Milvus.io PHP API Client
github.comA PHP client for the Milvus vector database's REST v2 API, built on Saloon, with an optional Laravel service provider and facade.
skeg
github.comA multi-tenant vector database and key-value store in one process that speaks the Redis protocol, keeping full-precision vectors on SSD with only a small quantized working set in RAM.
RAMen
github.comAn in-memory data store that speaks the Redis wire protocol as a drop-in cache, while adding native vector search, semantic caching of AI answers by meaning, and a built-in MCP server so agents can use it as a tool directly.
Vektor
centamiv.github.ioA native PHP vector database that stores data in binary files on disk rather than in memory, using HNSW indexing for approximate nearest-neighbor search.
Rostam
docs.rostamlabs.comA vector database and sub-microsecond key-value store in one Go engine, runnable as a standalone server, a Raft-replicated cluster or an embedded library, with an MCP server for agent memory and an LLM response cache.
Vector DB Manager
github.comA web-based management dashboard for Weaviate and Qdrant vector databases, covering collection management, object CRUD, vector and text search, and cluster statistics.
Convex RAG Component
github.comA Convex component for semantic search over text chunks and embeddings, used to give an AI agent retrieval-augmented context, with per-user namespaces, custom filtering and importance weighting.
Brain
github.comA Rust memory database for AI agents that stores typed memories, entities, statements and relations with provenance and bi-temporal validity, and answers queries by fusing semantic, lexical, graph and temporal retrieval.
laya-jev-GraphRAG
github.comAn Agentic GraphRAG framework that separates the AI decision layer from the graph database, running the same ingestion, retrieval and evaluation pipeline across Neo4j, Memgraph, Apache AGE and Kuzu.
Knolo
knolo.devA format and runtime that packages organizational knowledge as a single portable, cryptographically verifiable file so it can be mounted, queried and proven rather than trapped inside one application's database.
LynseDB
birchkwok.github.ioA Python-first vector database with a Rust storage and search core, designed to move from an embedded local prototype to an HTTP service and then a lightweight sharded cluster without changing the client API.
ZizkaDB
db.zizka.aiA self-hosted operational database for auditing AI agent behavior, recording each step's causal chain back to the user message so a team can answer why an agent called a given tool.
GigaVector
jaywyawhare.github.ioA vector database library written in C with Python bindings, covering twelve indexing algorithms, five distance metrics, and search features such as hybrid, filtered, geo-spatial and grouped search.
VortexDB
vortex-db.sdslabs.coA vector database built from scratch in Rust, organized as a workspace of modular crates with pluggable indexers, storage backends, and HTTP, gRPC and terminal clients.
rupixel
github.comA Rust port of PixelRAG that searches documents and video by how a page or frame visually looks rather than only by its text, using screenshots of pages turned into visual embeddings and an approximate-nearest-neighbor index.
AI-Lake Format
github.comA vector-native data lakehouse file format, written in Rust and built on the Apache Iceberg specification, that stores tabular data, embeddings and an HNSW vector index together in one self-contained Parquet-extended file.
Ravel
github.comA distributed database for OpenTelemetry metrics, logs and traces whose only durable storage is an object store, so a strictly acknowledged write survives the crash of any Ravel process with no write-ahead log or replicated ingest layer.
qdrant-haystack
github.comA Python integration that lets the Haystack framework use Qdrant as its document store, as a drop-in replacement for other vector embedding stores.
SochDB
sochdb.devAn embedded, ACID-compliant database that combines SQL tables, vector and keyword search, and a bi-temporal knowledge graph in one engine and file, and assembles token-budgeted context for an LLM in a single query.
QQL — Qdrant Query Language
pavanjava.github.ioA SQL-like query language and command-line shell for the Qdrant vector database, letting a developer write insert, search and filter statements instead of calling the Qdrant Python client directly.
Pinecone Java SDK
github.comThe official Java client library for the Pinecone vector database, letting JVM applications create and query Pinecone indexes over a shared HTTP client.
AionDB
aiondb.xyzA Rust database that speaks the PostgreSQL wire protocol and adds vector and graph access paths on top of the same catalog and on-disk storage engine. It is alpha software, not for production data.
YantrikDB
github.comAn embeddable Rust memory engine for AI agents that manages what is remembered instead of only storing it, applying temporal decay, contradiction detection, consolidation and a knowledge graph.
turbo-graph
github.comA fork of the turbovec vector search library that adds a graph-memory layer, letting a single query filter retrieval results by tenant, tag, source and time alongside vector similarity.
