Tentris
Tentris GmbH lists its address as Obernstraße 50, 33602 Bielefeld, Germany.
What it is
Tentris stores and queries RDF knowledge graphs and supports SPARQL 1.1. Its compressed Hypertrie index is designed to reduce memory use, while adaptive query planning and worst-case optimal joins support query execution. Results are streamed, avoiding materialized intermediate results. Tentris describes itself as RDF 1.1 and SPARQL 1.1 compliant, so an existing RDF data model does not need to change to switch. It is presented as a knowledge layer for GraphRAG, AI agents, and semantic applications that need deterministic retrieval across connected information. The free Community plan includes a single-core license, in-memory storage, transactions, standards support, and community support. Its non-commercial license covers private, academic, educational, scientific, evaluation, or research use, but excludes production and revenue-generating use; the EULA says there is no support or maintenance for this software. Commercial licensing is annual and per CPU core, starting at 12 cores, with a 60-day trial license. A cloud offering for Azure, AWS, and Google Cloud is marked coming soon. Installation options include Linux, macOS, Docker, and Python, with x86-64 and ARM AARCH64 platforms listed.
