Railway is the most hassle-free PaaS for OPC to deploy complete backends (including databases) — one-click add PostgreSQL/Redis, auto-injected environment variables, git push deploy. Starts at $5/month, more modern than Heroku (which no longer prioritizes the solo-dev market) and Render. Best suited for OPC products needing traditional backends (Express/FastAPI/Go). If your product is pure frontend/edge compute, Vercel + Supabase may be better.
