In their own words
esbuild
esbuild is a free bundler for web projects, designed to improve build-tool performance while remaining easy to use. It bundles ESM and CommonJS modules, including CSS modules, with built-in support for JavaScript, CSS, TypeScript and JSX. Optimization features include tree shaking, minification and source maps; development tools include a local server, watch mode and plugins. Developers can use the command-line, JavaScript or Go interface. The recommended installation is the native executable installed with npm. An alternative WebAssembly package works across platforms, though it can be substantially slower than the native package. esbuild is MIT-licensed. It does not type-check TypeScript, and its FAQ recommends running tsc separately. The FAQ describes code-splitting support as primitive. The maintainer says the project receives periodic releases and is maintained, but active feature development is not underway. The FAQ also notes that a project primarily built by one developer may not fit organizations seeking a larger or more active community.
TypeScript Playground
TypeScript Playground is a free browser environment for writing, running, sharing, and safely experimenting with TypeScript and JavaScript. It accepts .ts, .tsx, .js, .jsx, and .d.ts files. Run converts code to JavaScript, executes it in the current browser session, and shows console output in Logs; the browser session can also support DOM API experiments. The editor centers on one text document and is described as a teaching tool that needs no setup. Users can select supported TypeScript builds, including beta, nightly, pull request, and older builds. The TS Config panel exposes a focused compiler-option set, while twoslash annotations can configure options beyond it. URLs can preserve code, compiler flags, and settings for sharing. Export can create Markdown, open TypeScript AST Viewer, or export a project to CodeSandbox or StackBlitz. Plugins are supported, including Presentation Mode, Clippy, TSQuery, Collaborate, and Transformer. The mobile layout uses a single pane and does not show transpiled JavaScript beside source.
