Description

NextXen Designer gives your WooCommerce store a fully interactive product customization canvas powered by Fabric.js. Customers add text, upload photos, place shapes, and browse clipart directly on a product mockup — then add their personalized design straight to the cart.

No external services. No monthly SaaS fees. Everything runs on your own server.

Free Features

Canvas & Tools

  • Canvas designer — Fabric.js-powered design canvas with a live product mockup background
  • Text tool — add text with font family, size, color, bold, italic, and alignment controls
  • Image upload — customers upload their own JPG, PNG, GIF, or WebP images (configurable max size)

  • Clipart browser — browse and insert clipart from the admin-uploaded library
  • Template browser — start from a pre-built design template
  • Canvas toolbar — undo / redo (40-step history), delete, duplicate, bring forward / send backward, and align (left, center, right)
  • Clear all — reset the canvas with a single click

Asset Libraries (Admin)

  • Font library — upload TTF, OTF, WOFF, or WOFF2 custom fonts; they become available to customers in the text tool
  • Clipart & SVG library — upload and manage SVG / PNG clipart; customers search and insert in one click

Design Canvas

  • Advanced typography — letter spacing, line height, text shadow, and text outline controls
  • QR code tool — customers generate a scannable QR code from any URL and place it on the canvas

Print & Fulfillment

Customer Experience

  • Design sharing — generate a shareable link so customers can send their design to others
  • Price modifiers — charge extra per text element, per image element, or as a base design fee

Developer & Agency

  • REST API — full CRUD REST API under nextxen-designer/v1 for headless or third-party integrations
  • White label — replace all “NextXen Designer” branding in the WordPress admin with a neutral “Product Designer” label

Upgrade to Pro

Built for Reliability

  • All output is properly escaped; all database queries use $wpdb->prepare()
  • Nonces on every AJAX request and form submission
  • Capability checks on all admin-only endpoints
  • File uploads handled entirely by WordPress’s own media_handle_upload()
  • No external CDN dependencies — Fabric.js is bundled inside the plugin
  • Design data snapshots are immutable — order records are never affected if a customer later edits or deletes their design

External Services

This plugin uses Freemius to handle license management, account registration, upgrade flows, and usage analytics. When a user opts in (consent is required before any data is sent), the following information is transmitted to Freemius servers (https://wp.freemius.com):

  • WordPress admin email address, site URL, and WordPress/PHP versions (for license and account management)
  • Plugin activation and deactivation events
  • Anonymous aggregate usage data (only when the user explicitly opts in)

No data is sent to Freemius without the user’s explicit consent. You can review and manage connected sites from your Freemius account dashboard.

FAQ

Does this work with any WooCommerce product type?

The designer works with Simple and Variable products. It adds a “Customize Product” button on the single product page.

Will my customers need to install anything?

No. The entire designer runs in the browser using JavaScript. No plugins, apps, accounts, or browser extensions are needed on the customer’s side.

Is it compatible with WooCommerce Blocks (cart and checkout blocks)?

The plugin currently uses the classic shortcode-based cart and checkout. Blocks checkout is not yet supported (declared as incompatible). It works with the Classic Cart / Classic Checkout blocks.

Can I offer the canvas on multiple sides of a product (front, back, sleeve)?

Yes — this is a Pro feature. You can define as many named surfaces as you need, each with its own mockup image and canvas dimensions.

Where are the designs stored?

Designs are stored in your WordPress database (wp_nxd_designs). A permanent, immutable snapshot is saved to wp_nxd_order_designs the moment an order is placed — so order records are never affected if a design is later edited or deleted.

Can customers save their design and come back to it later?

In the free version, designs are associated with the current browser session. In Pro, logged-in customers can save named designs to their My Account My Designs page and resume or re-order them any time.

How is the design attached to the WooCommerce order?

At checkout, the plugin snapshots the full Fabric.js canvas JSON and a JPEG thumbnail into the wp_nxd_order_designs table, linked to the WooCommerce order and line item IDs. This snapshot is completely independent of the original design record.

Can I translate the plugin?

Yes. A complete .pot file is included in the languages/ folder. You can create .po / .mo locale files with Poedit or Loco Translate. The text domain is nextxen-designer.

Is the plugin compatible with WooCommerce HPOS?

Yes. The plugin explicitly declares compatibility with WooCommerce High-Performance Order Storage (custom order tables) and uses wc_get_order() throughout — never get_post().

Do I need to run npm or any build tools?

No. Fabric.js is pre-bundled in assets/vendor/fabric.min.js. Site owners and end users never need to run any build commands.

What data does the plugin store, and can it be deleted?

The plugin creates two custom database tables (wp_nxd_designs and wp_nxd_order_designs) and one options entry (nxd_options). If you uninstall the plugin, uninstall.php removes all tables and options automatically.
