Read the full description
NexaFlow goes beyond traditional visual programming by turning existing JavaScript into interactive, executable node graphs. Unlike typical flowchart tools, it combines source-code parsing, sandboxed simulation, execution tracing, variable watchpoints, and spectrum-style activity heatmaps. Developers can visualize complex logic, track variable changes, investigate bugs, and build or export functions visually—all within one integrated environment.

Partial The graph UI and simulation view are buildable, but reliably parsing arbitrary JavaScript into executable node graphs with sandboxing, execution tracing, and watchpoints requires compiler and runtime expertise that vibe coding will struggle to get right.
What it would actually take: The stack would combine a JS parser (Acorn or Babel) for AST extraction, a sandboxed runtime (isolated VM or Web Workers) for simulation, and instrumentation that records execution events to drive heatmaps and watchpoints. Mapping control flow from source into a faithful, editable node graph is the hard part, and it needs strong knowledge of JavaScript semantics and program analysis.
