i1n download | SourceForge.net

i1n is a localization platform for developers. A CLI pushes your translation keys and gets them back translated with AI, with variable protection and TypeScript type generation. Review and edit translations in the dashboard, mark them as manually approved, and get notified when source text changes make translations stale.
Ships with an MCP server that connects to AI coding assistants (Cursor, Claude Code, Windsurf) so your agent can internationalize components directly from the IDE.
Bridge Mode wraps existing i18next or next-intl setups with type safety, no migration needed. Open source CLI (MIT). Free tier is permanent.
