Hey! Thanks for asking. In this case, I used: - Cursor for IDE (Claude 3.7 Sonnet + Gemini 2.5 Pro for code gen) - Rails app with an embedded React frontend (Rails for API routes / React for everything frontend) - Deploy the Rails app to GCP Cloud Run with min_instances=0; use the tiniest GCP Cloud SQL instance for Postgres; and spin up a tiny cheap VM for running background jobs (same Rails app, just run in sidekiq mode instead of Rails mode) DigitalOcean droplets (cheap servers) are a great option for doing it all on a single VM.
