What each one is
LanceDB
LanceDB is an open-source, embedded vector database built on the Lance columnar format, offering fast vector search with zero servers to manage.
- Embedded, no server to run
- Built on the fast Lance format
- Handles vectors plus metadata and files
Marqo
Marqo handles embedding generation and vector search together, so you send text or images and it does the rest — no separate embedding step.
- Embeddings generated for you
- Text and image search out of the box
- No separate embedding pipeline
