| 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 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. | Best for a developer or analyst extracting text from several document formats before search or supplying selected passages to an AI agent. It provides a repeatable CLI command and Python library, while requiring review against the original. It is not intended for layout-perfect document publishing. |
