PrestaShop 9: A New Chapter with Symfony

PrestaShop 9 marks a major advancement for the platform. This is not just an ordinary update; it is a significant effort from the community to build a modern, reliable core. The entire system now runs on the Symfony framework. This transition was a careful plan that took years. The switch to Symfony is critical. It makes the platform faster, more secure, and more adaptable for everyone. Ultimately, PrestaShop 9 is a total overhaul. Its design makes it ready for the future and competitive in today’s e-commerce landscape.

The Symfony Switch: A Closer Look

The most significant change in PrestaShop 9 is that the entire administration area now operates on Symfony 6.4 LTS. Before, the PrestaShop team used a mix of old code and Symfony. This was complicated for developers and often caused bugs. But with this new version, the team rebuilt every single admin page. They built them to fully use Symfony and Twig templating.

As a result, developers can now work with a single, consistent framework. This consistency simplifies creating new modules and makes fixing issues much easier. The platform can also use Symfony’s strong security features. It benefits from the support of a large developer community.

In addition, this change allowed the project to remove a lot of outdated code. For example, the team has permanently removed features like the old XML API and the confusing product form. In their place is a cleaner system that is simpler to maintain. The platform also now supports newer versions of PHP (8.1–8.4). This is a huge benefit. These new PHP versions bring significant performance boosts and better error handling.

They also include Just-In-Time (JIT) compilation. This can make your store run much faster. In summary, the move to Symfony is all about making the platform more dependable, more powerful, and easier to expand.

New Features for Store Owners

While the biggest changes are “under the hood,” the admin panel itself offers a much better user experience. The interface has a more modern look, and all pages now feel consistent. You won’t see that frustrating mix of old and new interfaces anymore. This consistency makes managing your store a lot smoother and reduces the time you need to train new staff members.

For developers, one of the best new tools is the Admin API. This new API provides a modern way for other systems to communicate with your store. It’s built on a framework called API Platform, which makes connecting with things like your inventory system, customer management software, or a mobile app simple. For example, it’s now very easy to automatically update prices or sync your stock with your warehouse management system.

You could even create a custom mobile app for your store. Then you can have it pull all product and order data directly from this API. In fact, this new API is what makes headless commerce a reality. It lets you use PrestaShop for its back-end. Meanwhile, you can create a totally custom front-end with modern frameworks like React or Vue.js.

Why This Is Great for Everyone

These technical updates provide real benefits for both store owners and developers. For store owners, the platform is much faster. The updated code and PHP compatibility mean your pages will load quickly. Quick loading is crucial for keeping customers happy and getting more sales. Also, PrestaShop 9 now supports new image formats like WebP and AVIF. These images are much smaller. This speeds up your site even more without reducing quality. A faster site can also improve your Core Web Vitals score. That score is a key factor for good SEO.

The SEO features have also been refined. The platform creates cleaner, shorter URLs by default. This makes it easier for search engines to understand your site. For developers, the benefits are huge. The full Symfony architecture gives them a consistent, well-documented environment.

This makes building modules and themes easier and more enjoyable. With the new Admin API, they can build better, more powerful integrations. They can also meet today’s demanding business needs. All in all, PrestaShop 9 is a massive improvement. It’s a modern, future-proof platform.

Should You Move from PrestaShop 8.1 to 9.0? A Complete Feature Comparison

With the release of PrestaShop 9.0, the platform is moving toward a more modern, performance-oriented, and developer-friendly future. However, as with any major update, merchants and developers are left with an important question: Is now the right time to migrate from PrestaShop 8.1?

In this blog, we’ll explore the key differences between PrestaShop 8.1 and 9.0. From performance upgrades to developer tools, we’ll cover everything you need to know to make an informed decision about your store’s future.

Symfony Framework Upgrade: From 4.4 to 6.4

To begin with, one of the most significant changes in PrestaShop 9.0 is the upgrade of the Symfony framework from version 4.4 to Symfony 6.4, the latest long-term support (LTS) release. This transition ensures better stability, security, and access to modern development tools.

Symfony 6.4 will be maintained with bug fixes through November 2026 and security patches until November 2027, ensuring long-term stability for evolving projects. By comparison, Symfony 4.4—used in PrestaShop 8.1—has already reached the end of its support life. Therefore, PrestaShop 9.0 becomes the smarter choice for long-term projects.

PHP Compatibility and Performance Enhancements

In addition, PrestaShop 9.0 introduces support for PHP 8.1, 8.2, and 8.3. This allows merchants to benefit from improved performance, better memory handling, and modern PHP features.

Unlike PrestaShop 8.1, which stopped at PHP 8.1, the new version embraces the latest PHP releases, representing a major step forward. As a result, PrestaShop 9.0 is better aligned with modern PHP standards and development practices. However, keep in mind that older hosting environments and custom code may require updates to ensure compatibility.

Modern API Platform for Headless Commerce

Furthermore, PrestaShop 9.0 brings a brand-new API system based on API Platform v3, dramatically improving how it interacts with external applications.

This makes it ideal for headless commerce architectures, mobile app integrations, and third-party services. In contrast, PrestaShop 8.1 relied on a legacy API, which lacked the flexibility and scalability modern developers expect. As a result, the new API system opens up a world of opportunities for automation and integration.

PrestaShop 9 debuts a completely reimagined Admin API, built using API Platform—a cutting-edge PHP framework known for its flexibility and power. This innovation marks a significant leap toward creating a more open, extensible, and developer-focused PrestaShop environment.

Here’s what the new Admin API offers:

  • Simplified integration with external platforms such as ERPs, CRMs, and marketing tools.
  • Automation-ready architecture that helps reduce manual store management and boosts operational efficiency.
  • RESTful structure with JSON formatting, ensuring ease of use for developers accustomed to modern API standards.
  • Future-ready modularity, allowing the system to grow and adapt with community and business demands.

It’s worth noting that the Admin API is still evolving. While the core framework is already in place, additional features and endpoints are being actively developed.

Key Hook Updates in PrestaShop 9

 PrestaShop 9 retains most of the widely used hooks from version 8 to ensure module and theme compatibility. Common front-office hooks like displayHeader, displayFooter, displayHome, and displayProductButtons remain supported. In the back office, important hooks such as displayBackOfficeHeader, displayAdminOrderMain, and displayAdminProductsExtra are still available for extending core functionality.

Alongside these, PrestaShop 9 introduces modern Symfony-based hooks like actionSymfonyResponse, actionAfterCartSave, and actionProductFormBuilderModifier. These offer a cleaner, event-driven approach to customisation and are part of the platform’s move toward a more modular, scalable structure.

Redesigned Back Office Using Symfony and Twig

Another significant improvement is the full revamp of the back office, now built with Symfony and Twig for a more modern and maintainable structure. This results in a more intuitive, mobile-friendly, and user-centred admin experience.

For store owners, the redesigned layout means easier navigation and improved productivity. For developers, the shift supports cleaner templating and reduces legacy code dependencies. On the other hand, PrestaShop 8.1 retains a more traditional interface, which may now feel outdated in comparison.

Developer-Focused Improvements

Additionally, PrestaShop 9.0 has replaced several outdated libraries used in previous versions. For example:

  • Guzzle HTTP Client → Symfony HTTP Client 
  • SwiftMailer → Symfony Mailer 

These updates result in a more secure, efficient, and future-proof module and email handling.

Moreover, the login system has been modernised. Legacy hooks have been removed, and a new actionBackOfficeLoginForm hook has been introduced, offering cleaner and more customizable authentication flows.

Transition Toward Twig Templates

Importantly, PrestaShop 9.0 also makes a bold move toward full Twig integration, gradually replacing the legacy Smarty engine. Twig is now widely used in both front and back offices, offering more readable, modular, and reusable templates.

For theme developers, this is a significant improvement. In contrast, PrestaShop 8.1’s reliance on Smarty limits flexibility and long-term maintainability.

Should You Upgrade to PrestaShop 9.0?

PrestaShop 9.0 brings major improvements—but before upgrading, make sure your store is ready to handle the change. If your themes, modules, and hosting environment are compatible—or can be easily updated—then migrating can bring notable performance and UX benefits.

Alternatively, if your current store depends heavily on legacy plugins or complex custom code, it might be wiser to wait until broader module support becomes available. Testing in a staging environment is highly recommended before committing to a full upgrade.

Migration Tips for Store Owners

Before making the switch, follow these best practices:

  • Backup your entire store, including the database and any custom files.
  • Test the upgrade in a staging environment first to avoid disrupting your live store.
  • Verify compatibility for all third-party themes and modules.
  • Monitor community feedback for bug reports and migration issues.
  • Conduct thorough testing, especially checkout, payment, and product display areas. 

Final Thoughts

PrestaShop 9.0 marks a major leap toward a modern, secure, and scalable e-commerce platform. From faster performance and updated frameworks to a cleaner developer experience, it brings meaningful benefits for merchants and developers alike.

In conclusion, while migration requires effort and planning, the long-term gains make it a worthwhile investment. Whether you’re a seasoned PrestaShop user or planning your first store, now is an excellent time to explore what version 9.0 can do for your business.
