(A Dev Tool Story)", "summary": "A developer created CodeFootprint, a Mac app that automatically records every change to text and code files in real time. The tool allows users to export a structured trace file of their change history, enabling them to identify exactly when and how files were modified by AI tools or other processes. The app operates entirely offline with no account or cloud storage, ensuring sensitive work remains on the user's machine.", "body_md": "Picture this: you have been coding for four hours straight. Three AI tools are open. Your terminal is running scripts. Your editor has unsaved changes. You step away for coffee.\n\nWhen you come back, something is broken. A file has different content than you expected. Another file is missing entirely.\n\nWhat happened? You have no idea.\n\nThis is the reality of modern development. Multiple tools touch your files. Things change fast. And when something goes wrong, you are left reconstructing history from nothing.\n\n[CodeFootprint](https://apps.apple.com/app/codefootprint/id6741222848) is a Mac app that gives you that history automatically.\n\nSelect a folder. It records every change to your text and code files in real time:\n\nHere is where it gets interesting for AI tool users. You can export your change history as a structured trace file and hand it to your next AI tool.\n\nInstead of: \"I think something broke around 2pm, maybe in the config file?\"\n\nYou get: \"Here is every change that happened in the last 4 hours. The config file was modified at 2:17pm by an AI tool. Here is exactly what changed.\"\n\nThat is the difference between guessing and knowing.\n\nNo account. No cloud. No data leaves your Mac. A file change tracker sees your most sensitive work — it should be trustworthy by design.\n\nMore convenience. More protection. More peace of mind.", "url": "https://wpnews.pro/news/what-happened-to-my-project-in-the-last-4-hours-a-dev-tool-story", "canonical_source": "https://dev.to/huaian666/what-happened-to-my-project-in-the-last-4-hours-a-dev-tool-story-1d5c", "published_at": "2026-06-03 05:32:14+00:00", "updated_at": "2026-06-03 05:42:16.536865+00:00", "lang": "en", "topics": ["ai-tools", "ai-products"], "entities": ["CodeFootprint"], "alternates": {"html": "https://wpnews.pro/news/what-happened-to-my-project-in-the-last-4-hours-a-dev-tool-story", "markdown": "https://wpnews.pro/news/what-happened-to-my-project-in-the-last-4-hours-a-dev-tool-story.md", "text": "https://wpnews.pro/news/what-happened-to-my-project-in-the-last-4-hours-a-dev-tool-story.txt", "jsonld": "https://wpnews.pro/news/what-happened-to-my-project-in-the-last-4-hours-a-dev-tool-story.jsonld"}}
