Tolgee

Tolgee is an open-source localization platform designed for developers and teams who need to translate their applications into multiple languages efficiently. Instead of relying on separate translation files or external tools that require constant developer intervention, Tolgee allows translators and non-technical team members to modify texts directly within the live application interface. This in-context translation approach eliminates the common bottleneck of waiting for developers to update strings, because any change made in the app is instantly reflected. The platform uses AI-powered translation engines that leverage the surrounding context—such as the UI layout, adjacent text, and screenshots—to produce more accurate translations than simple string-based services. Users can also manually review and refine these translations through the web dashboard or via integrations with version control systems. Tolgee provides several integration options: it offers lightweight SDKs for JavaScript, React, Angular, Vue, and other frameworks, which enable seamless key-based translation workflows. For bulk imports or exports, the platform supports CLI commands and REST API endpoints, allowing automated syncing with continuous integration pipelines. Additionally, a Figma plugin lets designers preview translations during the design phase, reducing back-and-forth between design and development. Collaboration features include roles (admin, translator, reviewer), activity logs, and the ability to add comments on specific keys. The open-source nature means teams can self-host Tolgee on their own infrastructure for full data control, or use the cloud version for faster setup. The platform also supports file-based localization via UI import/export of JSON, YAML, XML, and other common form
