Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Still early. Manus is more flexible for less money.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for designer-led sites. S-tier if animations matter.
