to build but also be able to maintain without much complexity and not spend a lot of money on hosting.

Backend: Building a REST/GraphQL API that could be deployed to Cloudflare workers is a no brainer. Super cheap and incredibly fast and when you need to scale it’s still ridiculously cheap. I’d probaby go with REST with swagger + openapi-typescript to generate types on the frontend because honestly GraphQL is a lot of work for one person to maintain.

Frontend: Next.js server render or ISG hosted on Vercel. I'd throw Tailwind on too for rapidly styling your pages.

Database: Prisma with Postgres so it could be typed and works well with other tools. I still haven’t figured where to host Postgres easily. Looking for something like Mongo Atlas where I could grab the connection URL easily and has affordable free/paid plans.
