i1n.ai's answer
i1n is the only localization tool with a native MCP server. Your AI coding assistant (Cursor, Claude Code, Windsurf) can internationalize a component in about 30 seconds, extracting strings, translating, and rewriting the code. On top of that, it generates TypeScript types for every translation key, so a typo like t('hera.titl') breaks at compile time, not silently in production. No other i18n tool does both of these things.
i1n.ai's answer
Most i18n tools make you choose: either a heavy enterprise platform at $120+/month or a bare translation API you have to wire up yourself. i1n is the full workflow in one command. AI translates your keys, but it's not blind automation. The dashboard lets you review what AI generated, fix the 10-15% it gets wrong, and lock those edits so they don't get overwritten. If your source text changes, it flags exactly which translations went stale. And if you're already using i18next or next-intl, Bridge Mode wraps your setup with type safety. No migration.
i1n.ai's answer
Developers and small teams building apps that need multiple languages but don't have the budget or patience for enterprise localization platforms. Typically working with React, Next.js, or similar frameworks. People who'd rather run a CLI command than manage spreadsheets of translations.
i1n.ai's answer
I kept setting up i18n in Next.js projects and dreading it every time. Not the translating part, the workflow around it. Creating JSON files for each locale, copying keys, fixing broken variables, finding missing translations in production a week later. The last time it happened I timed myself: a settings page with 200 keys across 5 languages ate most of my day. So I built the tool I wished existed.
i1n.ai's answer
TypeScript, Node.js, Commander.js, and the Model Context Protocol SDK for the CLI. Supabase (Edge Functions and Postgres) for the backend. React and Vite for the dashboard. Astro for the landing page. Polar.sh for payments.
i1n.ai's answer
i1n just launched and is in early access. No big names yet.
I've been using i1n on a Next.js project with 3 languages. The CLI is fast, one command to push and translate. The TypeScript generation is probably the best part, autocomplete on every key and compile-time errors if you typo one. The MCP integration with Cursor saved me a lot of time on repetitive internationalization work.
The dashboard could use more features (bulk editing, search/filter) and the docs are still thin in some areas. But for the price and the fact that the CLI is open source, it's hard to complain.
