Where each one falls short

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

esbuild

  • Plugin API is far narrower than webpack or Rollup, and complex builds hit its limits
  • Code splitting support has historically lagged the more established bundlers
  • Frequently used indirectly through Vite, so direct use is a narrower need than the download numbers suggest

v0 by Vercel

  • Free plan is capped at 7 messages per day and 5 USD of included monthly credits, and Plus tier costs 30 USD per user per month
