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
txtai
Unlike pure vector stores, it fuses dense + sparse vectors, graph networks, and a SQL database into a single embeddings DB.
- Fully open source (Apache-2.0), runs locally
- Vector + graph + SQL in one store
- Build with Python or YAML
- API bindings for JS, Java, Rust, Go
- Built-in RAG, agents, and pipelines
- Maintained by a small team, not a big vendor
- Smaller ecosystem than Pinecone/Weaviate
- No managed cloud offering
- More concepts than a plain vector DB
