Best for
  • Teams operating at large scale
  • Billion-vector search workloads
  • Enterprise RAG and search
  • Teams that want zero infrastructure ops
  • RAG and semantic search applications
  • Startups moving fast to production
Pros
  • Open source under Apache 2.0, free to self-host
  • Proven at billion-vector scale
  • Distributed, cloud-native architecture
  • Multiple index types and GPU acceleration
  • Hybrid search and rich filtering
  • Fully managed with no infrastructure to operate
  • Serverless model scales storage and compute independently
  • Low-latency similarity search at large scale
  • Hybrid (dense + sparse) search and metadata filtering
  • Integrated embedding and reranking inference
Cons
  • Operationally heavy to self-host at scale
  • Multi-component architecture adds complexity
  • Overkill for small or simple projects
  • Steeper learning curve than embedded databases
  • Zilliz Cloud compute-unit pricing needs modeling
  • Proprietary, closed source, no self-hosting
  • Usage-based billing can be hard to predict at scale
  • Undocumented capacity fees have drawn criticism
  • Vendor lock-in with no open data format
  • Less control over tuning than self-managed databases
