Can I open-source Pinecone?
YES · mature open-source replacementYes. NocoDB (64k stars), Milvus (32k stars), Qdrant (22k stars) are mature open-source replacements for Pinecone — self-host in one command and stop paying $50/mo.
Because at real scale, vector index operations are their own engineering discipline and most teams would rather not hire for it.
