Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
