ObjectBox Vector

Embedded NoSQL database enabling low-latency on-device vector search for offline GenAI on mobile/IoT/browsers via ANN indexing. ACID-compliant with sync replication for edge RAG; more mobile-focused and offline-capable than cloud Qdrant.

Compact 2MB standalone database for low-latency vector search on IoT/mobile/embedded, no server needed for on-device real-time AI ops.

Lightweight embedded vector store for low-latency on-device vector operations in prototyping AI apps, using HNSW for fast ANN search with built-in embeddings and metadata filtering. Enables quick local RAG on edge devices; simpler and lower-latency than cloud Qdrant for developer workflows.

Lightweight Node.js library for low-latency on-device vector similarity search using HNSW and BM25 hybrid, with CRUD, metadata filtering, and persistence for edge RAG pipelines. Enables real-time semantic search without servers; more lightweight than cloud Qdrant.

Minimal Rust library for fast on-device cosine similarity search with Rayon parallelism and embedded persistence, ideal for low-latency prototyping on edge hardware. Supports quick inserts/queries for real-time AI; lighter than full DBs like Qdrant edge.

Pure Rust embedding database as lightweight Axum server for low-latency on-device vector search scaling to 100M+ vectors in memory. High accuracy/speed for edge RAG; simpler than Qdrant edge.
