vFunction
Analyses a large application's architecture to show where the coupling actually is, for teams facing a rewrite.
Highlights
- Architectural Discovery and Visualization: Utilizes AI to discover and map the architecture of applications, providing visual insights into architectural health.
- Dependency Mapping: Identifies and maps dependencies within applications to uncover complex relationships and potential areas for improvement.
- Technical Debt Analysis: Continuously identifies and analyzes architectural technical debt, offering remediation suggestions.
- Prioritization and Alerting: Prioritizes issues based on impact and alerts teams to critical areas needing attention.
- Architectural Drift Monitoring: Observes and tracks changes in application architecture over time to prevent drift from the intended design.
- Remediation and Automation: Generates actionable remediation plans and automates the resolution of technical debt.
- Integration and Exporting: Integrates with existing development tools and allows for exporting of architectural data for further analysis.

About vFunction
What it is
vFunction analyses running applications to expose their real architecture — what depends on what, where the coupling is, which parts could be separated — and tracks how that structure drifts over time. It is aimed at large, long-lived systems where the architecture in anyone's head stopped matching the code years ago.
Why it's different
The problem is real and expensive: monolith decomposition projects fail mostly because nobody actually knows the dependency structure, so teams split along organisational lines rather than real boundaries and produce a distributed system with all the coupling and none of the simplicity. Measuring the structure from the running application rather than from documentation is the right input. Where to be careful: the analysis tells you where boundaries could go, not whether the rewrite is worth doing — and the honest answer is frequently that it is not. A tool that makes decomposition look tractable can encourage a project that should not start. It is also enterprise-priced and aimed at Java and .NET estates specifically.
How people use it
It is used by architecture teams in large organisations planning modernisation, and increasingly to prevent the problem — tracking architectural drift so new coupling is visible while it is still cheap to undo. The most valuable output is usually the evidence it gives for an unpopular conversation: showing that two services teams believe are independent share a data path is worth more than any refactoring suggestion.
