The short version

  • Each has a real cost: .NET .NET 8 and .NET 9 both reach end of support on 10 November 2026, per dotnet.microsoft.com/en-us/platform/support/policy (Aug 2026), forcing an upgrade to .NET 10 by that date; esbuild deliberately does not type-check TypeScript, only strips types, so tsc still runs separately
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

.NET

  • .NET 8 and .NET 9 both reach end of support on 10 November 2026, per dotnet.microsoft.com/en-us/platform/support/policy (Aug 2026), forcing an upgrade to .NET 10 by that date
  • Standard Term Support releases get only 2 years of patches versus 3 years for Long Term Support releases, per Microsoft's own support policy page, so teams on an STS release face a shorter upgrade cycle

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
