| Install complexity | Easy with a supported package manager; Homebrew must already be installed for this command. Official binaries, Windows, Linux, and source options are documented. | Moderate: pair both devices and share folders; APT requires official stable-v2 repository setup first | سهل — حزمة Python أو ملف CLI تنفيذي واحد |

| 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 working across two computers or a small team sharing files with trusted devices. It moves folder changes instead of repeating manual copies, while keeping device and storage choices under your control. It does not replace independent backups or collaborative editing, and devices holding the files must be reachable. | Best for an analyst, developer, or small team that needs to inspect and join large data files and rerun analysis locally. It adds reviewable SQL without database-server setup. It is not a multi-user transactional database for many small concurrent writes from separate processes. |
