The OG Image Generator is a code kit that automatically creates open graph images for your website or blog. When you publish new content, it generates the thumbnail preview images that appear when links are shared on platforms like Twitter, LinkedIn, and Facebook. You get the full source code to integrate into your own projects, which means the images are generated on-demand without manual design work.

The tool works by providing pre-built templates that you can customize with Tailwind CSS. It integrates with popular frameworks like Next.js, Nuxt, and SvelteKit. The automation is handled by a system called Sartori, which triggers image generation whenever new content is published. You're not locked into a hosted service—you own the code and can modify the templates to perfectly match your brand's visual identity.

This is particularly useful for developers and content creators who manage blogs, marketing sites, or documentation. It saves the repetitive effort of manually creating social preview images for every new article or page. Marketing teams also benefit from having consistent, on-brand previews that can increase click-through rates from social shares.
