Tentris
Tentris stores and queries RDF knowledge graphs using SPARQL 1.1. It keeps RDF graphs in a single compressed Hypertrie index designed to reduce memory use. For query execution, it combines adaptive planning with worst-case optimal joins, streams results, and avoids materializing intermediate results. Tentris describes its support as RDF 1.1 and SPARQL 1.1 compliant, so existing RDF data models do not need to change when switching. It is also positioned as a knowledge layer for GraphRAG, AI agents, and semantic applications requiring deterministic retrieval across connected knowledge. The Community plan is free and includes a single-core license, in-memory storage, transactions, and community support. The non-commercial license excludes production and revenue-generating use. Commercial is billed Annual, licensed per CPU core starting at 12 cores, and includes a 60-day trial license; no price is listed. Cloud is marked coming soon for Azure, AWS, and Google Cloud. Install options include Linux, macOS, Docker, and Python, with x86-64 and ARM AARCH64 listed.
