| Best use | Ideal for a developer or small platform team that wants encrypted configuration beside code with readable Git diffs. Use it for YAML, JSON, ENV and INI files and tightly scoped CI or runtime access. It is not a replacement for dynamic secret issuance or source-system credential rotation. | 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. | Ideal for developers, data analysts, and operators who need to clean a CSV export, inspect JSON Lines, or summarize a large file from the terminal without starting a Python project. Use it for quick, repeatable file processing; concurrent transactions and advanced visual analysis still call for a database or complementary analytics tool. |
