CodeFootprint: offline file change tracker

CodeFootprint launched on the Mac App Store on June 3, 2026, as an offline-only file change tracker [devto]. The app logs each file change as a full diff, stores deletions as recoverable snapshots, and builds a chronological trace that can be exported as a JSON bundle. All data stays on the local machine; the binary never opens a socket, never contacts an API, and never requires a user account. The UI shows a simple timeline view, and a right-click menu lets you copy a change set to the clipboard for downstream tools. By keeping all data local, CodeFootprint eliminates the risk of exposing proprietary code, configuration files, or unpublished prototypes to SaaS back-ends. This approach also enables reproducible debugging by providing a deterministic change trace that can be fed into multiple AI coding assistants [devto]. The launch of CodeFootprint demonstrates that a viable product can succeed without a subscription model, challenging the assumption that continuous revenue requires cloud sync. If other toolmakers adopt a similar offline-first stance, the ecosystem could see a diversification of licensing options and a slowdown in data-harvesting practices.
