## Choose when

### Choose llm-workflow-engine if…

- License: llm-workflow-engine is MIT, viewflow is AGPL-3.0.
- Requirements: Built for a Python environment which may not fully cater to workflows outside of this language..
- Tags unique to llm-workflow-engine: chatbot, chatgpt, gpt-3, gpt3.
- Also covers LLM Frameworks.
- llm-workflow-engine ships Docker support for self-hosted deployment.
- When developing workflows around Large Language Models (LLMs), particularly if your projects are Python-based, to streamline model integration and management via CLI.

### Choose viewflow if…

- License: viewflow is AGPL-3.0, llm-workflow-engine is MIT.
- Tags unique to viewflow: bpmn, django, process-engine, workflow.
- When your project requires BPMN-compatible workflows integrated into Django, Viewflow offers a dedicated library optimized specifically for Django's ecosystem beyond generic Python。

## When NOT to use llm-workflow-engine

- Avoid using llm-workflow-engine if you need deep integrations with proprietary systems that are incompatible with MIT licensing terms and conditions.
- Do not use this tool if your primary development environment is not Python-based, as the effectiveness of the CLI and workflow manager might be limited without Python support.

## When NOT to use viewflow

- Avoid if your project strictly requires proprietary or closed-source licenses, as Viewflow’s AGPL v3 license mandates making source code available in certain usage contexts.
- This tool is not suitable for environments that cannot support Python 3.10 and Django 4.2 due to compatibility issues or legacy system constraints.
