Crowdin

What is Crowdin?

Crowdin is a localization management platform built for teams coordinating translation work across many languages and contributors. Rather than shipping raw JSON or PO files back and forth, it gives translators a dedicated editor, keeps context (screenshots, in-context previews) attached to each string, and syncs translated content back into your codebase or CMS through its API, CLI, or integrations. It's built for the workflow around translation, not just the act of translating.

Key features

• Translator-facing editor with in-context previews, comments, and version history per string
• Glossary and translation memory so terminology stays consistent across languages and projects
• Role-based workflows for managing agencies, freelance translators, and in-house reviewers separately
• Integrations with GitHub, GitLab, Figma, and CI pipelines to keep source and translated strings in sync automatically
• Machine translation pre-fill (multiple engines) as a starting point for human review, not a replacement for it

Who it's for

Teams with actual human translators or agencies in the loop, managing more than a couple of languages, who need workflow and quality control around the translation process itself. If you're just running your strings through an AI translator and shipping the output, this is more infrastructure than you need.

Pricing

Tiered subscription plans based on the number of strings and languages managed, with a limited free tier for small open-source or personal projects.
