    Overview

    vFunction lets teams modernize large, existing applications quickly and effectively with AI.

    AI coding tools often fall short when working across complex, real world systems. vFunction provides the architecture context and guardrails they need to produce accurate, reliable changes at scale.
    It starts by analyzing how your application actually runs in production, not just the code. From there, vFunction helps you define the architecture you want, then equips your AI coding tools with precise context, specs, and prompts to modernize or rewrite your applications.

    With vFunction, you can:

    • Preserve critical business logic
    • Reduce the risk and complexity of modernization
    • Unblock development teams and speed up delivery
    • Cut licensing costs by moving to cloud-native architectures
    • Reduce costly inefficiencies in AI assisted development

    vFunction is a part of the AWS ISV tooling program and fully funded by AWS for qualified customers and system integrators. Reach out to us for more details:

    AI Insights

     Info

    Dimensions summary

    Pricing scales by application size, measured in the number of classes in one Java or .NET application. Each contract covers a single application up to a set class count. The tiers run from S at up to 2,000 classes through 3XL at up to 100,000 classes, with mid-range steps at 5,000, 20,000, 30,000, 52,500, and 75,000 classes. You pick the tier that fits your application's size. For applications above 100,000 classes, or when covering multiple applications with custom class counts, you contact vFunction for a quote.

    Top-of-mind questions for buyers

    A class is a unit of code in a Java or .NET application. Each tier caps the number of classes covered in one application. You count the classes in your application and choose the tier whose limit matches. The platform analyzes bytecode and runtime behavior to map these classes.
    Each contract covers one application up to a fixed class count. If your application exceeds that count, you move to a tier with a higher limit. For applications above 100,000 classes, you contact vFunction for a custom quote covering your class count.
    No. Each tier from S through 3XL covers a single Java or .NET application up to its class limit. To cover multiple applications, or applications with custom class counts, you use the >100,000 option and contact vFunction for a quote.
