| 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 that wants self-hosted website, API, DNS, and certificate checks with a status page and threshold-based alerts. It combines active checks and simple history in one service. It does not replace resource monitoring, logs, or distributed tracing. | Best for an individual developer or small team that wants backup, deployment, and scheduled-job alerts without building a notification app. It starts with one HTTP request and can be self-hosted with users and ACLs. It is not a complete incident-management or log-retention system. |
