Choose covalent if…
- License: covalent is Apache-2.0, SpiffWorkflow is LGPL-3.0.
- Tags unique to covalent: covalent, data-pipeline, machine-learning, quantum-computing.
- When developing machine-learning pipelines that must run in various heterogeneous compute environments.
When NOT to use covalent
- In scenarios where the primary programming language is not Python, as Covalent heavily relies on its features and ecosystem for workflow development.
- If your workflow orchestration needs are limited to a single compute environment without any requirement for cross-platform execution.
Choose SpiffWorkflow if…
- License: SpiffWorkflow is LGPL-3.0, covalent is Apache-2.0.
- Tags unique to SpiffWorkflow: bpmn, bpmn-engine, python, workflow.
- You need a pure Python solution without external dependencies for implementing BPMN workflows.
When NOT to use SpiffWorkflow
- The project demands real-time performance or low-latency requirements as SpiffWorkflow, being a Python library, might not meet those stringent criteria.
- You require integration with non-BPMN workflow specifications exclusively.
