Tolgee Translator
Tolgee Translator lets development teams manage app strings, translate them with context-aware AI and machine translation, and ship multilingual releases from one workspace. JavaScript SDKs, a REST API, CLI tools, and cloud or self-hosted deployment cover the full localization loop for web and mobile products.
Unlike standalone translators that output raw text, Tolgee is built around developer workflows. SDKs auto-extract context from keys in running apps, browser plugins enable production edits, and the CLI syncs strings with your repository. You can self-host the platform, use managed cloud, or combine AI drafts with human review in the same project.
Product teams, localization managers, and engineers at SaaS and mobile companies use Tolgee when spreadsheet handoffs slow releases. Translators get glossaries, translation memory, and task tracking. Developers keep control through webhooks, Figma and Slack integrations, and an MCP server for coding assistants like Cursor and Claude Code.

In-context editing in live apps cuts the copy-paste loop between translators and developers.
Open-source core with self-hosted and cloud options fits both compliance-heavy and fast-moving teams.
AI and machine translation share the same key context, glossaries, and review workflow.
Broad integration surface: JS SDKs, CLI, REST API, Figma, Slack, and MCP for coding assistants.
Free cloud tier caps at 500 keys and 3 seats, which runs out quickly on active products.
Pricing is listed in euros and billed annually on paid tiers, which may not suit every budget cycle.
Deep setup across SDKs, CLI, and project configuration takes more engineering time than a simple MT API.

Yes. Tolgee Translator is open source and offers self-hosted on-premises deployment for organizations that need full control over data and infrastructure. Tolgee also runs a managed cloud with free and paid tiers.
What is a key in Tolgee Translator?
