What order should you add features in?

Auth first, then data, then payments. Authentication determines who owns what rows, so building your data model before accounts exist means rework. Add login, verify you can store and read per-user data, then layer Stripe on top.

How do you set up authentication?

1. Connect your project to Supabase.
2. Ask Lovable 3 to add email and password sign-up with a protected dashboard route.
3. Test sign-up, login, logout, and a password reset.
4. Confirm that logged-out users cannot see private data.

Email plus password covers most apps. Add Google login later if you need to cut sign-up friction.

How do you wire up Stripe payments?

Use Stripe Checkout rather than hand-building a payment form — it handles cards, taxes, and receipts, and keeps you out of PCI scope. Ask Lovable 3 to create a pricing page, a checkout redirect, and a webhook endpoint that marks a user as paid in Supabase when Stripe confirms the payment. Never trust the browser to say a payment succeeded; only the webhook should flip the subscription flag.

Things people get wrong

• Granting access on the front-end redirect instead of the webhook.
• Forgetting to handle failed and refunded payments.
• Hardcoding prices in two places instead of one source of truth.
• Skipping test mode; always run Stripe’s test cards first.

What does this cost?

Lovable 3 charges per generation, so each iteration toward payments costs credits. Supabase has a free tier that suits a small app and paid plans as it grows. Stripe takes a percentage plus a per-transaction fee. The main budget risk is Lovable credits spent on back-and-forth fixes, so write precise prompts and test one change at a time.

Is the result production-ready?

For a small SaaS, mostly. You will still want to review the webhook logic, add error handling, and export the code to GitHub so you can maintain it in a proper editor. Treat Lovable 3 as the builder and yourself as the reviewer — that pairing ships faster than either alone.

Quick Summary

• Add auth before data, and data before payments, to avoid rework.
• Supabase handles logins; protect private routes and test them logged out.
• Use Stripe Checkout and confirm payment in a webhook, never the front-end.
• Handle failed and refunded payments, and keep prices in one place.
• Export to GitHub for production maintenance.

What is Lovable 3?

Lovable 3 is the 2026 version of Lovable, an AI app builder that generates full-stack projects. You describe the app in chat, it produces the code, and you can iterate by asking for changes. It integrates with Supabase for auth and data, and deploys to a hosted URL. Plans start free with limited generations; paid tiers run from around $25 per month.

How do you go from prompt to app?

1. Start a new project and write one clear paragraph: what the app does, who uses it, and the core screens.
2. Let Lovable 3 generate the first version.
3. Click through the preview and list what is wrong in plain English.
4. Connect Supabase if you need logins or stored data.
5. Iterate in small steps — one change per message.
6. Publish to a live URL when it is ready.

How good is the generated code?

It is a standard React and TypeScript stack, and it runs. The code is not always organized the way a senior engineer would write it, and large apps accumulate repetition. You can export to GitHub and edit in an editor like Zed 2 when you outgrow chat. For MVPs and internal tools, the quality is more than adequate; for a long-lived production codebase, plan to refactor.

What are the limits?

Complex authentication, background jobs, and third-party API integrations often need manual work. The AI can lose track of a large app and undo earlier features if you give vague instructions. Credits are consumed per generation, so heavy iteration costs real money, and the free tier runs out quickly. Keep your prompts specific to avoid burning credits on rewrites.

Who is Lovable 3 for?

Founders validating an idea, designers who want a clickable product, and teams building internal dashboards. It is a poor fit if you need fine-grained performance tuning or are locked into a specific framework. Treat the first output as a prototype you refine, and export the code before you depend on it.

Quick Summary

• Lovable 3 builds full-stack web apps from a text description.
• Integrates with Supabase for auth and data; deploys to a hosted URL.
• Generates a standard React/TypeScript stack you can export to GitHub.
• Free tier is limited; paid plans start near $25/month, billed per generation.
• Great for MVPs and internal tools, weaker for complex production systems.
