DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Longhorn, the case for Rook Ceph, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Longhorn
98.9 / 100- 8,039+ GitHub stars under Apache-2.0 as the developer-friendly CNCF distributed block storage platform
- Built-in web UI dashboard with 1-click volume creation, synchronous replication, and automated S3 backup targets
- Cuts commercial Portworx and AWS EBS io2 invoices by 95.8% ($150/mo self-hosted cluster vs $3,580/mo SaaS/cloud tolls)
When to Pick Rook Ceph
99.4 / 100- 13,691+ GitHub stars under Apache-2.0 as the CNCF graduated standard for Kubernetes storage orchestration
- Unified storage supporting RWO block volumes (RBD), RWX shared filesystems (CephFS), and S3 object storage (RGW)
- Disaggregated storage-compute architecture scales to petabytes with automated self-healing and zero data loss
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
