Why use Plugsky for AI:
The Vector Database Comparison is a free page for weighing popular vector stores: Pinecone, Weaviate, Qdrant, Chroma and Milvus. It frames the comparison around performance, scalability and pricing, the three factors that most often decide a RAG or semantic-search architecture. It is aimed at developers and architects choosing a store before building. No sign-up is required. Test candidates on your own data, because recall and latency depend on your embeddings and queries.
There is no universal winner. Chroma and FAISS suit prototypes and embedded use, Qdrant and Weaviate offer strong self-hosted production features, Milvus targets large scale, and Pinecone is fully managed. Decide by scale, filtering, operational capacity and budget.
Index a representative slice of your corpus with the embedding model you plan to use, then measure recall against known answers, query latency at expected concurrency, and memory or cost per million vectors. Include filtering and update workloads, since those often decide real-world behaviour.
For small collections, PostgreSQL with pgvector may be enough and simpler to operate. Dedicated stores become worthwhile when collections grow into millions of vectors or you need advanced filtering, sharding and hybrid search.
