Crowdin vs Locize

Crowdin is a localization management platform founded in Ukraine in 2009 and now headquartered in Estonia. It is used by software companies, game studios and a long list of well-known open-source projects to translate apps, websites, documentation and help centers, and it offers both a standard cloud product and Crowdin Enterprise for larger organizations.

The platform supports more than a hundred file formats and syncs source strings automatically from GitHub, GitLab, Bitbucket and CI pipelines, from design tools like Figma, and from CMSs and help desks through a marketplace of over 600 apps. Translators work in an editor with translation memory, glossaries, screenshots, in-context preview, QA checks and machine translation from engines such as DeepL and Google, plus AI translation with your own prompts. Crowdsourcing features let volunteers suggest and vote on translations. Pricing combines hosted words and seats, and Crowdin is free for qualifying open-source projects.

Crowdin suits teams with many file types, many integrations or a community that wants to help translate. Its interface can feel dense, and hosted word limits need watching as content grows. Lokalise is the main commercial rival with a cleaner UI for product teams, Phrase is strong in enterprise and agency workflows, and open-source alternatives such as Weblate and Tolgee can be self-hosted. For website-only translation without code, Weglot is simpler.

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.
