Why Vale {CLI, Server, Studio, ...}?

Vale, and its ecosystem of related software and tools, offers an unmatched combination of privacy, performance, and extensibility.

Privacy

Both Vale CLI and Vale Server operate entirely offline—meaning your content is never sent to a remote server for processing.

Performance

Vale CLI, which powers both Vale Server and Vale Studio, offers unmatched performance across multiple document types.

Learn more ›

Extensibility

Vale doesn't attempt to teach you how to write; it's a tool for writers. You get to create your own rules according to your own content.

Learn more ›

Syntax- and context-aware linting

Vale has a rich understanding of many markup formats, allowing it to avoid syntax-related false positives and intelligently exclude code snippets from prose-related rules.

Learn more ›

State-of-the-art natural language processing (NLP)

Vale leverages the open-source spaCy library to allow for advanced, NLP-based rules in multiple languages, including English, Chinese, German, Russian, and Spanish.

An open-source core

All of our tools and software embrace the culture of open source—Vale, its styles, and its plugins are all open source and permissively licensed.
