Falls back to your default content
If unavailable
If your storefront runs JavaScript, yes. Spectare is one script tag and a few markers in your templates saying where content may vary. It does not read your product feed, touch your checkout, or need access to order data.
WooCommerce and WordPress
A plugin. Install it, paste your workspace slug, and place the sections from the block editor. Your caching plugin is not a problem: client side sections fill after the cached page loads, and server rendered ones tell the cache to skip that page automatically.
Shopify, BigCommerce and hosted platforms
The script tag goes in your theme, and the markers go in the templates you already edit. No app review, no platform specific build.
Custom and headless
Call it from your own backend and render the content yourself, so personalised markup is in the first response rather than arriving after paint.
What it never touches
Prices, stock, the basket, or the order. If Spectare is slow or unavailable, the section falls back to the default content you chose, so the page is never blank and the shopper never sees a gap.
This is one atom from the Spectare content library. Spectare assembles the right atoms for each visitor in real time, based on who they are and how they arrived.
