Tolgee review
A flexible localization stack with self-hosting and a dedicated Unreal Engine plugin.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tolgee is an open-source translation management and localization platform for developers, translators, and product teams. It supports web, mobile, desktop, and game workflows through SDKs, a CLI, REST API, file import and export, and integrations including Figma and Unreal Engine. Game teams can use its Unreal Engine localization plugin to push and pull localization content through Tolgee, while in-context editing, screenshots, review workflows, and translation memory help connect language work with product context.
Pricing is structured around a free plan and the paid Optimise tier. Free includes all standard localization features, automation and machine translation, all Tolgee integrations, 30,000 words, and 3 seats, with no credit card required. Optimise is listed at €133 per month when billed annually and adds an AI translator, Brand context, glossaries, AI playground, and branching. That makes the free plan a practical starting point for smaller localization projects, while teams needing the additional AI and workflow capabilities should budget for the paid tier.
Its ecosystem is broad for a developer-oriented localization tool. Integrations cover React, Angular, Vue, Svelte, Next.js, i18next, Vanilla JS, Android, iOS, Flutter, Figma, Slack, Unreal Engine, the REST API, and a Chrome extension. CLI synchronization and file import/export also support established development workflows, and self-hosted deployment gives teams control over where the localization system runs. Tolgee is a strong fit for teams that value open-source software, self-hosting, and Unreal Engine support; teams with small language volumes should consider whether the paid-tier cost is justified for advanced capabilities.
