GenerateBlocks is the minimal block library used to build full layouts inside Gutenberg without bloat. Container, headline, button, image, and the Pro Loop block, applied with utility-grade attributes, give editors enough to compose any marketing page. Sites running GenerateBlocks tend to load fast and stay maintainable. The share preview is the gap, since the block library does not generate per-post OG images.

SleekPixel covers that gap with a separate post-meta engine. 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. GenerateBlocks keeps composing the page body, SleekPixel writes the og:image meta tag in the document head. The two systems do not overlap, and neither one depends on the other for releases.

For sites using the GenerateBlocks Pro Loop block to render CPT archives, the underlying detail posts each get an automatic share card. Editors build the loop once, SleekPixel covers every detail URL the loop links to.

GenerateBlocks earned its position by being the smallest block library that can still build a full marketing site. The trade-off the plugin makes is that it does not try to handle every aspect of a site, just the layout and content blocks. The share preview lives outside that scope.

Without per-post OG image generation, even the most polished GenerateBlocks site shares its URLs with whatever the SEO plugin chose globally, which is usually the site logo. SleekPixel fills the gap with the same lightweight posture. The image renders once at save time, the output is a static PNG, and nothing extra fires at view time, which preserves the speed advantage GenerateBlocks delivers.

For sites that lean on the Pro Loop block for archive layouts, every detail post the loop links to gets a per-post share card with title and key fields. The block library keeps composing the page, the share preview keeps up automatically.
