Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deno

  • Egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications
  • CPU time overage is $0.10/hour on Pro and Builder tiers, adding to costs for compute-intensive workloads
  • Enterprise pricing is not disclosed; requires sales contact

MUI

  • Escaping the Material Design look takes more theming effort than teams expect
  • Bundle size is significant, and careless imports pull in far more than needed
  • Advanced components such as the full data grid require a paid licence
  • Major version upgrades have historically required real migration work
