Why teams switch from Localize to i1n

Infrastructure, not a visual editor

i1n treats translations as code. Localize treats them as a visual layer. For developer teams, code-first wins.

Free tier vs $150/mo

i1n Starter is free with 200 keys and 2 languages. Localize starts at $150/mo with no free option.

Type-safe by default

i1n generates TypeScript definitions automatically. Localize has no concept of type safety.

Edge-powered AI + MCP server

i1n's AI translates 200K+ strings in parallel — plus a native MCP server that lets Cursor, Claude Code, and Windsurf internationalize entire components in seconds. Localize has no AI agent integration.
