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

Lantern

Adds production vector search inside Postgres itself — HNSW indexing and hybrid BM25 search with no separate vector store.

  • Lives inside the Postgres you already run
  • Open-source, self-host or managed cloud
  • HNSW plus hybrid BM25 search
  • Built-in embedding generation
  • Tied to the Postgres ecosystem
  • Smaller community than pgvector
  • Managed cloud tier still maturing
