About the product
Zest Blocks is an embeddable, framework-independent drag-and-drop visual editor (block editor / page builder) for building HTML emails and web pages.
Single
<script> tag can be inserted into any application — no React setup, no build step, no external runtime dependencies.
Works with plain JavaScript, React, Vue, Angular, Laravel, WordPress, and any backend.
One editor, two outputs: email-safe HTML (table-based, inline styled — displays well in Gmail, Outlook, Apple Mail) and clean, responsive web HTML.
The visual canvas is 1:1 with the final result: what you edit is what you get.
