Open Source Browser Projects
Web browsers retrieve, interpret, and display content from the internet, letting people read, communicate, work, and use online services. They handle web standards, site data, permissions, and interactive features, while shaping how users manage privacy, security, accessibility, and performance. Browser-related software can also bring web capabilities to specialized environments or enable computation directly in a browser.
Open source tools in this area include complete browsers, browser engines, extensions, and libraries for web-based features. When choosing one, consider its maturity, license, maintenance activity, supported platforms, resource requirements, security practices, and compatibility with your existing tools and workflows. These options are useful to everyday web users, developers building browser-based applications, and organizations seeking more control over their browsing environment.
