LiteSpeed Cache Review: Is It Really Free to Use? (2025)

Ease of Use

My rating here is 4 out of 5.

Here’s why:

• The plugin is simple to install and activate, even for beginners.
• While most settings are optimized by default, some essential features, like mobile cache, require manual intervention.
• The dashboard is user-friendly and organized, but certain features, like QUIC.cloud stats, may be irrelevant or overwhelming for users not using LiteSpeed-specific services.

LiteSpeed Cache is almost effortless to use, thanks to its quick setup and intuitive interface.

Initial Setup

LiteSpeed Cache only has one plugin, which you can easily install from the WordPress plugin repository.

On your site’s admin area, navigate to plugins > add new and search for “litespeed cache” in the search bar.

Then install and activate the plugin:

Nice! 🙂

By default, the regular caching feature (and general features) are enabled even if you’re not using a LiteSpeed server.

The only thing you may want to enable on your own is the cache mobile, which is under the “Cache” option.

It’s not enabled by default:

After activation, the plugin’s default settings are optimized for most sites.

However, you can explore additional features like image optimization and database cleaning for further enhancements.

User Interface

LiteSpeed Cache has an organized user interface, with a dedicated dashboard where you can see and manage the optimization and caching features.

It looks like this:

The biggest display here is its QUIC.cloud service usage statistics, which are only relevant to those using LiteSpeed products.

Besides that, I like that it has info here on things like:

• Cache status
• Page load time
• PageSpeed score
• Image optimization summary

Each of the items in the dashboard has buttons that will take you to the dedicated pages of these features.

For navigation, you can use the buttons in the side panel in the admin dashboard to move to the different pages of the plugin.

Best Features

I give its best features a rating of 4.3 out of 5.

Here’s why:

• The pre-configured presets cater to various skill levels, making optimization quick and accessible for all users.
• Features like QUIC.cloud CDN integration is tied to LiteSpeed servers, limiting access for users on non-LiteSpeed hosting.
• While convenient and effective, the feature requires processing through QUIC.cloud, which may involve extra steps for setup or compatibility concerns.

It stands out for its powerful and practical features like presets and image optimization, though some limitations tied to LiteSpeed servers keep it from achieving a perfect score.

Here are some notable features of LiteSpeed Cache:

1. LiteSpeed Cache Configuration Presets

I always love features that might seem small, but can actually save you a lot of time.

This is one of those features, which are simply pre-configured settings made for specific needs so users can get started without extensive technical know-how.

Here are the presets available:

Preset	Features	Who Should Use It?
Essentials	Default cache, higher TTL, browser cache	Ideal for all websites; perfect for beginners and simple setups.
Basic	Everything in Essentials, plus image optimization and mobile cache	Great for enthusiastic beginners looking for basic optimizations.
Advanced	Everything in Basic, plus Guest Mode, CSS/JS minification, Gravatar cache, and font optimization	Recommended for most websites; balances performance with compatibility.
Aggressive	Everything in Advanced, plus CSS/JS combine, critical CSS, and lazy load for iframes	Suited for websites that need strong optimizations but may require some exclusions for CSS/JS conflicts.
Extreme	Everything in Aggressive, plus lazy load for images, viewport image generation, and JS delay	Designed for power users aiming for maximum optimization; requires testing for compatibility.

To use any of the presets here, you simply need to click its “Apply Preset” button (make sure to review the applied settings).

I like these presets are they ensure optimal performance with minimal manual adjustments, nice for those who want quick results without going into every setting.

2. Image Optimization

With this feature, you won’t need to use a third-party image optimization tool.

This feature streamlines the process of reducing image sizes while maintaining quality, improving site performance, and reducing page load times.

Its key features include:

• QUIC.cloud Server Optimization
• WebP conversion
• Lossless and lossy compression
• Automatic optimization
• Backup management

To use it, simply head over to the image optimization section, request optimization for your images, and select the conversion and compression.

You will be able to review the optimization results directly in the media library, and you can see the status in the dashboard or the image optimization summary page.

3. Database Cleaner and Optimizer

Got another gem here! 💎

This database cleaner and optimizer helps maintain a fast and efficient website by removing unnecessary data and optimizing database performance.

Here are its key features:

• Post and comment cleanup
• Clean expired transient options
• Repair and optimize database tables
• Make your database use the InnoDB engine
• Customizable revision limits

If you want to use it, head over to the “Database” section, and in the “Manage” tab, click the tool that you want to use.

Yes, the boxes in there are literally the buttons for the tools, and when you click on one, it will run that tool right away.

4. QUIC.cloud CDN Integration

LiteSpeed Cache integrates seamlessly with QUIC.cloud CDN for enhanced global content delivery and optimization.

This integration ensures faster loading times by serving cached content through a distributed network.

Here are its key features:

• Global content delivery
• Dynamic content acceleration
• Automatic image optimization
• Built-in security features

Take note that you need to register your site with QUIC.cloud and enter your API key for you to use this feature.

In the CDN section, there’s a QUIC.cloud CDN setup tab where you can link to QUIC.cloud and run a CDN setup.

Reliability

For reliability, I give it a high 4.6 out of 5.

Here’s why:

• LiteSpeed Cache outperforms competitors with significantly lower execution times for both frontend (0.023 seconds) and backend (0.027 seconds).
• While updates are frequent, some features may rely heavily on them, which could cause slight disruptions if bugs arise or updates are delayed.
• The plugin is actively maintained and updated, but users relying on automatic updates must ensure compatibility with their specific setups after each release.

LiteSpeed Cache is highly reliable, delivering superior performance and regular updates to keep it ahead of competitors.

Minor concerns about update reliance don’t overshadow its consistency and speed. 🚀

Performance

I want to see how the plugin itself performs, so I run Code Profiler, and here are the results:

• Website frontend: 0.023 seconds
• Admin backend: 0.027 seconds

For comparison with its competitors (lower is better):

Feature	LiteSpeed Cache	W3 Total Cache	WP Rocket
Website Frontend	0.023 seconds	0.117 seconds	0.107 seconds
Admin Backend	0.027 seconds	0.044 seconds	0.103 seconds

As you can see, LiteSpeed Cache shows excellent performance on both the website frontend and the admin backend.

This means that LiteSpeed Cache demonstrates a balanced approach to optimizing both the frontend and backend, maintaining low execution times in both areas.

These results highlight LiteSpeed Cache as a high-performing option compared to its competitors, especially for users prioritizing speed.

The performance stats reflect real-world benefits, where faster execution times translate into better user experiences and reduced server strain.

Updates and Maintenance

As you may have guessed, LiteSpeed Cache is actively maintained, with regular updates to enhance functionality and security.

Since it’s a free plugin, you can easily find its changelog on its page on the WordPress plugin repository:

The development team frequently releases new versions, addressing bugs and introducing improvements.

Users can enable automatic updates to receive the latest versions promptly.

LiteSpeed Cache has a green flag here, with checks on:

• Active maintenance
• Frequent updates
• Changelog availability

These updates keep LiteSpeed Cache reliable, secure, and aligned with modern performance standards.

Support

For support, I give it a 3.6 out of 5.

Here’s why:

• Users can access documentation, a support forum, and a Slack community, ensuring flexibility in seeking help.
• The plugin’s documentation link points to a 404 page, and much of the content caters to developers, leaving beginners at a disadvantage.
• The WordPress.org forum is responsive and helpful, but the absence of live chat or direct customer support options might frustrate users needing immediate help.

LiteSpeed Cache offers solid support with various channels and an engaged community.

However, some usability gaps, like broken links and technical-heavy documentation, slightly dampen the experience.

Customer Service

LiteSpeed Cache provides several support options to ensure users can resolve issues quickly and efficiently.

On every page in the LiteSpeed Cache plugin, you will see the options at the bottom:

The options are:

• Documentation
• Support forum
• LiteSpeed Slack community

The support forum will bring you to the WordPress.org support forum of LiteSpeed Cache, where the community is actively engaged.

That means you can access the support forum directly from the plugin, and then ask a question there after logging in.

These support options ensure users have multiple channels to resolve their queries, which makes LiteSpeed Cache user-friendly and reliable for troubleshooting.

Documentation

LiteSpeed Cache provides detailed documentation to guide users in setting up and optimizing their websites with the plugin.

Here’s what it looks like:

The documentation is thorough and covers nearly all aspects of LiteSpeed Cache.

However, it appears to be written primarily for developers or advanced users, with its heavy focus on technical details and server-level configurations.

For beginners or less technical users, the content might feel overwhelming.

While the basic concepts are covered, the lack of simple, step-by-step guides for everyday tasks could make it less accessible for casual users.

Additionally, there’s an issue with the link provided in the WordPress plugin, which currently points to a 404 page.

Here’s where I landed:

Fortunately, I was able to find my way around, but non-technical users might get frustrated.

LiteSpeed Cache documentation is well-written and valuable for developers and advanced users, but it could benefit from more user-friendly guides for beginners.

Pricing

This one is quite short, but I give it a 4.2 out of 5.

Here’s why:

• The LiteSpeed Cache plugin itself is free and provides essential optimization tools, making it accessible to all WordPress users.
• Unlocking server-level caching or using QUIC.cloud services can incur additional costs, which may deter budget-conscious users.
• While costs depend on optional services like LiteSpeed Web Server or QUIC.cloud, users can scale their investment based on their website’s needs and growth.

LiteSpeed Cache offers excellent value with its free plugin and optional upgrades.

While advanced features may require additional expenses, the flexibility to scale makes it a great choice for both beginners and growing websites.

Cost Breakdown

LiteSpeed Cache (LSCWP) is a free, all-in-one site acceleration plugin for WordPress.

Now this is important, while the plugin itself is free, certain functionalities may require additional services that could incur costs.

Here’s a breakdown:

Item	Details	Cost
LiteSpeed Cache Plugin	Free WordPress plugin offering caching and optimization features.	Free
LiteSpeed Web Server	Required for server-level caching; available in free and paid plans.	Free Starter plan; Paid plans start at $10/month.
QUIC.cloud Services	Image optimization, CDN, and other cloud-based features.	Free tier available; Paid plans based on usage starting at $5/month.
Third-Party CDN	Optional integration for enhanced global content delivery.	Costs vary depending on the CDN provider (e.g., Cloudflare, AWS, etc.).

While LiteSpeed Cache itself is free and offers robust features, maximizing its potential may involve additional services that come with their own costs.

Final Thoughts

If you’re considering LiteSpeed Cache, start with the free plugin to see how well it fits your needs.

For advanced features like QUIC.cloud services or server-level caching, check first if they align with your website’s performance goals and budget.

Test the free tiers of these services first to gauge their impact before committing to paid plans.
