Reviewer scorecard
“pip install chromadb and you're running. The best DX for prototyping RAG applications. Move to Pinecone when you scale.”
“Built-in vectorizer modules mean less glue code. GraphQL API is intuitive. Self-hosting option is a huge plus.”
“Fine for prototypes but not production-ready at scale. No managed cloud, limited query capabilities. A stepping stone.”
“Open source and self-hostable gives you an exit strategy. The module system is genuinely innovative.”
“Democratizing vector search by making it dead simple. The SQLite of vector databases.”
“Multi-modal vectors and generative search point to where databases are heading. Weaviate is building for that future.”
