About Crowdin

Crowdin is for teams that treat localization as an ongoing operation involving people, not just an API call. It sits in the translation management system (TMS) tradition: a central platform where source content flows in from GitHub, Figma, or a CMS, gets translated by some mix of AI, machine translation engines, professional agencies, and community contributors, passes QA checks and review, and flows back out — including over-the-air to mobile apps without an app-store release.

Its durable advantages are breadth and collaboration. The 700+ integrations cover nearly any stack a company runs, unlimited translator seats on every plan removes the per-user math most competitors impose, and features like in-context visual editing, screenshots, glossaries, and the vendor marketplace exist because real localization teams need them. Crowdin AI is included on every plan and slots into the same workflow as human translators, sharing translation memory and QA.

The tradeoff is that power reads as complexity. Small engineering teams that just want their JSON files translated on every commit will find AI-first tools like Lingo.dev or General Translation faster to adopt, and the hosted-word model gets expensive as language counts grow. Crowdin tends to win when localization involves multiple stakeholders — developers, product managers, agencies, reviewers — and the coordination itself is the problem being solved.

Pricing Plans

Estimate this tool in your stack

Crowdin bills on hosted words — source words multiplied by the number of target languages — with unlimited translator seats on every plan, which is unusual in a market that typically charges per user. The Free plan includes 60K hosted words, one private project, unlimited public projects, and Crowdin AI, and is genuinely usable for open-source work. Pro starts at $50/month (billed annually at $600) for private projects, Team at $150/month adds 100K hosted words, five managers, and role-based access, Team+ at $450/month (annual only) jumps to 500K hosted words with workflow automation and data residency, and Business is custom-priced with unlimited content, SAML SSO, and SLAs. The practical read: because pricing scales with hosted words rather than seats, Crowdin gets cheaper per person as teams grow but more expensive as language counts multiply — translating into 20 languages consumes 20x the words of one. Add-ons include the translation CDN (free up to 1M requests/10GB, then $3 per 1M requests) and a managed balance for machine translation and professional translation services.

Limitations

  • More platform than autopilot: you still configure projects, workflows, and reviews rather than delegating to an agent
  • Interface can feel complex for small teams that just want files translated
  • Key enterprise features like SSO, advanced workflows, and custom QA are gated to Team+ and Business
  • Free plan donates your translations to Crowdin's shared translation memory

Frequently Asked Questions

What are hosted words and how do they affect cost?
Hosted words are your source words multiplied by the number of target languages. A 10,000-word app translated into 5 languages consumes 50,000 hosted words. This means Crowdin's cost scales with how many languages you support — worth modeling before committing if you plan broad language coverage.
Is Crowdin free for open source?
Effectively yes. The Free plan allows unlimited public projects with unlimited translators, plus Crowdin AI, and Crowdin also runs dedicated open-source and academic license programs. The main caveat: free-plan translations are donated to Crowdin's shared translation memory.
How does Crowdin compare to AI-first tools like Lingo.dev or General Translation?
Crowdin is a management platform: it excels when humans — reviewers, agencies, community translators — are part of the loop, and its 700+ integrations cover nearly any stack. AI-first tools automate the whole pipeline with less setup but less collaboration tooling. Teams wanting human review at scale lean Crowdin; teams wanting zero-touch automation lean AI-first.
Does Crowdin use AI or human translators?
Both. Crowdin AI and machine translation engines (including DeepL and Google Translate) handle automatic translation, while the platform manages human review, professional translation orders through its vendor marketplace, and community contributions — all sharing the same translation memory and QA checks.
