| Best use | For developers and small teams that want architecture and data-flow diagrams close to the repository and reviewable as text. Use it when relationships matter more than pixel-perfect placement; not for free-form marketing design or exact manual positioning. | Best for an individual developer or small team running a VPS, home server, or a few Docker hosts and needing a simple dashboard, history, and alerts. Its value is combining host and container metrics in a self-hosted hub. It is not a full logs-and-traces observability platform. | Best for a developer or small team that repeatedly edits GitHub Actions workflows and wants to test a job before pushing. It provides a local run log, while a final GitHub check remains necessary. It is not suitable when exact hosted-runner parity is required. |
