Airlift and BerqWP are both cloud-based WordPress speed optimization plugins, which already puts them in a narrower category than most competitors. They share the same fundamental premise: move optimization work off your server and into the cloud. But the way each plugin executes that idea, and how far they take it, is where the meaningful differences appear.
This comparison is for WordPress site owners evaluating cloud optimization tools. If you have already ruled out traditional local plugins and are deciding between these two specifically, this article breaks down the practical differences honestly.
TL;DR
Both BerqWP and Airlift are cloud-based WordPress optimization plugins. Neither runs optimization on your server. The differences come down to image formats, JavaScript controls, monitoring, and automation scope.
BerqWP delivers images in AVIF with WebP as a fallback. Airlift does basic compression only with no AVIF support. BerqWP also includes responsive image sizing through a dedicated image CDN, LCP image preloading, and dimension-matched lazy loading placeholders that prevent layout shift. Airlift has none of these.
For JavaScript, BerqWP offers four execution modes (Flora, Sequential Blocking, Parallel, Sequential) plus per-script exclusion controls. Airlift’s JavaScript controls are limited and users have reported execution delays on complex sites with no clear way to resolve them without contacting support.
Airlift’s full automation including automatic cache management requires a paid plan. BerqWP automation is consistent across all paid plans with no manual steps.
BerqWP includes built-in Web Vitals Analytics showing real user data per page and device. Airlift has no equivalent. BerqWP also includes white-label on all plans. Airlift does not offer white-label.
Airlift is worth considering if you are already a BlogVault customer and want a single vendor. For everything else, BerqWP covers more of the stack with more control.

Feature Deep-Dive
1. Cloud Architecture: Both Cloud, but Different in Practice
Both plugins move optimization work off your server, which is the right starting point. But the implementation differs in ways that matter for day-to-day reliability.
BerqWP’s Photon Engine processes each page entirely on BerqWP’s own cloud infrastructure. Your server handles the original traffic; BerqWP’s cloud fetches pages, runs the full optimization pipeline, and delivers the result. No optimization work touches your hosting resources. Real-time compatibility patches for themes and plugins are applied at the cloud level, across all BerqWP sites simultaneously, without a plugin update on your end.
Airlift is built by the BlogVault team, which brings real engineering credibility. It runs a cloud-based optimization pipeline and provides one-click setup on activation. Full automation on Airlift, including automatic re-optimization and cache management, requires a paid plan. On the free tier, users have reported needing to trigger cache clears and re-optimizations manually.
If full hands-off automation is what you need, confirm which tier provides it before committing.
2. JavaScript Optimization: Control When Automation Breaks
JavaScript optimization is one of the most common sources of visual breakage on WordPress sites. Scripts load in the wrong order, interactions stop working, or animations break because a JavaScript dependency ran too early or too late.
BerqWP has two separate JavaScript controls. The Optimization Mode (set on the Dashboard) is an overall preset that includes how JavaScript is handled — Standard, Smart, Blaze, and Turbo represent increasing levels of optimization aggressiveness. On top of that, BerqWP > CSS & JavaScript > JavaScript Execution Mode gives you direct control over how scripts execute: Flora (the default, high compatibility), Sequential Blocking Execution, Parallel Execution, or Sequential Execution.
If a specific script is causing issues, the Exclude JavaScript field at BerqWP > CSS & JavaScript > Exclude JavaScript lets you target it directly. BerqWP Cloud also applies infrastructure-level compatibility patches when a theme or plugin’s scripts conflict with the selected mode.
Airlift’s JavaScript optimization is more limited. There is no equivalent set of execution modes to switch between. Users have reported JavaScript execution delays on some sites — elements not loading, interactions being slow to respond, or visible delay before the page becomes usable. When this happens, the options to diagnose and fix it are narrower.
For sites with complex JavaScript (WooCommerce, page builders, membership plugins, booking systems), having multiple execution modes and clear exclusion controls is a practical necessity, not a premium feature.
3. Image Optimization: AVIF vs. Compression Only
Image optimization is a significant gap between the two plugins.
BerqWP’s image optimization on the Cloud method is comprehensive:
- Format conversion: Images are served in AVIF to browsers that support it, WebP as a fallback, and the original format as a last resort. The decision is made per request based on the visitor’s browser. AVIF typically produces 20-30% smaller files than WebP at equal visual quality.
- Fluid Images: Images are delivered through BerqWP’s image CDN at the right size for each visitor’s device. A responsive srcset with breakpoints at 200w, 400w, 600w, 800w, 1000w, 1200w, and the original width is generated automatically. Mobile visitors get smaller files; retina displays get higher-density versions. Your original image files on the server are never modified.
- Smart lazy loading: Below-the-fold images are replaced with SVG placeholders that match the exact dimensions of the original image, preventing Cumulative Layout Shift. The real image loads when the visitor scrolls within 200px of it.
- LCP preload: BerqWP identifies the most prominent above-the-fold image on each page and adds a high-priority preload hint. This directly reduces Largest Contentful Paint time.
- Video lazy loading: YouTube embeds are replaced with a static thumbnail until the visitor clicks, removing the iframe and third-party scripts from the initial page load.
Airlift’s image optimization covers compression and some lazy loading, but does not include AVIF delivery, responsive image sizing, or LCP-targeted preloading. For image-heavy sites where image weight is a significant driver of CWV scores, this is a meaningful gap.
4. Core Web Vitals Monitoring
BerqWP includes a Web Vitals Analytics dashboard that collects real-user CWV data from your actual visitors, broken down by page and device. You can see LCP, CLS, and INP scores, identify which pages are failing Google’s thresholds, and track whether optimization changes are improving things, all from inside WordPress.
Across BerqWP’s active sites, 84.6% of 4.8 million real user sessions passed Google’s Core Web Vitals in the last 28 days, based on BerqWP’s Web Vitals Analytics data.
Airlift does not include built-in Core Web Vitals monitoring. You would rely on Google Search Console or a third-party tool to track your actual field scores. This means you are optimizing without a clear feedback loop on whether changes are working.
5. Reliability and Compatibility
BerqWP’s cloud architecture means compatibility issues with themes and plugins are handled at the infrastructure level. When a popular theme or WooCommerce update introduces a JavaScript conflict with BerqWP’s optimization, BerqWP’s team can push a patch to the cloud that takes effect immediately for all affected sites, without requiring a plugin update on your end.
Some Airlift users have reported compatibility issues including image disappearance after optimization and JavaScript execution problems that did not resolve cleanly. Addressing these typically requires contacting support or waiting for a plugin update. For agencies managing multiple client sites, unpredictable compatibility issues are a significant operational concern.
Who Should Use Which
You need reliable JavaScript optimization with clear controls
BerqWP. Multiple JavaScript Execution Mode options and clear exclusion fields give you a way to resolve script conflicts without waiting for support. Airlift’s limited JavaScript controls make debugging harder when issues arise.
You need AVIF image delivery
BerqWP. Airlift does not support AVIF. For image-heavy sites where file size directly affects LCP scores, this matters.
You want Core Web Vitals data from inside WordPress
BerqWP. Airlift has no equivalent dashboard. Without field data, you are optimizing without feedback.
You manage multiple client sites and need white-label
BerqWP. White-label is included on all plans. Airlift does not offer white-label.
You want full automation without manual cache management
BerqWP’s automation is consistent across all paid plans with no manual steps required. Confirm Airlift’s automation scope before assuming it matches.
You are already using BlogVault and want tight integration
Airlift is built by the same team. If you already use BlogVault for backups and want a single vendor relationship, that integration may be worth considering.
Looking for an Airlift Alternative?
The most common reasons users look for an Airlift alternative: JavaScript execution delays are affecting how quickly pages become interactive, image optimization is limited compared to what modern Core Web Vitals require, there is no built-in way to see whether optimization changes are improving real-user scores, or the plugin’s reliability on complex setups has required too much manual intervention.
BerqWP is the natural Airlift alternative for cloud-based WordPress optimization. Both run on cloud infrastructure and automate the optimization pipeline. BerqWP goes further: multiple JavaScript execution modes give you real control when the default configuration conflicts with your theme or plugins, AVIF image delivery and Fluid Images reduce image weight significantly more than compression alone, and the Web Vitals Analytics dashboard closes the feedback loop between optimization and real-world results.
For agencies, the white-label inclusion across all BerqWP plans removes a barrier that does not exist in Airlift.
Conclusion
Airlift is a credible cloud-based option backed by an experienced team. One-click setup and cloud processing are the right foundations, and for sites with straightforward themes and standard page structures, it may perform well.
BerqWP is the stronger choice for sites that need more: AVIF image delivery, granular JavaScript execution control, built-in Core Web Vitals monitoring, real-time compatibility patches, and white-label support for agency use. These are not niche features — they address the most common failure points in real-world WordPress optimization.
For anyone who has run into JavaScript issues, image weight problems, or score improvements that do not show up in actual user data, BerqWP’s feature set addresses those specific pain points directly.
