While I agree it is not in the technical terms a runtime, the inspiration for it was from BunJS and Deno and such. Similar projects in the Lua space also name themselves as runtime, so I wrote runtime as well. It is not exclusively for web, although it started as that. Nowadays Astra has libraries for many general things, and are used in a wide range of projects, from scripting, CI/CD, API servers, and more.
Lua does ship a runtime, although it is incredibly limited in standard library, and lacks a lot of features that other languages ship out of the box. I could have either made a library to be used with each Lua VM or package everything into a single binary which was what we needed for our use case anyways, and gave a lot of control for us as well.
In any case, I agree that I should have been more clear in the description. It has not been updated since a while and the project moves very fast.
