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

Postman

  • Free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • Only 25 collection runs per month and 1,000 API calls/month on free tier
  • Removed local-only Scratch Pad mode in 2023, forcing cloud account creation and sync
  • Requires Postman account and internet connection for most features
  • Cloud-first architecture with mandatory syncing to Postman's cloud servers
  • No CI/CD integration or advanced security features on free plan
