AllegroGraph is described as 'High-performance, persistent graph database. AllegroGraph supports SPARQL, RDFS++, and Prolog reasoning from numerous client applications' and is an app in the development category. There are nine alternatives to AllegroGraph for a variety of platforms, including Linux, Mac, Windows, Web-based and Self-Hosted apps. The best AllegroGraph alternative is neo4j, which is both free and Open Source. Other great apps like AllegroGraph are NetworkX, GraphStack.io, nebula graph and RedisGraph.

NetworkX is a Python language software package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.

GraphStack ™ is the name for the Neo4j Enterprise open source distributions compiled and packaged from the official Neo4j Github Repository by the Graph stack.io Team.
Nebula Graph is an open-source graph database capable of hosting super large-scale graphs with billions of vertices (nodes) and trillions of edges, with milliseconds of latency. It delivers enterprise-grade high performance to simplify the most complex data sets imaginable into...
RedisGraph is a property graph database module for Redis. It is the first graph database to use linear algebra on sparse adjacency matrices to implement graph operations, which lets it achieve high performance. It understands OpenCypher queries.
An embedded transactional graph engine for Python backed by a LMDB file. Works with Python 2.6, 2.7 and 3.x.
Graph Engine (GE) is a distributed, in-memory, large graph processing engine, underpinned by a strongly-typed RAM store and a general computation engine.
Dgraph is a low latency, high throughput, horizontally scalable and distributed graph database with ACID transactions.
