TypeScript

JavaScript with syntax for types

As of 30 August 2026, TypeScript is free to use. TypeScript is a strongly typed programming language that builds on JavaScript. Softwr lists it under Web Development. TypeScript is made by Microsoft Corporation, launched in 2012, available on API, Web.

Overview

What TypeScript does

TypeScript is a strongly typed programming language that builds on JavaScript. Developed by Microsoft, it adds static type definitions and compiles to plain JavaScript, helping catch errors early in development.

What people use it for

  • Large-scale applications
  • Enterprise development
  • Type-safe JavaScript
  • Team collaboration
  • API development

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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

Softwr does not host reviews and shows no star rating for TypeScript, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
