Evaluating Crowdin for a product team? Pricing, migration steps and FAQ

Why teams switch from Crowdin to i1n

Product team edits, engineers sync

Product, content and ops edit copy in the i1n dashboard. Engineers pull the same keys into the repo with typed definitions. Crowdin is strongest when a community or vendors do the translating.

AI translation with enforced terminology

AI translation with brand voice and per-language terminology rules is built in, and anything that breaks a rule is flagged for review.

TypeScript type generation

i1n generates i1n.d.ts, so a missing or misspelled key fails at compile time instead of in production.

An agent loop that reaches your code

Crowdin also offers an official MCP server that exposes its platform API to AI agents. i1n's MCP server adds the code side: your agent extracts hardcoded strings from components, pushes them, translates with your glossary, and pulls type-safe definitions back in one session.
