## Decision facts: langflow

- **Adopt for:** Langflow is a Python-based tool for building and deploying AI-powered agents and workflows, supporting multiagent systems and integration with large language models.

## Choose when

### Choose loonflow if…

- loonflow is primarily TypeScript; langflow is Python.
- License: loonflow is AGPL-3.0, langflow is MIT.
- Tags unique to loonflow: devops, django, mcp, python.
- You need a fully open-source solution for your internal process automation, as Loonflow requires you to share modifications if used in a SaaS service publically.

### Choose langflow if…

- langflow is primarily Python; loonflow is TypeScript.
- License: langflow is MIT, loonflow is AGPL-3.0.
- Tags unique to langflow: agents, chatgpt, generative-ai, large-language-models.
- Also covers AI Agents.
- When you need to develop AI agents and workflows that can integrate with large language models, as Langflow supports this integration directly.

## When NOT to use loonflow

- You seek closed-source solutions for proprietary reasons as Loonflow's AGPLv3 requirement mandates openness in SaaS settings.
- When deployment flexibility is essential since the tool relies on Docker for installation, which may not align with all IT environments.

## When NOT to use langflow

- If your project does not require the use of large language models or multiagent systems, as Langflow's strengths lie in these areas.
- When you are working in an environment that does not support Python 3.10–3.14, as Langflow requires this specific version range.
- If you are looking for a tool that does not require the use of the uv package manager, as Langflow recommends uv for installation and running.
