Issue background
A hosted WordPress client site was previously using BlogVault’s Airlift Premium for performance optimization, which provides caching and CDN-level enhancements. However, the client requested a transition to NitroPack, a more autonomous and deeply integrated optimization platform that handles caching, compression, minification, and CDN delivery in one service.
This switch required Freshy’s team to carefully manage staging and deployment to prevent disruptions or design regressions, given the risk of cache-driven rendering or layout shifts.
Diagnosis
A staging environment was created to safely configure NitroPack before deployment to the live site. During the initial setup, several challenges arose:
- The NitroPack plugin was installed and activated, but premium settings were not accessible until the account was fully connected.
- Some media assets were missing in the staging environment, resulting in broken images.
- Default login URLs had been customized, requiring manual retrieval through Bitwarden credentials.
- NitroPack’s predefined optimization mode needed verification to ensure compatibility with the existing Divi-based theme and plugin stack.
Through collaboration between support and development teams, it was confirmed that the uploads directory was incomplete on staging. Once the directory was synced, the NitroPack configuration could proceed.
Resolution steps
- Prepared staging environment:
Cloned the live WordPress installation to a staging site hosted on WP Cloud infrastructure. Verified access credentials and login path. - Installed and configured NitroPack:
Installed the latest version of the NitroPack plugin via the WordPress dashboard. Connected the site to the client’s NitroPack account using the provided API key and secret. Enabled NitroPack’s “Standard” optimization mode as a baseline for testing. - Matched previous optimization settings:
Used a Loom video provided by the client detailing prior Airlift settings. Replicated critical performance toggles (HTML minification, image lazy loading, and cache warmup). - Resolved media discrepancies:
Synced the/uploadsdirectory from production to staging. Re-ran optimization to confirm image compression and proper rendering. - Validated site integrity:
Conducted cross-browser and mobile testing to ensure no CSS or JS conflicts. Checked for broken links and missing stylesheets post-optimization. - Client approval:
Shared staging results for review, with performance scores benchmarked via Google PageSpeed Insights. Upon confirmation, prepared for live site rollout.
Final outcome
After the successful transition, the website saw improved Google Lighthouse performance metrics, particularly in caching and render-blocking resource reduction. The shift to NitroPack also streamlined the optimization process, reducing dependency on multiple plugins and external services.
This case illustrates the importance of a structured staging process and cross-team collaboration when replacing a performance suite. The use of NitroPack, with its CDN integration and automation, provided measurable site speed improvements without sacrificing design consistency.
