About
Tolgee is a developer-friendly, open-source localization platform designed to streamline the process of making applications multilingual. Unlike traditional localization workflows that require developers to handle every text change, Tolgee enables in-context editing — translators and clients can modify text directly within the running app, eliminating the back-and-forth between spreadsheets and code. The platform offers a powerful JavaScript SDK for popular frameworks, a CLI for importing and exporting translation files, and a REST API for full programmatic control. A Figma plugin bridges the gap between design and development, allowing translation work to begin before code is even written. Tolgee's AI translation engine extracts contextual information from screenshots and key names to produce more accurate, context-aware translations — reducing manual review time significantly. Collaborative features let project leaders delegate localization tasks to clients, colleagues, or external translators through a shared, easy-to-use interface. Being open source, Tolgee can be self-hosted for full data control or used via its managed cloud offering with a free tier. It is trusted by teams ranging from startups to enterprises who need scalable multilingual support without creating recurring developer bottlenecks. Whether you're building a SaaS product, a consumer app, or an internal tool, Tolgee integrates cleanly into existing development workflows and makes going global significantly faster.
Key Features
- In-Context Translation: Translators and clients can edit text directly within the live app interface, removing the need for developers to implement every label change manually.
- AI-Powered Translations: Automatically extracts contextual information from screenshots and key names to generate accurate, context-aware AI translations at scale.
- JavaScript SDK & CLI: Integrates into any JS-based app with a dedicated SDK, and supports file import/export and key management via a powerful command-line interface.
- REST API: Full REST API access allows developers to automate translation workflows, sync localization files, and integrate Tolgee into existing CI/CD pipelines.
- Figma Plugin: Bridges design and development by allowing translation work to start directly in Figma, before code is written, speeding up the localization pipeline.
Use Cases
- Localizing a SaaS web application into multiple languages without creating recurring developer tasks for every text update.
- Delegating translation management to clients or content teams using in-context editing so they can make changes independently.
- Integrating AI-powered translation into a CI/CD pipeline via the REST API to automate multilingual content delivery.
- Collaborating with external translators on a shared platform with key management, screenshots, and translation memory.
- Starting localization work in Figma during the design phase using the Tolgee Figma plugin before development begins.
Pros
- Open Source & Self-Hostable: Tolgee can be fully self-hosted, giving teams complete control over their data and infrastructure with no vendor lock-in.
- Non-Developer Friendly: In-context editing empowers clients and non-technical team members to manage translations independently, freeing developers from routine label updates.
- Context-Aware AI Translations: AI translations leverage screenshots and key names for context, producing higher-quality results than generic machine translation tools.
- Rich Developer Tooling: SDK, CLI, REST API, and Figma plugin provide multiple integration points that fit naturally into existing development workflows.
Cons
- Initial Setup Requires Development Work: Integrating the SDK and configuring key extraction still requires developer involvement upfront, which may slow initial adoption.
- Self-Hosting Complexity: Running Tolgee on your own infrastructure requires DevOps knowledge, which may be a barrier for smaller teams without dedicated ops resources.
- Primarily JavaScript/Web Focused: While the REST API is language-agnostic, the richest SDK support is currently aimed at JavaScript-based frameworks, limiting native mobile support.
Frequently Asked Questions
Is Tolgee free to use?
Yes. Tolgee is open source and free to self-host. It also offers a managed cloud version with a free tier that requires no credit card to sign up.
How does in-context translation work?
After integrating the Tolgee SDK into your app, a translation overlay appears in the interface. Authorized users can click on any text, edit it, and save the translation — all without touching the codebase.
Can non-developers use Tolgee to manage translations?
Absolutely. Once a developer sets up the integration, clients, translators, or content managers can log in and edit translations directly through the app UI or the Tolgee platform dashboard.
What frameworks and languages does Tolgee support?
Tolgee provides a JavaScript SDK with support for popular frameworks like React, Vue, Angular, and Next.js. For other platforms, the REST API and CLI enable integration with any stack.
Does Tolgee support AI-powered translations?
Yes. Tolgee includes an AI translation feature that extracts context from screenshots and key names to deliver more accurate translations, reducing manual review and correction time.
