Tolgee

Open-source i18n and translation platform

Tolgee is an open-source internationalization platform that enables in-context translation directly within applications.

It integrates machine translation from DeepL, Google, and AWS, with SDKs for React, Angular, Next.js, Vue, and Svelte. Self-hostable for data sovereignty with granular team permissions.

About Tolgee

Tolgee transforms the localization workflow by enabling in-context translation directly within running applications. Translators hold ALT or Option and click any text element to open an inline editing dialog, modifying strings in their visual context rather than through disconnected spreadsheets or translation management files. This approach ensures translations account for space constraints, visual hierarchy, and semantic context that are invisible when working with raw string files.

The platform integrates machine translation from DeepL, Google Translate, and AWS Translate to accelerate initial translation drafts and handle content updates. A robust permission system gives developers access to technical configuration while translators focus exclusively on language work without touching code. Import and export support covers all common formats including JSON, XLIFF, PO, and properties files, enabling seamless migration between localization tools.

Native SDKs for React, Angular, Next.js, Vue, and Svelte provide framework-specific integration patterns with minimal setup overhead. Self-hosting is available for organizations requiring data sovereignty, while the managed cloud option eliminates infrastructure management. The combination of developer convenience, translator productivity, and in-context editing makes Tolgee a practical choice for teams looking to reduce localization bottlenecks across global applications.
