Head-to-head
Pinecone vs Weaviate: which one in 2026?
Pinecone is a hosted vector database from Pinecone Systems, Inc. that runs on serverless infrastructure and has no self-hosted edition. Weaviate is an open source AI database that can be self-hosted or bought as a managed cloud service. Both have free tiers, and their paid plans start at $20 and $45 a month.
Verdict
Weaviate is the safer pick when you may need to move the database yourself, since the code is open and Pinecone's own exit route is Bring Your Own Cloud. Pinecone wins on a simpler start: a flat $20 Builder tier and clearer certification wording. Neither opened trust page showed retention or AI training terms, and Weaviate's trust portal redirects to a third-party page. Treat compliance as a question for each vendor, not a point scored here.

Frequently asked questions
Can Pinecone be self-hosted?
No self-hosted edition appears on the pages read. Pinecone offers Bring Your Own Cloud, where it runs in your own cloud account, but it is quoted by sales, and Enterprise pricing lists it alongside private endpoints and customer-managed keys. Starter and Builder run only in Pinecone's own cloud.
How large is Weaviate's free cluster?
The Free plan allows 100,000 objects, 1 GB memory, 10 GB disk, one collection and up to 3 tenants on a shared deployment. It runs on AWS in two regions with best-effort availability and no backup retention, as of November 2026.
What does Pinecone charge once usage grows?
Standard has a $50 monthly minimum, then pay as you go: storage at $0.33 per GB a month, writes at $4 to $4.50 per million and reads at $16 to $18 per million, depending on cloud and region. Enterprise has a $500 minimum.
Do these vendors say whether customer data trains models?
Not on the pages read. Pinecone's trust page opened without detail, and Weaviate's security page does not address model training or retention periods. Request both statements in writing before you load sensitive data into either one. Weaviate's trust portal also redirects to a third-party page.
