In their own words
Eclipse RDF4J
Eclipse RDF4J is a modular Java framework for parsing, storing, querying, and reasoning over RDF data. It supports SPARQL 1.1 query and update, and its API can access remote RDF repositories in the same way as local ones. Supported formats include RDF/XML, Turtle, N-Triples, N-Quads, JSON-LD, TriG, and TriX. Storage options include a transactional in-memory store with optional disk persistence and a transactional Native Store aimed at medium-sized datasets around 100 million triples. Extensions add full-text search, RDFS inferencing, rule-based reasoning, SHACL and SPIN validation, and geospatial queries. The SDK bundles libraries, Server, Workbench, Console, and Javadoc API; Workbench includes a web interface with a SPARQL editor. Developers can use Maven artifacts or download an SDK zip or onejar. RDF4J is free under the Eclipse Distribution License, version 1.0. The latest stable release, 6.1.0, requires Java 25 or newer. The project describes its core databases as mainly intended for small to medium-sized datasets and notes third-party stores may scale further or offer additional features.
RedStore
RedStore is a free, self-hosted RDF triplestore written in C with the Redland library. It provides a built-in HTTP server and interface for loading and querying RDF data. Supported standards include SPARQL 1.0 Query, SPARQL 1.1 Protocol for RDF, SPARQL 1.1 Graph Store HTTP Protocol, and SPARQL 1.1 Service Description. The project describes support for a wide range of RDF formats, including Turtle. Storage modules can use hashes, MySQL, memory, PostgreSQL, SQLite, or Virtuoso when contexts are supported; hashes is the default. A URI can be loaded at startup, or RDF files can be sent with HTTP PUT. The /sparql endpoint works with the SPARQL Query Tool, and rdfproc supports offline operations. Redland is the only listed runtime dependency, with minimum versions for raptor2, rasqal, and redland. Installation uses configure, make, and make install. RedStore runs on Linux and macOS, offers API use, and has a Mac OS X app.
