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 es una base de datos de grafos fuertemente tipada y un sistema de gestión de grafos de conocimiento. Sirve como un almacén de datos multimodelo que unifica estructuras relacionales, de documentos y de grafos en un solo entorno, funcionando tanto como una base de datos compatible con ACID como un motor de consultas declarativo. El sistema se distingue por el uso de modelado de hipergrafos n-arios y jerarquías de tipos polimórficos. Emplea un esquema fuertemente tipado para imponer reglas estructurales y validar la integridad de los datos, permitiendo la inferencia polimórfica basada en tipos y el polimorfismo de interfaz basado en roles para resolver relaciones complejas automáticamente durante la ejecución de consultas. La plataforma cubre una amplia gama de capacidades, incluyendo el cálculo de relaciones recursivas mediante tabulación, transacciones con aislamiento de instantáneas y recuperación declarativa de datos. También admite alta disponibilidad mediante replicación de clúster basada en consenso, control de acceso basado en roles e integración con agentes de IA para la recuperación de datos estructurados. La gestión se realiza a través de una interfaz de línea de comandos, y el sistema proporciona herramientas para visualizar esquemas de grafos y auditar la actividad administrativa.

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 es un motor de base de datos de grafos ligero que utiliza SQLite para persistir nodos y aristas. Funciona como un motor de grafos relacional mapeando estructuras de grafos en tablas de base de datos estándar, permitiendo el almacenamiento tanto de datos estructurados como de información flexible sin esquema mediante el embebido de documentos JSON. El sistema proporciona una utilidad para realizar recorridos de grafos complejos y descubrimiento de rutas aprovechando expresiones de tabla comunes recursivas. Este enfoque permite la exploración de conexiones profundas y secuencias de nodos conectados dentro de la red de datos almacenada. El proyecto admite operaciones estándar de gestión de datos, incluyendo la creación, actualización y eliminación de registros de grafos. Todas las interacciones se manejan mediante la ejecución de sentencias preparadas para asegurar una manipulación de datos consistente y segura dentro del almacenamiento relacional subyacente.
