In their own words
AllegroGraph
AllegroGraph is a persistent graph database for RDF triples and quads, generic graphs, and vectors, using disk-based storage and efficient memory utilization. It supports SPARQL, RDFS++ reasoning, and Prolog, plus geospatial and temporal reasoning, social network analysis, native data types, and range queries. The database is ACID-compliant and includes online backups, point-in-time recovery, replication, and warm standby. It can integrate with large language models and store embedding vectors in a vector database. Security features include role-based permissions, repository access controls, security filters, and triple-level controls using attributes. LDAP and OAuth/OIDC authentication are supported, with TLS for client connections; the security overview recommends third-party tools for encryption at rest. Clients include Java, Python, and Lisp, alongside REST and browser-based WebView access. The server runs natively on x86-64 Linux, with documented Docker, Windows Subsystem for Linux, virtual machine, and cloud options. The free edition costs nothing, has no expiration or license key requirement, and allows up to 5,000,000 triples.
