Collect Video Testimonials That Build TrustBest Website Builder SDKs
By Venkatraman Chandrasekaran
Last updated on Sep 29, 2026Website 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.
- Self hosted visual website builder for React and Next.js
- Custom React blocks with dynamic data providers and design system controls
- Customer controlled database, hosting, media storage and publishing infrastructure
Self Hosted Architecture
ChaiBuilder runs inside the customer’s Next.js application instead of placing pages and user data on vendor controlled infrastructure. The visual editor operates on the client, while authenticated actions, database access, data providers and HTML rendering remain on the customer’s server. This design supports organizations with data residency, compliance or infrastructure ownership requirements.
Developer Extensibility
Developers can create visual blocks from React components and define the properties editors are permitted to change. Server side data providers connect blocks to application data without exposing credentials to the browser. Plugins, custom actions, panels and fields allow the editing experience to be adapted to specialized website workflows.
Operational Tradeoffs
ChaiBuilder combines visual editing, Payload CMS integration, multilingual content, revisions, design tokens and AI assistance in a customer managed deployment. This gives teams control over upgrades and runtime behavior. It also makes them responsible for database backups, migrations, hosting availability, authentication, secrets and storage configuration.
- Embeddable drag-and-drop visual editor for React applications
- Custom visually editable React components with controlled properties and styling
- Dynamic external data and reusable template support
Component-Level Control
Easyblocks is designed as a framework rather than a fixed page-building product. Developers provide the React components and determine which data fields, styles, variants and child components users can modify. This structure can help product teams maintain design-system consistency while offering visual editing to nontechnical users.
Dynamic Content Architecture
External data remains controlled by the host application. Easyblocks stores references to external resources and receives current data through editor or rendering properties. Custom picker widgets and fetching functions make the framework suitable for product catalogs, reusable content records and other data-driven page templates.
Implementation Considerations
Easyblocks supplies drag-and-drop behavior, responsive fields, inline editing, history and template functionality, but it requires developers to configure the product-specific experience. Teams should also evaluate the AGPL-3.0 licence before embedding it in proprietary software or contact Easyblocks regarding custom licensing.
