2026. OpenCart implemented new template builder - CurlyTag



OpenCart, an open-source CMS system for online stores, has integrated a new template builder, CurlyTag (a replacement for the legacy Twig). This is a clean, modern JavaScript template engine designed with one goal in mind: to make creating, customizing, and maintaining OpenCart storefronts as simple as possible. Its advantages include a no-hassle cache, a designer-friendly syntax, and component reuse. CurlyTag is not a third-party plugin. It has access to the same layout variables, language strings, configuration values, and module output as Twig today, at no additional cost. OpenCart claims that CurlyTag will allow developers to customize your storefront faster and more affordably.
