Why teams switch from Localize to i1n

Copy lives in your repo

Localize translates your site as a hosted layer. i1n keeps translations as files in your repo: the product team edits them in the dashboard and engineers pull them with one command.

Free tier vs sales-quoted pricing

i1n Starter is free with 200 keys and 2 languages, and every paid plan has a public price. Localize pricing is tailored and quoted by sales.

Type-safe by default

i1n generates TypeScript definitions automatically, so a missing key fails at compile time. Localize does not generate typed keys.

Edge-powered AI + MCP server

i1n's AI translation runs in parallel, and its MCP server lets Cursor, Claude Code, and Windsurf extract, translate, and type an entire component in one session. We found no documented MCP server from Localize.
