Where each one falls short

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

NestJS

  • Licensed under the MIT License per nestjs.com; the core framework has no paid tier, but the Enterprise support offering (architectural reviews, LTS, upgrade assistance) is sold by direct contact with no published rate
  • Built specifically on TypeScript and Node.js, per nestjs.com's own description, so it requires that runtime and cannot be adopted independently of the Node.js ecosystem

Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React

Preact: Can I use React libraries with Preact?

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.
