Answered from the vendors’ own pages

Swagger UI: Is Swagger UI free?

Yes, open source under the Apache 2.0 licence. SmartBear sells commercial SwaggerHub separately.

Vite: Does Vite support CommonJS dependencies?

Vite automatically converts CommonJS dependencies to ES modules during pre-bundling using esbuild, but it does not support Node.js built-in polyfills. For projects requiring Node builtins, additional configuration may be needed.

Source
Swagger UI: What is the difference between Swagger and OpenAPI?

OpenAPI is the specification format; Swagger is the toolset around it, including Swagger UI. The specification was renamed from Swagger to OpenAPI in 2016.

Vite: Can Vite work offline?

Vite requires internet for initial dependency pre-bundling with esbuild. Once dependencies are pre-bundled and cached, development can continue with local file serving, but full offline development is not supported.

Source
Swagger UI: Can Swagger UI make real API calls?

Yes, through its try-it-out control, though authentication and CORS configuration often mean it is disabled for production APIs.

Vite: What are Vite's system requirements on Windows?

Vite can run on Windows, but WSL2 users may experience file watching issues where Vite cannot detect file changes in certain conditions. Windows users with project paths containing ampersands may encounter module resolution failures with npm.

Source
Vite: Does Vite support TypeScript, JSX, and CSS out of the box?

Yes. Vite natively supports TypeScript, JSX, CSS, and WebAssembly without additional configuration needed for basic use.
