| 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 a developer or small team whose project commands span languages, folders, and tools. It provides documented entry points that people and agents can use and review in Git. Existing scripts may be enough for a simple project; Task does not install project tools or sandbox their commands. | 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. |
