Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
