The seL4 Foundation welcomes Xcalibyte as a member. Xcalibyte's mission is to improve the quality of software by creating easy-to-use tools that help developers build and deploy reliable and secure code. Founded by world-class software experts with decades of experience in compiler optimization and software development, Xcalibyte was established in 2018 and has offices in Shenzhen, Shanghai, Beijing and Hong Kong. Xcalibyte enhances the speed and accuracy of code auditing, code evaluation, and code defect detection. We use advanced static code analysis to help reduce costs, improve productivity, and ensure software developers in China and all over the world have the proper capabilities to develop better, more reliable software. “As we are actively working with members of the seL4 Foundation, it makes perfect sense for us to be part of the organisation. Our code analysis tools are being used by community members and we are aiming to ensure they develop high quality and secure code.” Gernot
