Open-source web builder framework for no-code HTML templates
Free web builder framework for creating HTML templates without coding. Drag-and-drop interface with blocks, style manager, and asset management for websites, newsletters, and mobile apps.
GrapesJS is a web builder framework designed to accelerate template creation for websites, newsletters, and mobile apps. Originally built for CMS integration, it enables developers to embed a visual editor that empowers non-technical users to build dynamic templates through an intuitive drag-and-drop interface.
The framework provides a complete visual editing environment with block-based composition, a style manager for CSS customization, layer management for component hierarchy, and integrated asset management. Built-in code viewing lets users inspect and export clean HTML/CSS. Local and remote storage options ensure templates persist across sessions.
With TypeScript at its core and a robust plugin ecosystem, GrapesJS adapts to diverse use cases. Official plugins extend functionality for forms, flexbox layouts, custom fonts, and specialized builders like MJML for responsive emails. A React wrapper enables declarative UI customization. The framework outputs standard HTML/CSS structures that integrate seamlessly with existing template systems, making it ideal for developers building content management platforms, marketing tools, or any application requiring user-friendly template editing.
When teams consider GrapesJS, these hosted platforms usually appear on the same shortlist.
