How do you deploy a small business web app (Next.js + Bun API + PostgreSQL) for a client who can't afford much hosting?

built a dealer management system for a tea reseller (basically a billing/accounting app). The tech stack is: Frontend: Next.js 15 (App Router) Backend: Hono framework running on Bun Database: PostgreSQL with Drizzle ORM Auth: Better Auth (session-based, role-based access) About the business: ~400 customers (tea leaf suppliers) 5-10 staff users max Daily data entry (tea collection weights), monthly billing with deductions Database will be tiny — maybe 15 MB/year of pure text data They want it to feel like a desktop app but with data stored safely in the cloud Budget is very tight — ideally free or under $5/month What I've considered: Free tier stack (Vercel + Render + Neon) — $0 but Render free tier sleeps after 15 min, cold starts are annoying VPS (Hetzner/DigitalOcean ~$5/mo) — Hostinger Node.js hosting — doesn't support Bun or PostgreSQL PWA for the "desktop app" feel — seems like the right call My questions: For developers who build apps for small businesses in developing countries — what's your go-to deployment strategy? Is the free tier stack (Vercel + Render + Neon) reliable enough for production? Would you switch from Bun to Node.js just to have more hosting options? The Bun lock-in is becoming a pain. Is there a better approach I'm not seeing? Something between "run it on a local PC" and "pay for a VPS"? How do you handle backups for clients who can't manage their own infrastructure? Any advice appreciated. This is my first time deploying a production app for a real business and I want to get it right — it handles their financial data. submitted by /u/Iamxv [link] [留言]
