Where each one falls short

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

esbuild

  • Deliberately does not type-check TypeScript, only strips types, so tsc still runs separately
  • 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

Kapwing

  • Free plan limited to 10 credits and watermarked exports
  • Pro plan restricted to 2-hour export limit
  • Enterprise plan requires custom pricing quote
