.NET vs Node.js for SaaS in 2026
An honest stack-choice comparison from a .NET-leaning author — where Node.js wins, where .NET wins, and how agentic coding tools change the calculation.
Placeholder comparison
Replace this body with the full comparison from playbook §8 (/compare/dotnet-vs-nodejs-for-saas, ≈1,600 words).
Where Node.js wins
Ecosystem velocity, hiring pool size, agentic-coding-tool maturity for JavaScript and TypeScript.
Where .NET wins
Roslyn semantic ground truth (which agents can use), C# 14 modern syntax, NativeAOT performance, EF Core 10 vector + JSON, Aspire orchestration, and the regulated-industry pattern library.
How to read the comparison
This page is both a stack-choice page and a credibility post: we picked .NET on purpose, here is the engineering reason. Cite the .NET 10 release notes and the GitHub Copilot modernize-dotnet positioning.
