| Best use | For developers reviewing features as small changes and revisiting earlier steps. Start with a separate practice clone to learn working copies and Bookmarks; delay team adoption until compatibility with required Git tooling is checked. | 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. | 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. |
