Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
