So what is Nextbuild?
It's an environment for developing in BASIC for the Spectrum Next, which combined with MS VSCode (other editors are available!), ZXBasic compiler, and an emulator on a Windows, linux or apple PC gives pretty decent performance and Rapid development. It's a bunch of glue, plus a fairly extensive library, along with some examples, which allow access to a lot of the hardware banging functions of the Next with ease, at speeds you couldn't dream of in NextBasic. (Not NextBasic's fault of course - it's interpreted so is always going to have an overhead which NextBuild/ZX basic doesnt have.)
Contributions and ideas for Nextbuild are actively encouraged and there is a Boriel section on Discord which well used by users of Nextbuild.
