Building a SaaS with Next.js + PostgreSQL. Need to deploy soon but overwhelmed by all the options.

Vercel seems obvious for Next.js but their database offerings seem pricey. Netlify has been around forever. Railway looks promising but not sure about scaling.

Requirements:
– Next.js frontend
– Node.js API routes
– PostgreSQL database
– Maybe Redis for caching
– Need to scale eventually

What’s the best combo in terms of DX + cost + reliability? 🤔
