Swift Performance AI
vs
WP Rocket
Configuration
Swift Performance AI offers over 200 options, but it has the ability to automatically configure itself. Although you do have the option to adjust the settings, in most cases, you don't need to touch them.In contrast, WP Rocket has only 30+ options, but they require manual configuration. Typically, some level of expertise is required to achieve optimal results. Additionally, WP Rocket has an extensive documentation library of over 300 pages, some of which are quite long. For example Delay JavaScript Execution compatibility exclusions article

Page Caching
Page Caching
WP Rocket uses your sitemaps to locate URLs, but cache preload is not enabled by default. Cache lifespan must be set manually, and different lifespans can't be used for different pages. LSCache is not supported by WP Rocket, and you need an add-on to manage Cloudflare or Varnish cache. Additionally, a separate plugin is required to use Cloudflare APO.On the other hand, Swift Performance AI employs more advanced algorithms to identify URLs and assign priorities to them. Cache lifespan is managed automatically, and it utilizes multi-level optimization for faster cache preloading. Swift Performance AI includes built-in support for LSCache and Cloudflare, and it offers Proxy caching, which provides the same functionality as Cloudflare APO at no cost.
By using Swift Performance fragments, it's possible to load dynamic content (such as Gutenberg blocks, Elementor widgets, shortcodes, etc.) on cached pages. This allows you to utilize caching for logged-in visitors while still displaying the admin bar, loading the appropriate prices for multi-currency shops, and more.
CSS Optimization
WP Rocket provides two methods to optimize CSS: Remove Unused and Async CSS. However, both methods often require manual adjustments such as adding a CSS safelist or a fallback Critical CSS, and can be prone to bugs such as missing styles or broken pages. Additionally, WP Rocket does not create separate Critical CSS for each page by default.Swift Performance places a strong emphasis on creating reliable Critical CSS. It generates Critical CSS separately for each URL, as each page is likely to be unique, eliminating the need for manual tweaking and ensuring failsafe operation.
To provide optimized page performance for logged-in users, Swift Performance can utilize the generated Critical CSS even if logged-in caching is not enabled. This ensures that logged-in users receive the same benefits of optimized CSS as non-logged-in users.
CSS Optimization
JavaScript Optimization
On the other hand, WP Rocket's script optimization is considered outdated and requires manual tweaking. According to WP Rocket documentation, there may be up to 300 exceptions that need to be added manually.
Moreover, because WP Rocket only delays scripts until user interactions, it can sometimes lead to false positives in testing tools and frequently causes cumulative layout shift (CLS) for real users.
Image Optimization
An unoptimized image can be larger than all of your CSS files combined, which is why Swift Performance includes an unlimited, free image optimizer that can even optimize third-party and background images.It also uses a modern WebP-first approach and can resize images to provide the appropriate size for each device without requiring a CDN or JavaScript.
WP Rocket only lazyloads images without optimizing them. This may conceal the fact from testing tools that images are not optimized, but actual visitors will receive large, oversized, and unoptimized images in outdated formats.
Image Optimization
Video & Iframe Optimization
Video & Iframe Optimization
WP Rocket has the ability to lazyload iframes and videos, but it can't manage dynamically added iframes. Additionally, it can only use placeholder images for Youtube videos.Swift Performance offers more advanced optimization features. It can optimize dynamically added iframes and optimize embedded Google Maps, Youtube, and Vimeo content.
Swift Performance can also use placeholders for any iframe and has modern optimization techniques to prevent double click issues that can occur when iframes are replaced with placeholders.
Pricing
Compared to Swift Performance subscriptions, WP Rocket subscriptions are approximately 17% more expensive.There are a few differences between the two products, for instance, Swift Performance's Multi license is valid for up to 5 sites, whereas WP Rocket's Plus license is only valid for up to 3 sites.
WP Rocket's Infinite license allows for unlimited site usage, whereas Swift Performance's Developer license is limited to 100 sites. However, Swift Performance also offers an unlimited lifetime license option.

It configurates itself automatically, my site went from C to A after I installed it.
Absolutely recommended!
This is indeed the best caching and speed plugin for wordpress sites! Try it and see if I am right!
10/10 – Will buy again
However, neither of these come close to Swift’s Pro plugin’s all-in-one uniqueness, innovations and overall speeding up sites in so short period of time after you install it on the site.
