A lightning-fast search engine API bringing AI-powered hybrid search to your sites and applications.
Rust59,253 starslast pushed 12 hours agoqdrant
Qdrant - High-performance, massive-scale Vector Database and Vector Search Engine for the next generation of AI. Also available in the cloud https://cloud.qdrant.io/
Rust34,492 starslast pushed 4 hours agoweaviate
Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native database.
Go16,801 starslast pushed 7 hours agoparadedb
One Postgres for your application data, full-text search, vector retrieval, and aggregations. Home of the pg_search extension.
Rust9,251 starslast pushed 42 minutes agoinfiniflow
The AI-native database built for LLM applications, providing incredibly fast hybrid search of dense vector, sparse vector, tensor (multi-vector), and full-text.
C++4,706 starslast pushed 2 days agooceanbase
The AI-Native Search Database. Best for agent storage, it unifies vector, text, structured, and semi-structured data into a single engine. This all-in-one database makes agents smarter, easier to run, and more stable.
C++2,924 starslast pushed 46 minutes agozilliztech
A persistent, unified memory layer for all your AI agents (e.g. Claude Code, Codex, DSH), backed by Markdown and Milvus.
Python2,588 starslast pushed 2 hours agovearch
Distributed vector search for AI-native applications
Python2,325 starslast pushed 2 months agoxerj-org
XERJ is the new way for AI to search data. Its autoindex capability activates agents to know your data without the token waste of grep and sed. One command indexes code, docs, logs and PDFs for search, RAG, security audits and agent memory, using 40x fewer tokens than grep. Elasticsearch compatible, so existing clients just work.
