Every web product eventually gets the same feature request: "can users customize this?" A poster, a banner, a social graphic, a product card. Historically, answering yes meant integrating a heavyweight design tool, paying per seat, or building a canvas engine from scratch. Ezyreka is our answer to that problem: a full Canva-style design editor you can embed in any web app with a single script tag.
Ezyreka is a free, open-source (MIT), embeddable JavaScript library from Bookklik Technologies. No frameworks. No runtime dependencies. One script tag. It runs with its built-in UI, or as a headless canvas engine if you'd rather build your own interface on top.
What you get out of the box
Ezyreka is a complete design environment, not a drawing toy:
- Canvas engine with a DOM overlay for handles, snapping, and guides.
- Elements: text, images, shapes, lines, and icons, with full transforms, snapping, and inline text editing.
- Editable charts (data and style), multi-page documents, and 32 editable templates to start from.
- A real editor UX: layers panel, undo/redo, copy/paste, zoom and pan, context menu, and keyboard shortcuts.
- Export: PNG, JPEG, and JSON project files, plus themes, headless mode, and a customizable UI.
- Extensibility: custom element types, renderers, chart types, sidebar panels, and community plugins.
Getting started
Declarative: one div, one script
<div
id="app"
data-ezr-editor
data-ezr-width="1080"
data-ezr-height="1080"
data-ezr-name="My design"
></div>
<script src="https://unpkg.com/@bookklik/ezyreka/dist/ezyreka.umd.js"></script>
Size the container with CSS (for example, #app { width: 100vw; height: 100vh; }) and you have a working design editor on the page.
Programmatic: full control
const { Editor } = Ezyreka; // UMD global
const editor = new Editor({
target: '#app',
width: 1080,
height: 1080,
name: 'Untitled design'
});
editor.on('ready', () => {
editor.addText({ text: 'Hello Ezyreka', fontSize: 96, fontWeight: 800 });
editor.addElement({ type: 'rect', x: 340, y: 620, w: 400, h: 110, radius: 55 });
});
Using a bundler? Run npm install @bookklik/ezyreka and import { Editor } from '@bookklik/ezyreka'. Plain HTML, React, and Vue integrations are in the examples folder.
Headless when you need it
The built-in UI is optional. Drive the canvas engine directly to build your own branded experience, with your own sidebars, toolbars, and design system, while Ezyreka handles the hard parts: hit testing, transforms, snapping, rendering, and export.
Where it fits
- SaaS products letting users customize graphics, cards, and marketing assets in-app.
- E-commerce platforms offering product banner and thumbnail design.
- Internal tools and print workflows that need a canvas editor without vendor lock-in.
Ezyreka runs in all modern evergreen browsers (Chrome, Edge, Firefox, Safari), using HTML5 Canvas 2D, Path2D, ResizeObserver, contenteditable, and pointer events.
