How to Add Payments and Auth to a Lovable 3 App
A Lovable 3 prototype becomes a business when it takes money and knows who is paying. Here is how to add Stripe checkout and Supabase…
Lovable 2 builds full-stack web apps from a prompt and now handles auth, databases and Stripe checkout without leaving the browser.
Lovable 2 is a prompt-to-app builder from Lovable AB in Stockholm. You describe an app in plain English; it generates a React and TypeScript front end, wires up a Supabase database, and can add Stripe billing. Everything runs in the browser.
It’s a Swedish product that grew out of the GPT Engineer project and went viral in 2025. You get a chat panel on the left and a live preview on the right, with a code view you can sync to GitHub.
Version 2 added agentic multi-step edits, so it can change several files from one instruction instead of one file at a time.
There’s a free tier with a small daily credit allowance — enough to try one or two prompts. Pro is $25/month for 100 monthly credits, Business is $50/month for 200, and top-up credit packs exist when you run dry mid-project.
