When should I avoid LightRAG?

If your project does not require efficient knowledge graph augmentation or if speed and simplicity are not primary concerns. When you prefer not to use uv for package management and are satisfied with traditional methods like pip. In scenarios where the installation of additional libraries such as libcairo2 for handling SVGs in markdown/textpack documents is not feasible or desired. If your deployment environment strictly prohibits the use of external package managers like uv.

When should I avoid ragflow?

If your project does not require integration with external LLM and embedding services, as RAGFlow relies on these services.
