Overview
Langflow is another open-source LLM visual orchestration tool, competing in the same track as Flowise and also based on LangChain. After being acquired by DataStax in 2024, it gained enterprise-level resources. It has 50K+ stars on GitHub, a native Python ecosystem, and high compatibility with the data science community.
Compared to Flowise (Node.js stack), Langflow is based on Python, natively compatible with data science toolchains like Jupyter and pandas, making it more suitable for data scientists and researchers. DataStax's backing gives it an advantage in enterprise deployment, especially with Astra DB vector database integration.
Key Features
- Python Native: Based on Python + LangChain Python version, perfectly compatible with Jupyter/pandas
- Drag-and-Drop Visual Orchestration: Node-based UI, supports complex LLM/Agent workflows
- Deep DataStax/Astra DB Integration: Natural choice for vector database selection
- Multi-Model Support: Full coverage of OpenAI/Claude/Gemini/Ollama/HF/Bedrock
- API Export: One-click generation of Python SDK / REST API from Flow
- Langflow Desktop: Desktop client for local operation
Use Cases
- LLM prototyping for data scientists and ML engineers
- RAG based on Astra DB/Cassandra
- LLM experimentation environment for researchers
- LLM integration for Python-heavy projects
- Enterprise LLM platform (with DataStax)
Pros
- Python ecosystem friendly, data science compatible
- Sufficient resources after DataStax acquisition
- Tight integration with LangChain ecosystem
- Desktop client lowers trial barrier
- Open source, self-deployable
Pricing
The open-source version is completely free. DataStax's official hosting (Langflow Cloud) is billed based on usage. The enterprise version bundles services like Astra DB.
Summary
Langflow is the Python version of Flowise—more integrated with the data science ecosystem, with an enterprise channel backed by DataStax. Python teams choose Langflow, Node teams choose Flowise, and for out-of-the-box use, choose Dify.
Version History
- Langflow 1.5+ (2026): After DataStax acquisition, launched Astra DB integration version, enterprise features (authentication/audit/RBAC) mature, supports LangGraph state machine
- Langflow 1.0 (2024-2025): Visual orchestration based on LangChain, competing with Flowise in the same track
