| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | S-tier for solo + free. The best free option, hands down. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier for ops automation. B-tier for simple copy (use Claude). |
