Why This Stack

I've built and run [SocialMate](https://socialmate.studio) on this stack since early 2026. It handles scheduled posts, AI generation, Stripe payments, and background jobs. Monthly infrastructure cost before revenue: $0.

The Stack

**Next.js (App Router)** — Full-stack framework. Frontend + backend in one codebase. Vercel deploys it in one click. Free and open source.

**Supabase** — Managed Postgres + auth + row-level security + file storage. Free tier: 500MB database, 1GB storage, 50k monthly auth users. Covers your first several hundred users.

**Vercel** — Deployment. Push to GitHub → live in 60 seconds. Free tier: 100GB bandwidth/month.

**Stripe** — Payments. No monthly fee. 2.9% + 30¢ per transaction.

**Inngest** — Background jobs. Free tier: 50k function runs/month.

**Resend** — Transactional email. Free tier: 3,000 emails/month.

Total Monthly Cost

$0 until you outgrow free tiers. Full setup guide: [Vol. 4 of Gilgamesh's Guides](https://socialmate.studio/guides/vibe-coding-with-ai).
