Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier for designer-led sites. S-tier if animations matter.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
