Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Still early. Manus is more flexible for less money.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
