Shareglint is an HTTP API that turns HTML and CSS templates into Open Graph and social share images. You send a template name and field values as JSON and get back a URL to a finished PNG, JPEG, WebP or PDF, usually in about a second; templates are rendered in a real Chrome, so CSS grid, web fonts and your own design system work. It ships 153 ready-made templates, a simple layer editor, one template laid out for six sizes (OG, square, portrait, story, Pinterest, YouTube), animated GIF/MP4 from CSS animations, signed image URLs and an auto-OG tag that builds a card from a page's own title and description with no code. A screenshot API captures any public page as an image or PDF. There is also a remote MCP server for Claude, ChatGPT and Cursor, and AI template generation on paid plans. Free plan: 100 images a month without a card; paid plans from $9 for 2,000 images.
