The honest answer about "free" AI app building
Quick answer
Completely free AI app building — building something real and hosting it live at zero cost — is technically possible but the free tiers have real limits most guides do not tell you. To build seriously, expect $18/month.
Genuinely free — no time limit
- GitHub — code storage
- Netlify basic hosting
- Supabase basic database
- Claude basic web chat
Free tier — with usage limits
- Lovable — 5 credits/day (1–2 small changes)
- Bolt.new — limited usage
- Base44 — limited credits
- Supabase — 500MB database limit
- Resend — 3,000 emails/month
Requires payment to build seriously
- Claude Code requires Claude Pro at $18/month
- There is no free version of Claude Code
The realistic conclusion: you can explore and prototype with free tools. To build something that runs reliably and handles real users — expect to spend $18–30 per month. Still dramatically cheaper than any alternative.
The genuinely free tools — what each one does
| Tool | What it does | Free tier | When you hit the limit |
|---|---|---|---|
| GitHub | Where your code is stored and backed up. Google Drive for your app. | Unlimited public and private repositories — forever | You will not hit this limit |
| Netlify | Publishes your website or app to the internet and gives it a real URL. | Unlimited sites. 100GB bandwidth/month. Custom domain connection. | 100GB is a lot for a new project. You will not hit this without thousands of visitors. |
| Supabase | The database that stores your users, their data, and anything your app needs to remember. | Two projects. 500MB database. 50,000 monthly active users. | 500MB is more than enough for hundreds of users. Paid is $20/month when you are ready. |
| Resend | Sends emails from your app — welcome emails, notifications, subscriber emails. | 3,000 emails per month. One custom domain. | 3,000 emails = 3,000 users receiving one email each. You will have a real business before you hit this. |
| Claude chat (claude.ai) | The chat version of Claude in your browser. Great for planning. Cannot build files on your computer. | Limited messages per day on the Sonnet model. | This is NOT Claude Code. The free chat version cannot build your app — it can only advise. |
| Bolt.new | AI app builder in the browser. Describe your app. Bolt builds it. No installation needed. | Limited daily usage. Enough to explore and prototype. | Not enough for complex builds. Best use: test what is possible before committing to a paid tool. |
| Lovable | AI app builder in the browser with polished visual output. | 5 credits per day — roughly 1–2 small changes. | Best use: explore the interface and see what it produces before deciding on a paid plan. |
The cheapest realistic path to a live app — step by step
Month 0 — Before spending anything ($0)
- Week 1: Use Bolt.new free tier to prototype your idea. Describe what you want. See what it builds. Test it. Zero cost.
- Week 2: Sign up for GitHub free account. Create your first repository. Get comfortable with saving your work. Zero cost.
- Week 3: Sign up for Netlify free account. Deploy your Bolt prototype to a real URL. Share it with five people who have the problem you are solving. Get feedback. Zero cost.
- Week 4: Decide whether your idea has enough interest to invest $18/month. If two or more of those five people asked how to sign up — it does.
Month 1 — First investment ($18)
- Subscribe to Claude Pro. $18.
- Start the free 21-day Claude Code challenge on this site. Day 1 is installation. By day 7 you have a working homepage. By day 14 you have email capture. By day 21 you have the core feature working.
Month 2 — First live users ($18–38)
Your app is live. Real people are using it. You may hit Supabase limits if you have hundreds of users — move to paid at $20/month. Otherwise — still $18/month.

What you can build at each price point
| Monthly spend | What you can build | Good for |
|---|---|---|
| $0 (free tiers only) | A prototype to test your idea. A simple landing page with waitlist. A basic site with no user accounts or database. | Idea validation before spending anything |
| $18/month (Claude Pro only) | A complete website with multiple pages. Email signup that stores subscribers. Contact forms. A lessons or blog platform. | Getting something real and live |
| $18–40/month (Claude Pro + Supabase) | Everything above plus user accounts, saved data per user, and subscriber management. | Building a real product with real users |
| $40–75/month (full stack) | Everything above plus automated email sequences, multiple subscriber segments, and higher database capacity. | Building a business with hundreds of users |
You can go from zero to a real live app for $18. You can build a real business for $40–75/month. Both are extraordinary value compared to any alternative.
