Manage app translations with in-context editing, AI translation, and collaborative tools. Self-hostable and free to start.
Tolgee is an open-source localization platform that lets teams translate apps without turning every text change into a developer task. The core idea is in-context editing: non-developers can click directly on text inside the running app to edit translations, so clients, translators, or colleagues can make changes without filing tickets.
The AI translator uses visual and contextual information extracted from each UI element to produce more accurate results than generic machine translation. This cuts back-and-forth with human translators for routine strings. It's a meaningful step up from tools like LibreTranslate that handle translation without that UI context.
Teams can add translation keys directly from the app, get auto-translations immediately, and optionally run a review step before release. Files can be imported and exported through a UI or REST API. There's also a Figma plugin for design-side localization work.
Tolgee supports all major JavaScript frameworks and integrates into CI/CD pipelines, making it practical for teams that deploy frequently. If you're comparing options, it's worth looking at Weblate or Crowdin to see how the self-hosted and cloud-hosted models differ.
The free tier includes unlimited projects, 500 keys, 10,000 machine translation credits, and 3 seats. No card required.
