A curated, link-checked directory of open-source and cloud engines for automating and sequencing distributed processes.
Workflow engines and orchestration tools coordinate the sequencing, retries, branching, and state of distributed processes — from serverless step functions to Kubernetes-native event pipelines. This directory lists engines that model work as directed graphs of tasks, whether the graph is authored as YAML, Python, BPMN, or a visual DAG builder.
