Lightning-Fast Performance
DockerCart Filter — possibly the fastest filter for OpenCart in the world.

• No OCMOD and no jQuery. Only pure, modern JavaScript (ES6+), no outdated libraries or core patches.
  
• Clean architecture. Controllers, models, and Twig templates — no magic, just transparent and maintainable code.
  
• Open source code. All code is available for audit. You always know what's happening in the system — no "black box".
  

Technologies That Stand Out

• Asynchronous AJAX filter. Instant filtering without page reloads, even on huge catalogs.
  
• Filtering by button and by event. Can be configured for filtering either by button press or by any filter change — ideal for any UX scenario.
  
• Scalability for marketplaces. Easily handles tens of thousands of products and hundreds of filters.
  
• Mobile convenience. The filter is adapted for smartphones: large elements, swipes, quick access to needed parameters.
  

Unique Competitive Advantages

• Filter-links (items): Any filter can be output as a separate SEO link — it's not only convenient for the user but also provides unique landing pages for promotion.
  
• Works only with native OpenCart tables. We don't create additional tables and don't clutter your database. All filtering, sorting, and outputs are based on standard tables, taking into account their order and structure.
  
• Sorting and output in the specified order. All filters, values, and options are displayed exactly as you configured them in the admin panel — no confusion or chaos.
  

Unique Optimization

• Manual SQL query optimization. Indexes, explain analysis, no "SELECT ".
  
• Caching at the filter and data level. Price ranges, brands, attributes are cached — separately for each currency and language.
  
• Instant cache update on changes.
  

Next-Generation SEO

• Clean, concise URLs. All filters are encoded in one parameter, without duplicates or garbage.
  
• Flexible indexing:
  - Simple filters — indexed.
  - Complex and price-based — noindex and canonical to the category.
  
• Dynamic titles and meta tags. H1 and title are formed taking into account the selected filters.
  

Why We're Better Than Competitors?

• No OCMOD, no jQuery, no extra layers.
  
• Clean, open, and secure code.
  
• SQL queries with indexes and explain.
  
• Caching at the filter level, not the entire page.
  
• Instant performance even with 100,000+ products.
  
• Easy integration and support.
  
• Works only with native OpenCart tables — no migrations!
  
• SEO links for each filter — unique landing pages.
  

Installation in 2 Minutes

• Easy installation via the standard OpenCart Extension Installer. Just upload the archive — and the filter is ready to work. No complex instructions.
  

Who Is This Filter For?

• For marketplaces where speed, scalability, and security matter.
  
• For stores that want to rank higher than competitors in search.
  
• For those who value clean architecture and transparency.
  
• For those who care about mobile users.
