Automate Broken Link Checking in CI/CD Pipelines

Automating broken link checks makes your documentation and website publishes safer. By including link verification in your CI/CD workflow, you catch 404s before they reach production.

GitHub Actions Example

Use a pre-built action like lychee-action to scan content automatically on every PR.

name: Link Check
on: [pull_request]
jobs:
  check_links:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
      - name: Lychee check
        uses: lycheeverse/lychee-action@v1
        with:
          urls: 'https://example.com'
          tol: '5'

GitLab CI Integration

Add the check to your `.gitlab-ci.yml` with a dockerized crawler, then fail the pipeline on any 404 or missing external link.

This practice is in line with continuous testing principles from Wikipedia's CI page.
