RedStore review
A focused free RDF server for macOS, with core HTTP and SPARQL capabilities.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RedStore is a lightweight RDF triplestore written in C with a built-in HTTP server. It is designed for locally installed, self-hosted deployments where users need to load RDF from files or URIs, query data over HTTP, manage graphs, and select a Redland storage module. Its audience is developers and technical teams seeking a basic RDF serving layer on macOS rather than a broad enterprise knowledge-graph platform.
RedStore is open source and available as a free plan, with distribution under the GNU General Public License. Its published capabilities include SPARQL 1.0 query support, the SPARQL 1.1 Protocol for RDF, the SPARQL 1.1 Graph Store HTTP Protocol, and SPARQL 1.1 Service Description. Users can upload and delete graphs over HTTP, while storage choices include hashes, SQLite, PostgreSQL, MySQL, memory, and Virtuoso. This makes the product’s value clear for small, focused deployments that want protocol-based RDF access without a commercial plan structure.
The product keeps a narrow scope. It offers RDF loading, HTTP graph management, selectable storage, and compatibility with the rdfproc command-line tool, but its listed capabilities do not extend to reasoning, federation, or a wider integration ecosystem. The verified platform coverage is macOS, which limits its fit for teams standardizing on other operating systems. Choose RedStore when free, self-hosted RDF serving and core SPARQL protocols are the priority; choose an alternative when you need broader platform coverage, reasoning, federation, or extensive integrations.
