Weaviate
Weaviate is an open-source vector database with native support for multi-modal search, combining vector similarity with structured filtering and built-in vectorization modules. Self-hosted free; Weaviate Cloud starts at $25/month. Stronger feature set than Pinecone for multi-modal use cases.
Weaviate is worth choosing when you need multi-modal search, built-in vectorization, or a rich feature set for complex retrieval patterns. Teams doing straightforward text RAG who want the simplest managed experience should still start with Pinecone or try pgvector first.
