Rosey

Created and maintained by CloudCannon, Rosey addresses one of the most frustrating challenges in multilingual web development: the tight coupling between a site's content management system or static site generator and its translation workflow.

By decoupling these two concerns, Rosey lets developers build sites with their preferred tools Eleventy, Hugo, Jekyll, Astro, Next.js, or any other static site generator without needing those tools to have built-in localization support. The translation layer lives entirely outside the site generation process.

Rosey works by scanning your built static site for markup you've tagged as translatable, extracting all the source strings into a base locale file, and then rebuilding the site for each target language by substituting translated strings from locale files.

This approach means your source content is maintained in exactly one place your site's original templates and content files and translations are managed as separate structured data files.

When content changes in the source, Rosey makes it immediately clear which translations are stale, so translators can focus on only the strings that have actually changed rather than reviewing everything from scratch.

The locale file format that Rosey produces is intentionally simple and portable. Because translations are stored as straightforward key-value pairs in JSON or YAML files, they can be easily integrated into virtually any translation workflow.

Teams working with professional translation agencies can export locale files for human translation and import the results directly. Developers comfortable with multiple languages can edit locale files manually.
