Tolgee: Open-Source, In-Context AI Localization That Cuts Dev Effort

Tolgee turns every running build into its own translation studio. Drop a three-line SDK into React, Angular, Vue, Svelte, Next.js or plain JS, hold Alt and tap any label, and an in-context editor opens so product or community linguists can tweak copy live and watch the UI refresh instantly—no JSON spelunking, no rebuilds, no developer bottlenecks.

Our new AI Translator, powered by ChatGPT and real UI screenshots, proposes context-aware sentences that read like a local wrote them; switch on auto-translation and every new key is filled the moment it lands, leaving reviewers to fine-tune tone instead of starting from scratch.

Tolgee’s lightweight CLI snaps into any CI pipeline, and you can self-host with a single Docker image or use our EU-hosted cloud—free for open-source. The project has grown to 3100 + GitHub stars, over 130 000 weekly npm downloads across its JS packages.
