Mosaicora

About Mosaicora

Mosaicora generates Open Graph images for every page of a site automatically, which solves the version of this problem that ordinary OG tooling does not: not making one social card, but keeping hundreds of them accurate as content changes. You design a template once, and Mosaicora fills it from each page's own content — extracting the title, subtitle and other fields from the page itself — then keeps the preview up to date as the page changes, serving the result from a CDN. That is the automatic path. There is also an API path for developers who want explicit control: POST a template id and a content object to /api/v1/images/generate and get production-ready image bytes back as JPEG, PNG or WebP, with saved templates, predictable output and CDN delivery, which suits a build-time helper that stamps an og:image URL into each page's meta tag. A free browser-based designer with ten templates lets you produce a 1200×630 PNG with no account at all, running entirely in the browser, and there are integration paths for connecting an existing site plus a checker that previews your current social card. The distinction the pricing makes is worth noting because it decides which plan you need: an image generation is creating or updating a page image from its latest content, whether triggered automatically, manually or in bulk, while serving an already-cached image is free and unmetered. The company publishes its full Polish registration details in the footer.
