What is it?
Localess is a translation management tool and content management system that lets teams manage and translate website or app content into multiple languages. Translations can be edited in real time, and Google Translate can be used to speed up the translation work. Publishing changes takes effect immediately, so the application does not need to be rebuilt.
On the content side, Localess lets you define the shape of your content with schematics, add validation rules, and create hierarchical content. It also provides user management with granular permissions, plus import and export for moving or backing up data. Generated data is served through an API that can be called from any kind of application.
The project is built on Firebase products: Authentication, Storage, Firestore, Functions and Hosting. Published content is cached through a Google CDN. The project also includes a migration API for moving spaces from a Firebase-hosted instance to a self-hosted install.
