From our inception, the jQuery Foundation has been about much more than just jQuery. We strive to provide a home for open source projects that are essential to, and support our vision of, making the web accessible to everyone. Check out a sampling of what we provide for these projects and our philosophy around governance, budgets, trademarks and more. If your project is interested in joining this growing list of projects important to the entire JS ecosystem, feel free to reach out any time.
