Toolglade’s take

Crowdin is a capable, developer-friendly TMS with one of the more generous free tiers in the category, which is why it is a default choice for many open-source projects. Its automation and integration depth are genuine strengths for continuous localization. The main friction points are that costs can climb with seats and hosted words, and that implementation and training can add meaningful overhead for larger deployments, so budget beyond the sticker price.

About Crowdin

Crowdin is a cloud localization management platform that centralizes translation of software, apps, and content with translation memory, glossaries, machine translation, and human review. It automates continuous localization through integrations with GitHub, GitLab, Figma, and CI/CD, offers a free tier popular with open-source projects, and scales via paid plans and a separate Enterprise product.

Crowdin is a translation management system (TMS) aimed primarily at product and engineering teams. It centralizes source strings from code repositories, design tools, and content systems, then coordinates machine translation, professional translators, and internal reviewers through a shared workspace with translation memory and glossaries. The platform emphasizes automation via integrations with GitHub, GitLab, Figma, and CI/CD pipelines, so new strings are continuously pushed for translation and merged back without manual file shuffling. Crowdin also offers AI-assisted translation and quality checks alongside human review workflows. Crowdin is a strong fit for teams that treat localization as an ongoing engineering process rather than a one-time project. It offers a free tier that is especially attractive to open-source projects, while paid tiers scale up seats, hosted words, and advanced integrations. There is also a separate Crowdin Enterprise offering for larger organizations.

TL;DR

Crowdin is a cloud localization management platform for software, apps, and content teams. It centralizes translation with memory, glossaries, machine translation, and human review, and automates continuous localization via GitHub, Figma, and CI/CD. A generous free tier makes it a default for open-source projects, while paid plans and a separate Enterprise product scale up. Costs grow with seats and hosted words. It fits engineering-driven localization better than quick marketing-site translation.

Frequently asked questions

Is Crowdin free for open-source projects?+

Crowdin offers a free plan that is widely used by open-source projects, with unlimited projects and strings but limits on advanced integrations, machine translation engines, and support. Larger or commercial needs generally move to paid plans.

What makes Crowdin a TMS rather than a plugin?+

Crowdin manages the full localization lifecycle: source string ingestion, translation memory, glossaries, machine and human translation, review workflows, and syncing back to code, which is broader than a display-only translation plugin.

Which integrations does Crowdin support?+

It integrates with developer and design tools including GitHub, GitLab, Figma, Google Play, and CI/CD pipelines, plus a full API for custom automation.

How does Crowdin pricing scale?+

Cost is driven by plan tier, number of hosted words, and contributor seats. Annual billing usually includes a discount, and enterprise needs move to a custom-quoted plan.

Does Crowdin include machine translation?+

Yes. Crowdin supports AI and machine translation engines to pre-fill translations, which can then be reviewed and refined by human translators, though some engines are gated to paid tiers.
