Neva is a statically typed, compiled dataflow programming language where programs are expressed as message-passing graphs that run in parallel by default. It compiles to Go (and then to machine code or WASM), interoperates with Go, and supports hybrid text/visual programming.

Use cases

• write concurrent programs without manual thread management
• model programs as dataflow graphs with message passing
• compile a new language to machine code via Go
• gradually adopt dataflow in existing Go codebases
• build programs visually with a node editor
• explore flow-based programming (FBP) with strong static types

When to choose

• you want implicit parallelism with static type safety
• your problem naturally maps to a graph of message-passing components
• you need Go ecosystem interop from a new language
• you want an LLM-friendly language for code generation

When to avoid

• you need a mature ecosystem with extensive libraries and tooling
• your team relies on mainstream control-flow paradigms and hiring pools
• you need guaranteed long-term stability for production-critical systems
• you need fine-grained control over scheduling or low-level performance tuning
