EdgeDB is a graph-relational database that combines a PostgreSQL backend with a graph-based schema and query language. It functions as an object-relational mapper and graph query engine, allowing data to be modeled as objects and links to align storage with modern programming language structures. The system features a composable query language designed to retrieve deeply nested or interconnected data without the use of manual SQL joins. It includes an integrated AI-driven data retrieval solution with built-in support for vector embeddings. The platform provides a schema migration tool for tr

Instant is a real-time backend as a service and relational graph database designed to synchronize data across clients automatically. It functions as a data synchronization layer that provides authentication, permissions, and relational data storage for web and mobile applications. The platform includes an optimistic UI framework that updates local interfaces immediately during writes and handles automatic server rollbacks. It also features a real-time presence system to broadcast transient user states, such as cursor positions and online status, to other connected clients. The system manages

CodeQL is a semantic code analysis engine and vulnerability scanning tool that treats source code as data. It utilizes a static analysis query language to define complex patterns and security vulnerabilities within a code graph database. The system represents source code as a relational database, enabling the execution of structural queries and data flow analysis. This approach allows for the detection of security flaws and coding errors across large-scale repositories. The tool provides capabilities for automated code auditing, static analysis security testing, and custom vulnerability dete

TypeDB هو قاعدة بيانات رسومية ذات نوع قوي ونظام إدارة قاعدة بيانات معرفية. يعمل كمخزن بيانات متعدد النماذج يوحد الهياكل العلائقية والمستندية والرسومية في بيئة واحدة، ويعمل كقاعدة بيانات متوافقة مع ACID ومحرك استعلام تصريحي. يتميز النظام باستخدام نمذجة الرسم البياني الفائق (n-ary hypergraph) وتسلسلات هرمية للأنواع متعددة الأشكال. يستخدم مخططاً ذا نوع قوي لفرض القواعد الهيكلية والتحقق من سلامة البيانات، مما يسمح بالاستدلال متعدد الأشكال القائم على النوع وتعدد أشكال الواجهة القائم على الدور لحل العلاقات المعقدة تلقائياً أثناء تنفيذ الاستعلام. تغطي المنصة مجموعة واسعة من القدرات بما في ذلك حساب العلاقات العودية عبر الجدولة، ومعاملات عزل اللقطات، واسترجاع البيانات التصريحي. كما يدعم التوافر العالي من خلال تكرار الكتلة القائم على الإجماع، والتحكم في الوصول القائم على الدور، والتكامل مع وكلاء الذكاء الاصطناعي لاسترجاع البيانات المهيكلة. يتم دعم الإدارة عبر واجهة سطر أوامر، ويوفر النظام أدوات لتصور مخططات الرسوم البيانية وتدقيق النشاط الإداري.

Apache AGE is a graph database extension for PostgreSQL that adds openCypher graph query capabilities directly within the relational database environment. It functions as a loadable extension that translates Cypher graph traversal queries into SQL expressions, enabling users to run pattern matching and path analysis alongside standard SQL operations within a single database instance. The extension stores labeled, directed property graphs as isolated schemas with internal relational tables for vertices, edges, and labels, preventing cross-graph interference. It supports hybrid query execution

FalkorDB is a high-performance graph database management system and vector graph database. It serves as a knowledge graph construction tool and a GraphRAG knowledge store, integrating structured property graphs with vector search to provide grounded context for large language models. The engine is designed as a multi-tenant graph engine, capable of hosting thousands of isolated datasets within a single instance. The system distinguishes itself by using linear algebra for query execution, treating relationship tensors as matrix multiplications to achieve low-latency multi-hop traversals. It ut

LogonTracer is a security auditing tool designed for logon analysis and forensic log auditing. It functions as a dockerized security auditor that utilizes a security event graph database to map account names and network addresses, allowing for the visualization of complex system compromise patterns and authentication paths. The system features a Sigma detection engine that scans imported event logs against standardized rule sets to identify known malicious activity. It also includes an anomalous behavior detector that applies statistical analysis, graph algorithms, and hidden Markov models to

Simple Graph is a lightweight graph database engine that utilizes SQLite to persist nodes and edges. It functions as a relational graph engine by mapping graph structures into standard database tables, allowing for the storage of both structured data and flexible, schema-less information through JSON document embedding. The system provides a utility for performing complex graph traversals and path discovery by leveraging recursive common table expressions. This approach enables the exploration of deep connections and sequences of connected nodes within the stored data network. The project su
