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

IAR Embedded Workbench

  • No pricing information published on product page; prospective customers directed to free trial or sales contact only
  • Pricing model not specified; customers must request quote or try free trial to understand licensing costs
  • Embedded development tools typically require expensive licenses, but specific IAR costs unavailable online
