Dataflow programming language where you write a program as a message-passing graph and everything runs in parallel by default. It has strong static types, compiles to machine code, interoperates with Go, and supports visual programming with a node editor. Extremely LLM-friendly too.
Neva is a statically typed programming language in which programs are message-passing graphs: nodes exchange data through ports and run concurrently by default. It is for developers building compiled programs with dataflow control, visual editing, and interoperability with Go. The catalogue includes skills and instructions for working with Neva.
