Build Your Entire Tech Stack for $0 — First-Time Founder Guide (2026)
You don't need money to build a product. You need the right free tools. Here's the complete tech stack that takes you from idea to paying customers for $0.
The Stack
1. Code Editor — Cursor Pro (Free)
Cursor gives students 1 year of Pro access. It's VS Code with AI superpowers — write code faster with GPT-4 and Claude completions. If you're not a student, GitHub Copilot in VS Code is the next best option.
2. Backend — Supabase (Free)
Supabase is your backend in a box: PostgreSQL database, authentication, file storage, edge functions, and real-time subscriptions. The free tier handles most MVPs. Startups get additional credits.
3. Frontend — Next.js + Vercel (Free)
Build with Next.js (React framework), deploy on Vercel. Students get Pro features free — analytics, edge functions, and unlimited deployments.
4. Domain — Free via GitHub Pack
Get a free .me domain through the GitHub Student Developer Pack. Point it to your Vercel deployment. Free SSL via Let's Encrypt.
5. Auth — Supabase Auth (Free)
Built into Supabase. Email/password, OAuth (Google, GitHub), and magic links. No need for Auth0 or Clerk on day one.
6. Payments — Stripe
Stripe charges per transaction (2.9% + 30¢). No monthly fees. Through the GitHub Pack, you get fee waivers on the first $1,000 in revenue.
7. Email — Mailgun (Free Credits)
Mailgun for transactional emails. Password resets, welcome emails, invoices. Student credits cover your first months.
8. Monitoring — Sentry (Free)
Sentry for error tracking. Free for open source projects, free tier for everyone else. Know when something breaks before your users tell you.
9. Analytics — Vercel Analytics (Free)
Built into Vercel Pro. See page views, web vitals, and user geography. No extra setup needed.
10. Team — Slack + Notion + Linear (All Free)
Cost Breakdown
| Layer | Tool | Monthly Cost | |-------|------|-------------| | IDE | Cursor Pro | $0 | | Database + Auth | Supabase | $0 | | Hosting | Vercel Pro | $0 | | Domain | Namecheap via GitHub | $0 | | Payments | Stripe | 2.9% per transaction | | Email | Mailgun | $0 | | Errors | Sentry | $0 | | Analytics | Vercel Analytics | $0 | | Chat | Slack Pro | $0 | | Docs | Notion Plus | $0 | | Tasks | Linear | $0 | | Total | | $0/month |
Your only cost is Stripe's per-transaction fee — which means you only pay when you make money.
When to Upgrade
Stay on free tiers until:
- Database: >500 MB data or >50K monthly active users → Supabase Pro ($25/mo)
- Hosting: >100K pageviews or need team features → Vercel Pro ($20/mo)
- Email: >10K emails/month → Mailgun Flex ($0.80/1000 emails)
Most startups won't hit these limits for 6-12 months.
