✨Tired of the command line? Vale now has a cross-platform desktop application that introduces a number of new features.
Hi there! I'm @jdkato, the sole developer of Vale. If you'd like to help me dedicate more time to developing, documenting, and supporting Vale, feel free to donate through the Open Collective. Any donation—big, small, one-time, or recurring—is greatly appreciated!
💥 Key Features
Support for markup: 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.
A highly customizable extension system: Vale is capable of enforcing your style—be it a standard editorial style guide or a custom in-house set of rules (such as those created by GitLab, Homebrew, Linode, CockroachDB, and Spotify).
Easy-to-install, stand-alone binaries: Unlike other tools, Vale doesn't require you to install and configure a particular programming language and its related tooling (such as Python/pip or Node.js/npm).
See the documentation for more information.
🔍 At a Glance: Vale vs.
NOTE: While all of the options listed below are open-source (CLI-based) linters for prose, their implementations and features vary significantly. And so, the "best" option will depends on your specific needs and preferences.
|Tool||Extensible||Checks||Supports Markup||Built With||License|
|Vale||Yes (via YAML)||spelling, style||Yes (Markdown, AsciiDoc, reStructuredText, HTML, XML)||Go||MIT|
|RedPen||Yes (via Java)||spelling, style||Yes (Markdown, AsciiDoc, reStructuredText, Textile, Re:VIEW, and LaTeX)||Java||Apache-2.0|
The exact definition of "Supports Markup" varies by tool but, in general, it means that the format is understood at a higher level than a regular plain-text file (for example, features like excluding code blocks from spell check).
Extensibility means that there's a built-in means of creating your own rules without modifying the original source code.
All benchmarking was performed using the open-source hyperfine tool on a MacBook Pro (2.9 GHz Intel Core i7):
