Localazy vs Locize

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.

Locize is a translation management system and localization CDN made by inweso GmbH, a small Swiss company whose founders created the i18next JavaScript library in 2011. Locize launched in 2016 as a backend that delivers translations to running apps without a redeploy, and it marked ten years in May 2026. Its core job is continuous localization: developers push keys, translators work in a web editor, and published texts reach users straight from a CDN.

The editor covers versions, history, permissions and statuses, plus an in-context editor that lets translators edit text on the live page. Translations are served through a Standard CDN (BunnyCDN) or a Pro CDN on AWS CloudFront, and machine and AI translation can use your reference language, glossary and style guide. Growth and higher plans add a review workflow, branches and tenants. Pricing is a fixed monthly plan sized by CDN downloads, words, languages and namespaces, with $5 usage blocks for extra words and downloads on higher tiers.

Locize suits JavaScript teams already on i18next, React, Next.js, Vue or Nuxt who want to change copy without shipping new builds. Lokalise and Phrase offer broader file formats, design-tool integrations and enterprise workflows, Crowdin is stronger for community and open-source translation, and Tolgee is an open-source, self-hostable option. Locize is lean and developer-first but has fewer integrations outside the web stack.

Buying tip: on every paid plan below Enterprise, going past 110% of included standard CDN downloads blocks the project, so estimate traffic carefully.
