Joget Workflow is Web-based workflow software made to develop workflow and Business Process Management applications. More than just a workflow or BPM platform, it offers full-fledged agile development capabilities (consisting of processes, forms, lists, CRUD, and UI), not just backend EAI/orchestration/integration or the task-based interface of traditional workflow/BPM products. It can, for example, build a CRM sales force automation app instead of just a sales quotation approval process. Video tutorials are provided.
