The $0/Month AI Tech Stack for Bootstrappers — 2026 Edition
You don't need funding to launch. You don't need AWS credits. You don't need to spend a cent on infrastructure until you have paying customers.
Here's the stack I use to ship MVPs for $0/month. Every tool on this list has a free tier generous enough to get you from idea to revenue. When you hit the limits, you'll be making money — that's when you upgrade.
The Core Stack
| Need | Tool | What the Free Tier Gets You |
|---|---|---|
| Frontend hosting | Vercel or Netlify | Unlimited sites, generous bandwidth, automatic HTTPS, CI/CD from Git. Both handle moderate traffic before you need to pay. |
| Backend + database | Supabase | Postgres database, auth, storage, and real-time subscriptions. Free tier covers an MVP and then some. The database alone is worth the switch from Firebase. |
| Authentication | Supabase Auth or Clerk | Both offer generous free tiers with social login, magic links, and user management. Supabase Auth is built-in if you're already on their database. Clerk has a nicer UI. |
| Payments | Stripe | No monthly fee. You pay per transaction (2.9% + $0.30). Stripe's checkout and billing portal handle the heavy lifting. |
| Analytics | PostHog or Plausible | PostHog is more powerful (session replays, feature flags). Plausible is lighter and privacy-first. Both have usable free tiers. |
| Email sending | Resend | Free daily sending allowance covers transactional emails, welcome sequences, and password resets. Clean API, works with React Email. |
| Error tracking | Sentry | Enough free events to catch bugs before your customers do. Set it and forget it until something breaks. |
AI Tools for Development
| Need | Tool | Notes |
|---|---|---|
| AI-powered IDE | Cursor | The best AI coding experience right now. Free tier is usable; Pro is worth it if you code daily. Agent mode, inline editing, and multi-file context. |
| Alternative IDE | Windsurf | Competitive with Cursor. Different UX philosophy — some people prefer it. Try both. |
| UI generation | v0 by Vercel | Describe a UI and get production-ready React/Tailwind code. Good for rapid prototyping and component scaffolding. |
| Full-stack builder | Bolt or Lovable | Describe an app and get a full-stack deployment. Less control than Cursor, but faster for simple MVPs. |
| AI chat | Claude or ChatGPT | Free tiers work for most tasks. Upgrade when you need longer context, faster responses, or better reasoning on complex problems. |
Design, Content & Marketing
| Need | Tool | Notes |
|---|---|---|
| UI design | Figma | Free tier covers solo design work. Good for wireframes, mockups, and handing off designs to AI coding tools. |
| Diagrams | Excalidraw | Quick architecture sketches, flowcharts, whiteboarding. Free and open source. |
| Social graphics | Canva | Free tier handles quick graphics for social media, Product Hunt assets, and blog images. |
| Newsletter | Loops or Buttondown | Both have free tiers for small lists. Loops is more polished. Buttondown is simpler and writer-focused. |
| Background jobs | QStash or Inngest | For scheduled tasks, webhook processing, and async workflows. Free tiers cover most MVP needs. |
What's Worth Actually Paying For
The free tiers above will get you to launch. Once you have paying customers, here's what's worth upgrading first:
- Cursor Pro — Faster AI coding with better context pays for itself in hours saved.
- Claude Pro or ChatGPT Plus — Better reasoning on complex business and coding problems.
- Supabase — You'll hit the free tier when you have real users. That's a good problem.
- Domain name — $10–15/year. A .vercel.app subdomain works for an MVP, but a real domain builds trust.
Everything else can stay on free tiers until the costs become trivial relative to your revenue. Don't pre-optimize infrastructure for scale you don't have.
One Warning About Free Tiers
Tool landscapes change fast. Limits get adjusted. Pricing models shift. Before committing to any tool, check their current pricing page. The specific free tier numbers in this article will age — the strategy won't.
The principle is what matters: you can ship a real, production-ready SaaS product for $0/month in 2026. The tools are better than they've ever been. The only bottleneck is execution.
