## Common questions

### What are the best alternatives to rag_api?

Graph-backed alternatives to rag_api include ChatGLM-6B, chroma, llm-app, meilisearch, qdrant. GraphCanon ranks them by typed relationship edges and constraint overlap from decision_facts - not marketing votes or raw star sort.

### How does GraphCanon rank rag_api alternatives?

Direct alternative and successor edges from the knowledge graph come first, ordered by edge type and shared constraint facets (persona, runtime, hosting). Category neighbours fill the list only after curated edges. Stars are shown for context, not as the primary sort.

### When should I avoid rag_api?

Avoid using if your project cannot leverage PostgreSQL/pgvector due to license or compatibility constraints. Not recommended for scenarios where high-level orchestration of multiple APIs and services is necessary without a direct need for FastAPI's simplicity.

### Is rag_api open source?

Yes. rag_api is an open-source project on GitHub under the MIT license, with 863 stars.

### What is rag_api used for?
