Answered from the vendors’ own pages

Qwik: How does Qwik achieve instant interactivity without hydration?

Qwik uses resumability, serializing application state and component tree, then deserializing directly into memory without re-executing component code.

Source
Swagger UI: Is Swagger UI free?

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

Qwik: What is the typical JavaScript bundle size for a Qwik application?

Qwik applications boot with approximately 1kb of JavaScript regardless of complexity, with additional code loaded on-demand.

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.

Qwik: Can Qwik be deployed to edge computing platforms?

Yes, Qwik supports deployment to Cloudflare Workers, Netlify Edge, Vercel Edge, AWS Lambda, and many other edge platforms.
