Database
What you get
A free managed Milvus vector database cluster with 5 GB of storage (about 1M 768-dimension vectors), 2.5 million vCUs a month and up to 5 collections.
How to get it
Register on Zilliz Cloud and create the free cluster.
What it requires
A Zilliz Cloud account; Zilliz says no payment information is required.
The catch
Capped at 5 collections and community support; backups and other advanced features need a paid Serverless or Dedicated cluster.
