Been testing AI tools against our llm API for building crypto apps for the last week:
- claude code: more efficient than most tools, knows to use create-react-app and other starter kits/guides. just costs the most.
- cursor: writes everything from scratch, somehow does a better job at testing everything (i.e. with curl requests etc for validation) even though it's just claude model. cheapest by far.
- replit: best design and file management structure, but agent memory is a mess (often mixes up messages). kind of pricy.
- v0: fastest model/implementation and best at complex state, but stuffs everything into like 3 files. design is also pretty boring/boilerplate. most fair pricing.
- lovable: could not get it to work lol, gave up on it
