People always ask: "How do you manage 11 products alone?" The answer is boring but effective: pick the right stack, automate everything, and say no to complexity.
The Core Philosophy
Three rules govern every technology decision I make:
- If it needs a team to maintain, don't use it. Kubernetes? No. Vercel? Yes.
- If it has a generous free tier, start there. Scale when revenue justifies it.
- If it can be automated, never do it manually. Not even once.
The Full Stack Breakdown
Frontend: Next.js + Tailwind + Framer Motion
Every single product runs on Next.js. Why?
- Server Components reduce client-side JavaScript dramatically
- App Router gives me clean, file-based routing
- Vercel deployment is one
git pushaway - ISR/SSG means most pages are pre-rendered and blazing fast
For styling, Tailwind CSS v4 with CSS variables. No CSS-in-JS runtime overhead. Design tokens in one file, consistent across all products.
Framer Motion handles all animations. Scroll reveals, page transitions, hover effects — all declarative, all 60fps.
Backend: Supabase (PostgreSQL + Auth + Storage)
Supabase is the secret weapon of solo developers. One service gives me:
- PostgreSQL database with Row Level Security
- Authentication (Google OAuth, email/password, magic links)
- File storage with CDN
- Real-time subscriptions for live features
- Edge Functions for serverless compute
Cost for all 11 products? Under $25/month total. Try doing that with AWS.
AI Layer: Groq + Gemini + Vercel AI SDK
Every product has some AI component:
- Groq (primary): Llama and Mixtral models at insane speed. Free tier handles most of my volume.
- Google Gemini (fallback): When Groq hits rate limits, Gemini takes over seamlessly.
- Vercel AI SDK: Unified streaming interface. Switch providers with one line of code.
I never use OpenAI for production workloads. The cost doesn't make sense at my scale.
Automation: n8n (Self-Hosted)
This is where the magic happens. A single n8n instance on a $5 DigitalOcean droplet runs 50+ workflows:
- Content repurposing pipelines
- Email nurture sequences
- Payment processing
- Health monitoring
- Social media scheduling
- Lead scoring
- Invoice generation
Payments: Cashfree
For Indian payments, Cashfree is unbeatable:
- UPI, cards, netbanking — all covered
- No monthly fees (pay per transaction)
- Excellent webhook system
- Subscription management built-in
Email: Resend + React Email
Beautiful transactional emails with:
- Resend for delivery (3,000 free emails/month)
- React Email for JSX templates (type-safe, responsive)
- Gmail API for outreach (emails from my own inbox)
Monitoring: Custom + BetterStack
- Custom health check endpoints on every product
- n8n workflow pings all endpoints every 5 minutes
- BetterStack for uptime monitoring and status pages
- Telegram alerts for instant notifications
Hosting: Vercel (Free Tier)
All 11 products deploy to Vercel's free tier:
- Unlimited deployments
- Automatic HTTPS
- Edge network (fast globally)
- Preview deployments on every PR
- Zero configuration
Total hosting cost: $0/month for 11 products. Read that again.
The Monthly Cost Breakdown
| Service | Cost | What It Covers |
|---|---|---|
| Supabase | $25 | All databases + auth + storage |
| DigitalOcean | $5 | n8n automation server |
| Vercel | $0 | All 11 product deployments |
| Resend | $0 | Transactional emails (free tier) |
| Groq | $0 | AI inference (free tier) |
| Domains | ~$12 | Annual cost, amortized |
| Total | ~$31/month |
What I'd Change
Looking back, here's what I'd do differently:
- Start with Supabase from Day 1 — I wasted months with custom auth
- Use n8n earlier — Manual processes killed my productivity in Year 1
- Pick one AI provider — I over-engineered multi-provider fallback too early
- Write more tests — Technical debt compounds faster than you think
The Bottom Line
You don't need a team. You don't need VC funding. You don't need enterprise infrastructure.
You need the right stack, ruthless automation, and the discipline to ship consistently.
