autoprefixer-stylus is a Stylus plugin that automatically adds vendor prefixes to CSS properties, ensuring cross-browser compatibility. It leverages data from [caniuse.com](https://caniuse.com/) to determine which prefixes are necessary based on your specified browser support. By integrating seamlessly into your Stylus workflow, autoprefixer-stylus streamlines development and reduces the need to manually manage browser-specific prefixes, keeping your CSS clean and maintainable. It helps ensure consistent and modern web experiences.
The autoprefixer-stylus package saw frequent releases between 2013 and 2017, with consistent activity each year, but slowed down considerably from 2018 onwards. Only one release has occurred since 2017, in July 2019. The lack of releases in recent years suggests the package is either feature-complete, or no longer actively maintained.
Autoprefixer-stylus downloads show fluctuations. From March 2024 to February 2025, downloads ranged from 15,116 to 29,781. There's a notable surge in July 2025 (61,165 downloads), followed by a decrease in August and a further decrease in September, the current, incomplete month.
