DeepL vs Localazy

DeepL is a machine translation service from DeepL, a company based in Cologne, Germany, that grew out of the Linguee online dictionary and launched its translator in 2017. It is known for output that reads more naturally and keeps nuance better than many competitors, especially for European languages, and it supports Turkish among its 30+ languages.

Users translate text in the browser, desktop and mobile apps, or whole documents such as Word, PowerPoint and PDF files while keeping their formatting. Glossaries enforce company terminology, formality settings switch between formal and informal tone in languages that distinguish them, and DeepL Write rephrases and corrects text to improve grammar and style. DeepL Voice brings real-time speech translation to conversations and meetings. Businesses integrate the DeepL API into websites, apps, CMSs and support tools, and many localization platforms such as Crowdin, Lokalise and Weglot use DeepL as a translation engine. A free tier has character and document limits, while the per-user Individual, Team and Business plans raise character and file limits and add CAT tool integration and data security guarantees.

DeepL fits professionals, translators and companies that need high-quality drafts quickly, particularly in Europe where its German base and data handling help with compliance. Its language coverage remains narrower than Google Translate, which is better for rare languages and free large-scale use. Large language models are now a serious alternative for context-aware translation.

Localazy is a localization management platform from a Czech company, built mainly for developers and small product teams who want to translate apps and websites without a heavy process. Its distinctive feature is ShareTM, a shared translation memory pooled across projects, which can automatically pre-fill common strings such as button labels and system messages in many languages.

Teams upload source files through the CLI, API or integrations, and Localazy supports common formats for Android, iOS, Flutter, JSON-based web frameworks, gettext and more. Translations can come from ShareTM, machine translation engines such as DeepL and Google, in-house contributors, community volunteers or Localazy's own professional translation service, with review workflows, glossaries and screenshots for context. Plans are tiered by the number of source keys and features, starting with a free plan for small projects and moving to paid plans for growing products.

Localazy suits indie developers, startups and open-source maintainers that want affordable localization with minimal setup. It has fewer enterprise controls and integrations than Lokalise, Phrase or Crowdin, which serve large localization teams with complex workflows, and Tolgee and Weblate are open-source alternatives for teams that prefer self-hosting. For a small app expanding into a few markets, the shared memory and machine pre-translation can noticeably reduce translation cost and effort.
