The short version

  • Only .NET has a free tier, so it costs nothing to try first.
  • 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; Express.js governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare

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

Express.js

  • Governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare
  • Express.js provides only a thin layer of fundamental routing features by its own description, requiring separate middleware modules for functionality like body parsing, sessions or authentication
