About Microsoft Docs X-Ray
X-ray vision for people who want to know what changed—not only what the documentation says today.
Why it exists
Microsoft Learn pages evolve every day. Guidance is clarified, previews become generally available, screenshots change, and recommendations are rewritten. Once a page is updated, the previous wording is easy to miss unless you already know where its source lives and how to read Git history.
I built Microsoft Docs X-Ray to give everyone X-ray vision into that history. If you can add one letter to a domain, you can look beneath the published page, reveal the latest change, and decide whether it matters to you.
How it works
Docs X-Ray translates a supported Learn path into its public GitHub repository and Markdown path. Your browser asks GitHub for the file’s commit timeline, downloads the selected revisions, sanitizes the rendered content, and builds readable visual and raw Markdown diffs.
There is no Docs X-Ray backend in that flow. The source mapping is checked into the public project, and the comparison happens entirely in your browser.
Made for the community
This is an independent project for administrators, architects, developers, writers, and curious people who notice small documentation changes and want to understand why they matter.
Microsoft Docs X-Ray is not a Microsoft product or service. Microsoft Learn remains the canonical documentation source, and every diff links back to the original page and public repository evidence.
If a mapping is missing or wrong, open an issue on GitHub. Clear examples and community contributions are welcome.
