The short version

  • Each has a real cost: Preact compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose; TypeScript requires build/compilation step; adds complexity to development workflow
  • They diverge on capability: Preact covers 3kB runtime, TypeScript covers Static typing.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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

TypeScript

  • Requires build/compilation step; adds complexity to development workflow
  • Performance slower than compiled languages like Rust or Go when running on same hardware
  • Type safety only at compile-time; runtime errors still possible if types are misused
  • JavaScript ecosystem requires understanding both TypeScript and JavaScript

Answered from the vendors’ own pages

Preact: Is Preact free?

Yes, open source under the MIT licence.

TypeScript: What is TypeScript?

TypeScript is an open-source programming language developed by Microsoft that adds static type checking and object-oriented features to JavaScript while compiling down to standard JavaScript.

Source
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.

TypeScript: When was TypeScript released?

TypeScript was publicly announced on October 1, 2012, by Microsoft after two years of internal development. Version 0.8 was the first release.

Source
Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.

TypeScript: Is TypeScript free?

Yes. TypeScript is open-source under the Apache 2.0 license and free to use for commercial and non-commercial purposes.

Source
TypeScript: What is the latest version of TypeScript?

As of February 28, 2025, TypeScript version 5.8 is the latest release.

Source
TypeScript: Does TypeScript require a compilation step?

Yes. TypeScript code must be compiled to JavaScript before execution in browsers or Node.js. This adds a build step to your development workflow.

Source
TypeScript: Can I use TypeScript everywhere JavaScript runs?

After compilation to JavaScript, yes. TypeScript compiles to standard JavaScript that runs in any JavaScript runtime including browsers, Node.js, and Deno.
