Lovable: when the goal is a product
Lovable is a prompt-to-app builder, previously known as GPT Engineer. You describe the product in chat and it generates and edits a full-stack app, including UI and backend pieces. It is the opinionated pick here when the goal is a product, not an editor.
Watch for: You will want a normal repo once the product sticks It has the lowest price-value score of the three (5).
Bolt: when you want to click it now
Bolt is StackBlitz's prompt-to-app product at bolt.new. You describe an app, it generates a project, and the app runs in a browser-based environment. It is the pick when you want a sandbox you can click immediately and you are comfortable exporting later.
Watch for: Generated projects still need a human once the edges show
v0: when you need screens, not a company
v0 is Vercel's AI tool for generating UI. You prompt it and get React and Tailwind code you can drop into a project, often a Next.js app on Vercel. It is the pick for interfaces, not for a whole company backend.
Watch for: Not a full product builder on its own It has the best price-value score of the three (7).
The StackPick path
Start in a generator until the demo works, and leave when the diff starts to matter. See the Prompt an app into existence and Design to deploy stacks: generate UI with v0, finish it in Cursor, host on Vercel.
