If you work with RDF data, database capabilities affect how you query, reason over, and deploy it. Compare supported RDF formats and SPARQL support with federated queries, reasoning support, and RDF-star support for your workload. Deployment options help you consider infrastructure fit, while the free plan and paid-from price provide cost points to review. GraphDB and AllegroGraph appear first in the ranking, followed by Stardog and Fluree DB. Eclipse RDF4J is also among the early entries. Use these fields to narrow your comparison to the data formats, query patterns, and deployment needs relevant to your application.
26 RDF databases ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
