What is it?

Tolgee is a localization platform for software teams that lets developers and translators manage app strings in one web interface instead of editing .json, .po, or similar files by hand. It is positioned as a self-hostable alternative to commercial services such as Crowdin, Phrase, and Lokalise.

The main workflow is in-context translation: holding Alt/Option and clicking an element in the running app opens a dialog to edit its string, and this also works on deployed production builds. Translators can use a Chrome extension with an API key to contribute without coding. Machine translation via DeepL, Google Translate, AWS Translate, and Azure Translator is supported, along with translation memory suggestions, auto-translation for new keys, comments, activity logs, and per-translation history.

Tolgee also provides an AI translator that uses screenshots, key descriptions, and translation memory as context, and an MCP server so AI coding assistants can search keys and manage translations. A JavaScript SDK and a CLI are available for integration.
