PrestaShop 9.0: A New Era for Open-Source E-Commerce

In June 2025, PrestaShop 9.0 was officially released, marking a major turning point in the evolution of the renowned open-source e-commerce platform.

With an entirely new technical foundation, a modern front-office theme, a brand-new Admin API, and numerous improvements in SEO, security, and performance, this version completely reimagines the e-commerce experience for both developers and merchants.

In this article, we present the key new features of PrestaShop 9.0 and explain why this version stands as a true paradigm shift for the future of online stores.

What is PrestaShop 9.0 and why is it important?

The engine of PrestaShop 9.0 is built on a fully updated technology stack, most notably with the move to Symfony 6.4 LTS and compatibility with PHP 8.1 to 8.4. This upgrade provides a more secure, faster, and better-adapted foundation to meet the current needs of e-commerce projects.

Benefits for developers:

• Reduced technical debt thanks to cleaner, better-structured code.
   
• Improved performance through better memory and cache management.
   
• Long-term compatibility ensured with the latest versions of PHP and Symfony.
   
• Symfony container on the front end (experimental), paving the way for headless front-office development.
  
   

This modernization makes the platform more scalable and strengthens its stability when handling high traffic loads.

The Admin API: A revolution for integrations

What are the main new features of PrestaShop 9.0?

One of the major innovations in PrestaShop 9.0 is the introduction of a complete Admin API, built on API Platform and the Symfony framework. This API-first approach radically transforms the way third-party systems (CRM, ERP, PIM, etc.) can interact with PrestaShop.

What the new API allows:

• Simplified integrations with marketing and logistics tools.
   
• Task automation (order management, stock synchronization, etc.).
   
• Support for REST, JSON-LD, and GraphQL protocols.
   
• Documented, versioned, and extensible API.
  
   

This opens up huge potential for agencies and developers who want to create custom solutions or connect PrestaShop to a wider digital ecosystem.

Hummingbird: The new front-office theme

PrestaShop 9.0 introduces Hummingbird, a new modern front-office theme developed with Bootstrap 5, TypeScript, and a modular SCSS architecture based on the BEM convention.

Key features of the Hummingbird theme:

• Mobile-first and responsive design.
   
• Optimized accessibility (keyboard navigation, ADA compliance).
   
• Improved Core Web Vitals scores.
   
• Smoother category-based navigation.
   
• Compatibility with modern image formats (WebP, AVIF).
  
   

Although Hummingbird is not yet the default theme, it represents the direction PrestaShop intends to take for its front end: modularity, performance, and accessibility.

What are PrestaShop 9.0’s SEO improvements?

Search engine optimization is at the heart of this version. PrestaShop 9.0 delivers long-awaited SEO features for online merchants.

SEO enhancements in PrestaShop 9.0:

• Customizable URLs without numeric IDs.
   
• Removal of the default language prefix in URLs.
   
• Improved canonical tags for product variants.
   
• Automatic redirects when categories or products change.
   
• Exclusion of filtered pages from indexing to avoid duplicate content.
   
• Better handling of robots.txt and sitemap.xml files.
  
   

These improvements help stores boost their search rankings while reducing indexing errors.

How does this new version improve the merchant and customer experience?

PrestaShop 9.0 significantly improves the product management interface. The focus is on ergonomics, speed, and clarity, with tools designed for large catalogs.

New product features:

• More intuitive and responsive interface.
  
   
• Bulk product editing.
  
   
• New product combination editor.
  
   
• Real-time preview during edits.
  
   
• Centralized management of prices, stock, and images.
  
   
• Better performance, even for large catalogs.
  
   

This overhaul increases e-commerce team productivity and simplifies merchants’ daily operations.

What are the back-office improvements?

The back office also gets a complete redesign, with a clearer, faster, and better-organized interface. Fully built on Symfony and Twig, it offers a smoother experience across all devices, including mobile.

Back-office enhancements:

• Unified design (header, sidebar, navigation).
   
• Improved accessibility (keyboard navigation, screen readers).
   
• Experimental dark mode.
   
• Faster load times.
   
• More powerful filters and searches.
   
• Manual creation of guest customers.
  
   

What new security and developer optimization measures are included?

PrestaShop 9.0 integrates many security and developer experience improvements:

• Targeted debug mode via cookie.
   
• Extended logging of module actions.
   
• Better protection against direct file access.
   
• Random table prefixes by default during installation.
   
• Built-in Symfony profiler.
   
• Environment-based configuration (prod/dev).

Upgrading to PrestaShop 9.0 means investing in:

• Better technical performance.
   
• Better user experience.
   
• Better SEO visibility.
