| Install complexity | EASY | 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 |
| Category | Code Review, Testing | Workflow, UI | Security, Workflow |
| Best use | Best for an individual Python developer or small team that wants consistent linting, import organization, and formatting locally, in editors, and in CI. It adds reviewable rules, safe-by-default fixes, and a pinnable version. It does not replace tests, type checking, or business-logic review, and migration from Black or Flake8 should be tested on a branch. | 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. |
