Description

Tolgee is an open‑source localization platform and i18n toolkit. It enables true in‑app, in‑context translation so teams can edit strings directly in the running app—even in production. Powered by SDK integrations, machine translation, and translation memory, it streamlines the entire localization workflow. A modern alternative to Crowdin, Phrase, and Lokalise.

Features

• In‑context translation (ALT/Option + click): Open an inline editor right on your app’s UI to add or edit keys without digging through JSON/PO files.
• One‑click screenshots: Capture your screen with highlighted phrases to give translators perfect visual context.
• Translate in production via Chrome plugin: Enter an API key and start translating your deployed app—no code changes needed.
• Deep SDK integrations: First‑class app integrations (e.g., JavaScript SDK) for a seamless developer experience.
• Machine translation providers: Use DeepL, Google Translate, or AWS Translate to speed up initial drafts and repetitive work.
• Translation memory (TM): Smart suggestions with similarity %, key, and original text to keep wording consistent.
• Auto‑translation for new keys: Automatically fill new strings using TM and/or selected MT provider.
• Activity log: Track who changed, reviewed, or commented on any phrase for full accountability.
• Comments on translations: Discuss specific strings in context and capture feedback directly in the platform.
• Per‑key translation history: See how a translation evolved per language and revert or compare as needed.
• CLI tooling: Automate common tasks and streamline localization in CI/CD.
• Self‑hosting or cloud: Run via Docker on your own infrastructure or sign up for the hosted app.

Technology Stack

• Kotlin (core platform language)
• JavaScript/TypeScript SDK (front‑end integrations)
• Docker (self‑hosting & deployment)
• Chrome tooling (production translation via extension)
• RESTful APIs (project & translation management)
