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 600 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
i1n's AI translates 200K+ strings in parallel with variable masking. Localize uses basic machine translation.
