Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
