Workflow Engine NEO is a separate product based on Workflow Engine, and you host it on your own servers. It comes with Workflow Designer, the same visual editor as Workflow Engine. Its four editions cover internal apps that need the HTTP API, public web apps and SaaS, and products that ship the engine inside. Form Engine is a separate product family for forms in React.
