Common reasons people leave Zilliz Cloud: compute-unit pricing takes effort to estimate before you run a proof of concept, and dedicated clusters have a monthly floor even when idle. We ranked 6 alternatives by how directly each one replaces Zilliz Cloud, then by reviews, real visits and how recently each app's facts were checked against its own website. Milvus currently ranks first.

    Open sourceSelf-hostableSelf-hosted, Linux

    66.5

    score / 100

    Why switch from Zilliz Cloud

    The same open-source engine, free to self-host if you'd rather run the clusters yourself.

    Pros

    • Apache 2.0 licence with no paid core
    • Same API from a local Python library up to a distributed cluster
    • Many index types, including disk-based and GPU indexes
    • Managed option available through Zilliz Cloud

    Cons

    • Distributed mode needs Kubernetes and has many moving parts
    • Heavier to operate than single-binary options like Qdrant or Chroma
    • Managed hosting is a separate product from a separate site

    Open sourceSelf-hostableSelf-hosted, Linux, macOS, Windows

    55.9
