Stackable composes the page, the share layer needs its own engine
Stackable is one of the broader block libraries on top of Gutenberg, with feature blocks, hero variations, pricing tables, and a design library that gets editors from blank canvas to a finished page in a session. The block ecosystem covers most of what a marketing site needs. The share preview is not part of that scope, so most Stackable sites end up using the SEO plugin's global OG image fallback.
SleekPixel covers the share layer at the post-meta level. It hooks save_post on any post type, reads native fields plus ACF, Meta Box, and any other custom field, and renders a 1200 by 630 PNG. Stackable keeps owning the visible page, SleekPixel writes the og:image meta tag in the document head. The two layers do not share code paths, so updates ship independently.
For sites running Stackable on multiple CPTs, SleekPixel supports per-post-type templates so a blog post can use one card design while a case study CPT uses another. Editors keep composing pages with the Stackable design library, the share preview stays consistent with the brand on every URL.

Comparison
Stackable default versus SleekPixel
SEO plugin fallback
- Every Stackable post falls back to the SEO plugin's global OG image
- Block-level color and typography styles never reach the share preview
- Custom fields surfaced inside Stackable blocks stay invisible to the OG image
- Brand refresh leaves last year's share cards untouched
- Per-post Canva exports do not scale to a full Stackable site
SleekPixel
- Hooks save_post on any post type Stackable renders for
- Reads ACF, Meta Box, and native custom fields
- Self-hosted render with no per-image fees
- Template export moves between Stackable sites
- Bulk regenerate covers a full Stackable site
Features
What SleekPixel gives you for Stackable blocks
Block agnostic
Works on save_post regardless of which Stackable blocks compose the page. The image renders from post-level data, not from the block tree.
Field aware
Reads ACF, Meta Box, and native custom fields the same way Stackable dynamic content does, available inside the SleekPixel template.
Palette match
Pick the same global colors you set in the Stackable design library. The share card stays visually aligned with the rest of the site.
Use cases
Where Stackable sites benefit most
Editorial blogs
Per-post share cards with title, author, and category, while Stackable handles the article layout.
Marketing landing pages
Hero, feature, and pricing blocks compose the body. SleekPixel handles the share preview pulled from page title and campaign tag.
Resource libraries
CPT detail pages each get cards using the topic name and any field surfaced in the Stackable layout.
The bigger picture
Why Stackable sites need automated share cards
Stackable extends Gutenberg with a richer block library and a design system that keeps the visible page consistent across templates. Editors can drop a feature block or a pricing table without coding the layout, and the result on a marketing site is a polished front-end. The share preview lives outside that scope.
Stackable does not generate OG images per post, and the SEO plugin's global fallback is the only thing the share preview can fall back to. SleekPixel handles the share layer with its own template engine, sitting at the post-meta layer rather than the block tree. The result is consistent share cards on every URL, with the same level of design intent the Stackable design library brings to the visible page.
Both layers update independently, so a Stackable upgrade never breaks share images and a SleekPixel template change never touches a single block.
Questions
Common questions about SleekPixel for Stackable blocks
It runs on save_post, after Gutenberg saves. There is no Stackable block to add. The image generates server-side from saved post data.
The design library applies styles to blocks. SleekPixel reads post-level data, so design library variations in the body do not change what the share card renders.
Yes. Drop the same hex values you set as global colors into the SleekPixel template. The card stays visually aligned with the rest of the site.
SleekPixel writes only og:image and twitter:image. Title and description tags stay with your SEO plugin.
No. The render runs once at save time, the output is a static PNG. Nothing additional fires at view time.
Yes. Bulk regenerate walks every post in enabled post types and re-renders share cards with the current template.
No. SleekPixel reads post meta and writes meta tags, neither of which depends on Stackable internals.
Yes. SleekPixel supports per-post-type and per-category templates so each section of a Stackable site can have its own card design.
