Architectural modernization powered by AI

Years of feature creep, patchwork fixes, and neglected architecture lead to bloated, brittle applications. vFunction combines architectural observability, data science, and GenAI to identify technical debt, guide LLM code assistants, and automate remediation—enabling self-healing architecture that improves quality, accelerates velocity, and ensures a cloud-ready application portfolio.

Use architectural context to guide modernization

Modernizing without architectural insight leads to risk, rework, and cost overruns.
vFunction provides the context you need—identifying modular boundaries, surfacing technical debt, and guiding GenAI assistants with architecture-aware prompts. By automating service extraction, API creation, and framework upgrades, it makes modernization repeatable and scalable. Think of it as the navigation system for your code assistants—bringing clarity and control to your cloud journey.

Identify specific refactoring opportunities

Architectural issues are the source of many software problems. vFunction pinpoints where, how, and why to address them—generating optimized prompts to guide code assistants in resolving them. Below are examples of issues vFunction helps remediate.

Domain exclusivity issues

vFunction identifies and analyzes your application and can determine logical domains and their boundaries — something that takes weeks or months in a manual event-storming exercise. It then calculates the degree to which these domains are modular and pinpoints the specific class dependencies to modularize the application.

Resource exclusivity issues

Multiple domains relying on the same resources signals increased complexity. vFunction identifies and analyzes exclusivity of different resources, such as database tables, files and more and then generates prompts to fix those dependencies using code assistants.

Dead code

vFunction identifies dead flows and obsolete code. While static analysis tools are able to identify unreachable code only, dynamic analysis in the context of domains, can identify code that is practically dead within a domain, since it never meets the logical conditions to run. Regularly reviewing and cleaning up your codebase maintains efficiency and ensures long-term maintainability.

One platform for static and dynamic code analysis

vFunction combines patented static and dynamic analysis methods to automatically identify flows, domain boundaries, dependencies and uncover technical debt. It’s the only platform focused on efficiently modernizing legacy apps by analyzing binaries statically with dynamic runtime analysis, so no potential issue goes undetected.
