Tolgee

Tolgee is an open source localization platform, positioned as an alternative to Crowdin, Phrase and Lokalise. It removes the part of translation work that wears people down, hunting through bulky JSON or PO files to change a single string.

Rather than syncing local files with a backend, Tolgee embeds into the application through its SDKs. Holding ALT and clicking an element opens a dialog where the string is edited directly, and this in-context editing keeps working in the deployed production app, where a Chrome plugin and an API key are enough for someone with no coding skills to contribute.

Around that core sit the pieces a translation workflow needs.

• One click screenshots: ALT click a string, press the camera button, and the phrase is captured highlighted in place.
• Machine translation: DeepL, Google Translate, AWS Translate and Azure Translator, chosen in settings.
• AI translator: reads the situation around a string, screenshots, key descriptions, language notes and memory matches, then reports which reading it picked.
• Translation memory: suggests earlier translations with a similarity percentage, the key and the original text.
• Auto translation: new keys are translated the moment they are created, from memory or a machine service.
• Review trail: an activity log, comments on any translation and per key history show who changed what.

The platform ships as a Docker image, with a JavaScript SDK, a CLI and integration guides for each framework. An MCP server lets AI coding assistants search keys, create translations and trigger machine translation without leaving the editor.
