Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
