Weaknesses
  • Less flexible than raw code
  • Pricing per-site adds up

  • Less flexibility on custom configs
Kai's verdictA-tier for designer-led sites. S-tier if animations matter.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for speed. When latency is the product, start here.
