About wexflow
Wexflow Wexflow is an open source and cross platform workflow automation engine that supports a wide range of tasks, from file operations and system processes to scripting, networking, and more. Wexflow targets both developers and technical users who need automation (file ops, tasks, scheduling, alerts, etc.).

About redun
yet another redundant workflow engine redun aims to be a more expressive and efficient workflow framework, built on top of the popular Python programming language. It takes the somewhat contrarian view that writing dataflows directly is unnecessarily restrictive, and by doing so we lose abstractions we have come to rely on in most modern high level languages (control flow, composability, recursion, high order functions, etc). redun's key insight is that workflows can be expressed as lazy expressions, which are then evaluated by a scheduler that performs automatic parallelization, caching, and data provenance…
