Answered from the vendors’ own pages

Koha: How much does Koha cost?

Koha is free and open source. There is no software licensing fee. Development is sponsored by libraries, volunteers, and support companies worldwide.

Source

Yes, open source under the MIT licence.

While no specific pricing is detailed on the main site, Koha mentions paid support options available from support companies, but exact costs require contacting providers directly.

Source
SolidJS: Is SolidJS just React without the virtual DOM?

The syntax is similar but the model is not. Solid components run once and reactivity is fine-grained, so patterns that are correct in React can be wrong in Solid.

SolidJS: Why is SolidJS fast?

It compiles away much of the framework and updates individual DOM nodes directly, rather than re-rendering components and diffing a virtual DOM.
