The platform scales from individual developers to global enterprises, providing centralized reporting and policy management through axe Auditor and axe Monitor. You can track your compliance progress across thousands of pages and ensure your digital products meet WCAG and ADA requirements. Whether you are a developer, tester, or compliance officer, you get the specific tools needed to build a more inclusive digital experience for all users.

Moderne

Moderne is a continuous software modernization platform designed to help you manage large-scale code changes across thousands of repositories simultaneously. Instead of manually fixing security vulnerabilities or updating deprecated libraries one by one, you can use automated 'recipes' to search, transform, and fix your code in minutes. It leverages the OpenRewrite ecosystem to perform type-accurate abstract syntax tree (AST) transformations, ensuring your code remains functional and clean after every automated update.

You can use the platform to automate migration tasks like moving from Java 8 to 17, fixing common security flaws (SAST), and enforcing consistent coding standards across your entire organization. It is built for platform engineering and security teams at mid-to-large enterprises who need to reduce technical debt without slowing down development cycles. By centralizing code analysis and remediation, you gain full visibility into your software inventory and the power to fix issues at the source.
