Overview

Tolgee brings application localization into a shared workflow without requiring code changes for each translation. Translators can edit text in context, while developers connect projects through frameworks, SDKs and an API. Translation memory, glossary management, context screenshots and role permissions support consistency and coordination as projects grow.

Teams can choose SaaS or self-hosting. Self-hosted customers retain control of their infrastructure, and Tolgee says it cannot access their projects, accounts or logs. That control comes with responsibility for running the deployment; SaaS is the more direct fit for teams that prefer a managed option.

Key features

The in-context editor lets translators work within the application rather than switching to a separate view. Context screenshots add visual reference, which can help clarify where a string appears. Together, they address a common software-localization problem: translating text without losing sight of its use.

Tolgee’s AI Translator uses context from its native JavaScript SDKs, including in-context dialogs, to inform translations. Tolgee says customer data is not used to train AI models and that selected LLM providers say API-submitted data is not used for training. Those statements may matter to teams considering AI-assisted work, though they do not replace a team’s own assessment of its data requirements.

Listed integrations span React, Angular, Vue, Svelte, Next.js, i18next, Flutter, Slack, Figma and Unreal Engine, alongside a REST API. Supported formats include JSON, XLIFF, gettext PO, Apple strings, Android XML, Flutter ARB, CSV and XLSX. This breadth gives teams several paths to connect application work and existing translation files, rather than tying localization to a single framework.

Tolgee states that it is ISO 27001 certified and complies with the EU General Data Protection Regulation. For SaaS, it says databases, file storage and backups are encrypted with AES-256, and network traffic with HTTPS/TLS. These protections and self-hosting controls are relevant for teams weighing how localization data is handled.

Pricing

The Free plan costs 0.00 EUR per free and includes 30,000 words, 3 seats, standard localization features, automation and machine translation. It is a useful starting point for a small project, but the word and seat ceilings make it a limited fit for larger teams or growing translation volume.

Translate costs 58.00 EUR per year, billed annually, and includes unlimited seats, 400,000 MT credits and standard localization features. Its lower price than the other listed paid tiers makes it the entry paid option for teams that need more seats and credits than Free allows.

Optimise costs 133.00 EUR per month, billed annually, with unlimited seats and 400,000 MT credits. Manage costs 373.00 EUR per year, billed annually, and includes the same stated allowances: unlimited seats, 400,000 MT credits and standard localization features. These price and term differences make it important to compare the plan terms directly before choosing; the stated inclusions alone do not establish what distinguishes their intended use.

Enterprise has custom pricing and includes premium support, SSO, a dedicated Slack channel, an account manager, team training and prioritized feature requests. It is the fit for teams that need those support and administration provisions. On-Premises also has custom pricing, with monthly or annual licensing tailored to customer needs; it includes self-hosting, advanced features and support. Choose it when infrastructure control is a requirement rather than a preference.

Platforms

Tolgee supports Android, iOS, web, API, extensions and self-hosted use. It is designed for web applications and can also be used with mobile and desktop applications; the platform options and integrations make it relevant to teams localizing across application environments.

Who it's for

Tolgee is best suited to software teams that want developers and translators working around the same application context, especially teams using its listed web frameworks or mobile integrations. The free plan can serve a small project, while paid plans remove the stated seat cap and provide 400,000 MT credits. Organizations that need infrastructure control can consider self-hosting; those needing premium support or SSO have an Enterprise option.

It is less compelling for teams whose work is not application localization, or for small projects that would quickly exceed 30,000 words or need more than three Free seats. In those cases, the price and plan terms should be weighed against the project’s actual scale and deployment needs.

Pros and cons

Pro: In-context editing and context screenshots keep translation tied to the application, helping translators understand where strings appear.
Pro: Framework, API and file-format support gives software teams multiple ways to connect projects and existing localization assets.
Pro: SaaS and self-hosted options let teams choose between managed use and infrastructure control.
Con: Free is capped at 30,000 words and 3 seats, which can constrain a project as its volume or team expands.
Con: Enterprise and On-Premises use custom pricing, so teams needing their support or deployment provisions must seek a tailored price.
Con: The listed Translate, Optimise and Manage prices use different terms, and the stated inclusions do not clearly explain the distinctions between those tiers.

Alternatives

Crowdin is another freemium option with a free plan and free trial, and it supports Android, iOS, Linux, macOS, Windows, web and API. Choose it for that stated platform range; its free-plan limits are not established here.

locize may suit teams whose needs align with its quantified free allowance: 2,000 words, 2 languages, 5 namespaces, 1 user and 100K standard CDN downloads per month. That is a much smaller stated word and seat allowance than Tolgee Free, so compare the project’s scale before deciding.

OneSky is an alternative with freemium pricing and listed AI-driven quality estimation and multi-agent translation offerings.

Weblate is worth considering for teams looking for a listed hosted-string plan: Premium Cloud 10k costs 47.00 EUR per month and includes 10,000 hosted strings with unlimited languages, projects and components. It also supports Linux and self-hosting.

Live Link Face is a free iOS and Android app.

Transglot has a Free plan with 100,000 words to start, then 10,000 per month, plus 1 project, 14 target languages and 3 seats. Its stated free allowance makes it an option to compare for teams prioritizing a larger word allocation.

Localazy offers a Free plan with 200 source keys and unlimited seats and languages, which may fit teams whose project can be measured against that source-key cap.

Playglot is a free web option.

Verdict

Choose Tolgee if your team localizes software and values in-context editing, broad integration routes and the choice between SaaS and self-hosting. Its strongest case is keeping translation close to application development; its main drawback is that the free plan is small, while higher-tier and self-hosted choices can require substantial or custom pricing. Teams outside software localization, or those whose budgets and project size do not suit those limits, should compare alternatives.
