Hands-on reviews & guides
FAQs about ai app builders
What is an AI app builder?
An AI app builder turns plain-English prompts into a working web application — frontend, database, authentication and deployment included. Unlike AI code editors (Cursor, Windsurf), they target people who don't want to see code at all.
Which AI app builder is best for non-developers?
In our hands-on tests, Lovable produced the most complete apps with zero code edits — working auth and database in 15 minutes. Replit is the better pick if you want to gradually learn to code along the way.
Can these tools build production-ready apps?
For MVPs and internal tools, yes — our Lovable test build handled real Stripe payments. For products with heavy custom logic, plan to export the code and continue in an editor like Cursor.
Do I keep the code these tools generate?
The good ones give you full export: Lovable and Bolt push complete repos to GitHub, and editor-based tools (Cursor, Windsurf) work on your own files by definition. Avoid anything without an export path.
