DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for LightRAG, the case for Microsoft GraphRAG, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick LightRAG
94.4 / 100- 40,167+ GitHub stars cutting GraphRAG indexing token spend by 90.9% (1,450 vs 16,000 tokens/doc)
- Incremental entity-relation graph insertion updates new documents in milliseconds without rebuilding communities
- Single-call dual-level (local + global) retrieval achieves 92ms p50 latency vs 680ms map-reduce community sweeps
When to Pick Microsoft GraphRAG
92.6 / 100- 36,358+ GitHub stars with hierarchical Leiden community detection for whole-dataset thematic questions
- 95.6% recall on global multi-document synthesis benchmarks
- Official Microsoft Research reference architecture with Azure and Parquet export pipelines
When to Self-Host in Docker / K8s
Docker / Helm HA- $0 SaaS Usage / Per-Node Tax: Run on $18-$45/mo cloud VMs or bare-metal Kubernetes nodes with flat, predictable monthly compute.
- 100% VPC Data Sovereignty: Keep production telemetry, secrets, and customer traffic inside your own private network.
- Production HA Spec Included: Deploy with pre-tuned
docker-compose.prod.yml+helm-values.prod.yamlhealthchecks and resource limits.
