Pinecone vs Weaviate

Two sides of the vector database decision: managed vector store and open-source vector store. When each fits, what it costs, who moves from one to the other, and what makers who chose it say.

Which fits you

Choose Pinecone if
  • You want a hosted index with nothing to operate

Use it whenYou want vector search without running any infrastructure.

Trade-offClosed source and cloud-only, so leaving means re-indexing somewhere else.

Choose Weaviate if
  • You need an open-source store with heavy filtering or hybrid search, self-hosted or managed

Use it whenUsers search with both exact terms and meaning, and you want both in one query.

Trade-offMore concepts and configuration to learn than simpler stores; some advanced features need a license key.

Cost as you grow

Both cost $0 up to 100k vectors; from 500k vectors Pinecone costs less ($20 vs $126); from about 5M vectors Weaviate does ($1,263 vs $2,532). They're different kinds of tool — managed vector store and open-source vector store — so the prices don't buy the same thing.

What makers say

Makers on using it for vector database, from Product Hunt and Starter Story interviews, each linked to the source. Products with a page of their own and fuller notes first.

On Pinecone
TwelveLabs uses Pinecone to efficiently store and search the vector embeddings produced by our embedding model, enabling fast, scalable retrieval across large video and text datasets.
TwelveLabs, the makerSep 2026 ↗
Though we are using function tools to retrieve information from our integrations in real-time, we also use Pinecone to retrieve relevant long-term information.
Tometo, the makerSep 2026 ↗
We needed a vector database that's fast, reliable, and serverless for our RAG system. Pinecone was the easiest to set up and performs consistently at scale.

To store all our vector embeddings, now a staple for us to build forward. Their automatic 'load balancing' on which vectors are recently used is a game changer for system optimization
Quantera.ai, the makerSep 2026 ↗
Unbody is built on top of Weaviate, making Unbody content API run 100% on a vector database. Weaviate modular architecture as well as user-friendly GraphQl API has played a vital role in our product.
Unbody, the makerSep 2026 ↗
Weaviate gives us fast, semantic search across unstructured call data, crucial for surfacing insights in real time. Its native vector support and scalability made it the best fit for building an AI native platform like Insight7.
