Is Zilliz or Pinecone better?

Neither clearly leads. Zilliz starts at Free and Pinecone at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Zilliz or Pinecone?

Zilliz starts at Free and Pinecone at Free.

Does Zilliz or Pinecone run on more platforms?

Zilliz runs on Cloud, Self-hosted. Pinecone runs on Web.

Can I use Zilliz for free?

Both have a free tier, so you can try either at no cost before committing.

What is Zilliz best used for?

Zilliz is most often used for build retrieval-augmented generation (rag) systems, implement semantic search over documents, create multimodal search with text and images, power recommendation engines with vector similarity. Of those, build retrieval-augmented generation (rag) systems and implement semantic search over documents are not what Pinecone is typically brought in for.

What can Zilliz do that Pinecone cannot?

Zilliz covers Vector indexing, Distributed architecture, SQL interface, Tensor support. Pinecone covers Vector similarity search, Metadata filtering, Namespace partitioning, Real-time updates.

The short version

Each has a real cost: Zilliz pricing structure not publicly disclosed, requires sales contact; Pinecone reads and writes are billed on separate meters, and reads are far more expensive, at $16 to $18 per million against $4 to $4.50 for writes on Standard
They diverge on capability: Zilliz covers Vector indexing, Pinecone covers Vector similarity search.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Zilliz

Pricing structure not publicly disclosed, requires sales contact
Operational complexity for self-hosted Milvus deployments
Learning curve for those unfamiliar with vector databases
Limited built-in analytics compared to some alternatives

Pinecone

Reads and writes are billed on separate meters, and reads are far more expensive, at $16 to $18 per million against $4 to $4.50 for writes on Standard
Unit prices vary by region, so the same workload costs different amounts in different places
The Standard plan carries a $50 monthly minimum and Enterprise $500, charged whether or not the usage reaches it
Enterprise pays more per unit as well as more in minimum, at $24 to $27 per million reads against Standard's $16 to $18
Indexes and namespaces are capped by plan, at 5 indexes on the free tier and 20 on Standard
RBAC and SSO require the Standard plan
