Lingo.dev CLI

Lingo.dev CLI is a free, open-source i18n CLI, that helps developers translate their apps and markdown content fast, using LLMs.

Built out of frustration with existing localization tools, Lingo.dev CLI supports all modern and industry-standard i18n frameworks, along with common file formats including JSON, XML, Localizable.xcstrings, Markdown, YAML, PO, and more.

Lingo.dev CLI is built for efficiency. It implements a versioning system that creates content fingerprints to track new or missing translatable content. It filters out untranslatable elements like numbers, dates, and code snippets. As a result, only needed content is sent to LLMs, preserving translation budget and processing time.

Lingo.dev CLI helps developers use LLM models from Anthropic or OpenAI as translation engines via API keys. That gives complete control over model selection, prompts, and model parameters.

Alternatively, Lingo.dev's specialized translation engines can be used for automatic failovers, referencing past translations, and auto-routing requests to the optimal model for each language pair and content type.

Lingo.dev CLI, is designed to help world-class developers build beautiful software products that scale to millions from day one, encapsulating translation management behind an elegant CLI tool.
