Hi. My name is Andrey Sitnik and I live in Spain. I have been creating open source tools for web development since 2004.

My most famous works include PostCSS, Autoprefixer, Browserslist, Nano ID. With >300 millions downloads per day. You can likely find my work in your node_modules.

Your donation will improve web ecosystem by helping me keep the productivity in these areas:

  1. Keeping PostCSS alive (used in Tailwind CSS and webpack) and maintaining for plugins including Autoprefixer, postcss-nested, postcss-simple-vars.
  2. Promoting browsers diversity with Browserslist (used in Babel and Gatsby), browsersl.ist website, and public talks about the problem.
  3. Spreading practices to reduce JS bundle and node_modules footprint. Including creating tools like Size Limit, nano-libraries like Nano ID or Nano Stores, or an article about reducing favicon files.
  4. Creating ecosystem around oklch() to bring more vivid colors to Web. I created the first OKLCH color picker and wrote the first oklch() guide for CSS.
