## Choose when

### Choose storm if…

- License: storm is MIT, deep-searcher is Apache-2.0.
- These are both open-source deep research tools that aim to offer RAG capabilities, indicating they serve similar purposes with potentially varying functionalities.
- Tags unique to storm: large-language-models, report-generation, retrieval-augmented-generation, knowledge-curation.
- Also covers LLM Frameworks.
- When you need a tool capable of generating comprehensive and cited reports based on deep research.

### Choose deep-searcher if…

- License: deep-searcher is Apache-2.0, storm is MIT.
- These are both open-source deep research tools that aim to offer RAG capabilities, indicating they serve similar purposes with potentially varying functionalities.
- Tags unique to deep-searcher: llm, openai, claude, milvus.
- Also covers Vector Databases, AI Agents.
- deep-searcher ships Docker support for self-hosted deployment.
- - **When you need a flexible embedding option**: DeepSearcher supports multiple embedding models like Milvus for optimal selection.

## When NOT to use storm

- Avoid STORM if cost optimization is critical as it may involve using multiple different models to balance between quality and expense.
- Do not choose STORM if you require a tool that does not modify its behavior through agentic-RAG processes, which are central to this system’s operation.

## When NOT to use deep-searcher

- - **If you require real-time web content integration only**: DeepSearcher primarily focuses on local/private data. Online content integration is possible but not its core functionality.
- - **When strict API dependency avoidance is needed**: DeepSearcher often relies on specific APIs (e.g., OpenAI) for LLM services, which might be a constraint in environments strictly avoiding third-党
