How are AI App Builder AI tools ranked?
Tiers weigh capability, usability, value for money, and how actively each tool is maintained. Every tool publishes its tier rationale and pros/cons, and a weekly re-evaluation moves tiers up or down. The site is ad-funded, so a tier cannot be bought.
Can you ship what an AI app builder produces?
Prototypes and internal tools, yes. Production is where people get stuck — auth, database design, payments, and performance are the parts that need real work. Before committing, check whether the tool lets you export the code, and whether the exported code is something you could maintain yourself.
Bolt.new, v0, or Lovable — which should I pick?
It depends on what you are building. If you want UI components to drop into an existing React project, v0 fits. If you want a running full-stack app, Bolt.new or Lovable fit better. All three are credit-based, so your real cost is driven by how many iterations you need, not by the plan price.
