vFunction

AI-driven modernization for large Java and .NET applications

Visit vFunction

vFunction is an AI-driven architectural modernization platform for large Java and .NET applications. It uses runtime analysis and proprietary data science to visualize application architecture, identify domain boundaries and technical debt, and generate modernization plans. The platform provides architectural context to AI coding assistants (such as Claude Code, Kiro, GitHub Copilot, AWS Transform) so they can refactor or rewrite legacy code into modular, cloud-native services. vFunction runs inside the customer's environment, behind their firewall, and is priced per application with no per-user fees. It is often funded by AWS for applications running on or moving to AWS.
