Pinecone alternatives

The short answer

3 tools on this index are recorded as a substitute for Pinecone. 1 of these runs the same way you already deploy Pinecone (saas), and 2 are permissively licensed, so they do not change what you can ship. All of them sit in Retrieval & Vector Stores, so the choice is a real one rather than a category change. There is no overall winner here: which one is right depends on traffic shape, operational budget and how much of Pinecone you have already built around.
