// EDITOR'S TAKE
Qdrant is the closest swap: one binary, strong payload filtering, and a managed cloud if you would rather not operate it, which is where most teams leaving Pinecone end up. Milvus scales further into the billions of vectors but hands you a distributed system to run, while Chroma is excellent for prototypes and local work and starts to strain well before that.
