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

Fireflies.ai

  • Video recording limits by tier: Free tier has 2 hours, Pro tier 2 hours, Business tier 3 hours, Enterprise tier 4 hours
  • Storage quotas on Free and Pro tiers: Free tier limited to 400 minutes per team, Pro tier limited to 8,000 minutes per seat
  • AI credits allocation varies by tier, with lower tiers receiving limited credits for advanced AI features
