Linkmortem, an Autopsy for Every Dead Link

Description and use

Linkmortem automatically discovers, diagnoses, and restores dead links in websites and repositories, generating fixes and pull requests.

Problem

Web content increasingly disappears, leaving many dead links in sites and repositories.

Outcome

Linkmortem identifies dead links, recovers content, and automatically patches repositories, reducing maintenance effort and preserving web memory.

Workflow

• Collect up to 150 links from site pages or repo Markdown
• Check each link to its target section
• Recover last healthy copy from Wayback Machine
• Locate content at new address and verify identity
• Generate patch with verified replacements and evidence
• Create GitHub Action PR with patch
• Archive living links that were never saved

Evidence

Linkmortem finds them and lays them to rest. Paste a website or a public GitHub repository, and it performs an autopsy on every link.

Source

It recovers the last healthy copy of each lost page from the Wayback Machine.

Source

It writes a patch with only the replacements it can prove, and the evidence behind each one. As a GitHub Action, it turns that patch into a pull request.
