Thumbsmith is a tool for site owners and web developers who care about the details. It lets you easily add dynamic "Link preview" thumbnails to your site's pages, this way, when links to your site are shared on the internet, a nice, on-brand, image with tailored information can be shown instead of a generic image or nothing at all. Ultimately, it helps content-centric websites increase the click-through rates on their links, improve their site's sharing experience and, as a bonus, gain some awareness on where and how often of their links are shared on the web. How does it work ? In short, you provide the service with custom HTML/CSS templates, then a simple, public-facing "API" will be created for each template. This "API" will return rendered pictures of your templates dynamically based on the variables you provide via query parameters - all in a scalable, production-ready way. You don't have to manage anything else. We manage the file storage and caching, cache-invalidation and image rendering for you. Once you created and uploaded a template, you just need to "Hook up" your templates to your website via meta tags in your site's <head>. You can use your framework / environment of choice to create the URL strings, passing variables to your templates via query string parameters.
