The honest brief

LanceDB

Runs in-process on the disk-efficient Lance format — no server, no port, zero-copy reads; strong on multimodal data.

  • Embeds in your app; runs on edge/desktop
  • Disk-efficient Lance format, low cost
  • Native multimodal (text, image, video)
  • Hybrid vector + full-text + SQL queries
  • Newer; smaller community than Qdrant/Milvus
  • Managed cloud tier still maturing
  • Multi-process concurrent access limits
  • Fewer framework integrations, less tooling

TopK

One query spans vector, keyword, and multi-vector search with custom ranking — no separate search + vector + reranker stack to stitch together.

  • Serverless, no infra to manage
  • Runs in your own VPC (BYOC)
  • Built-in embedding/OCR inference
  • Low latency at billion-doc scale
  • SDKs for Python, JS, Rust + MCP
  • Newer, smaller ecosystem than peers
  • No open-source self-host
  • Developer/API-first, no managed UI
  • Smaller community vs Pinecone/Qdrant
