.NET vs Node.js — when to pick which backend.

Both are fast, mature and shippable. The right answer depends on the workload — regulated and stateful favour .NET, AI-native and high-velocity product surfaces favour Node.

/// Origami's take

Default to Node.js for content, commerce and AI products. Reach for .NET when the workload is regulated, stateful, or audit-heavy — auctions, gaming and fintech in particular.
