Tolgee

Tolgee is an open-source localization platform for translating web and mobile applications. It provides in-context translation, AI-assisted machine translation, framework SDKs, a CLI, and a REST API. Teams can self-host the open-source platform for free via Docker or use Tolgee Cloud (app.tolgee.io). The REST API exposes projects, localization keys, translations, languages, import/export, and screenshots, authenticated with a project API key sent in the X-API-Key header.

Tolgee publishes 7 APIs on the APIs.io network, including API Keys API, Import/Export API, Keys API, and 4 more. Tagged areas include Localization, i18n, Translation, Open-Source, and Developer Tools.

Tolgee’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.
