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
