Tolgee

Tolgee provides a web‑based localization environment that lets developers and translators work directly inside the application being localized. By installing its SDK and using a Chrome extension, users can press a key combination on any UI element to open an in‑context editor, add or modify strings, and capture screenshots of highlighted text without leaving the running app. The platform also supports machine‑translation services such as DeepL, Google Translate and AWS Translate, offering AI‑generated suggestions to speed up the workflow.

The system is built as a self‑hostable, open‑source service under the Apache‑2.0 license, with a free tier that requires no subscription. It integrates with code through SDKs rather than merely synchronizing external files, enabling a seamless, embedded translation experience for both development and production environments. Collaborative features allow multiple contributors to edit translations, while a translation‑memory component proposes reuse of previously entered strings.

Tolgee targets developers who need a flexible, on‑premises solution for managing multilingual content and translators who prefer a visual, in‑app editing interface. Its emphasis on in‑context editing, machine‑translation integration, and open‑source licensing distinguishes it from hosted alternatives.
