Preview Environments

Every PR gets its own isolated environment — database, cache, compute, everything.

GitHub Actions

# .github/workflows/preview.yml
name: Preview

      - name: Deploy preview
        run: |
          cooper deploy \
            --env preview-pr-${{ github.event.number }} \
            --cloud aws \
            --auto-destroy-after 48h

          URL=$(cooper env url preview-pr-${{ github.event.number }})
          echo "Preview: $URL" >> $GITHUB_STEP_SUMMARY

What you get
