Last updated on Jun 10, 2026

Website Builder SDKs help developers add website creation, page editing, and drag and drop design functionality inside their own applications. Instead of building a full website builder from the ground up, teams can use a website builder SDK, embeddable website builder, or visual editor SDK to give users a branded editing experience inside a SaaS product, CMS, marketing platform, or internal tool. These SDKs are useful when a product needs users to create landing pages, microsites, web pages, templates, or full websites without leaving the platform.

This makes it useful for products that need more than one content creation workflow inside the same application. ### Developer Control and Extensibility The SDK can be installed through common JavaScript package workflows and customized through the GrapesJS core API. Developers can add custom components, configure blocks, manage assets, and extend the editor with plugins. This gives teams control over the editing experience and output structure. ### Embedded Product Fit The SDK is designed for white label embedding inside external web applications. Session based pricing, domain limits, storage limits, and support tiers make it suitable for teams that want to evaluate usage before scaling to larger customer facing deployments.
