Transform COBOL to Java
with Deterministic Precision
Modernize with Confidence and Velocity
Accelerate mainframe application modernization with precision and performance at enterprise scale. CodeNavigator's deterministic engine delivers high-velocity outcomes without GenAI hallucinations, enabling functionally equivalent and numerical precise transformation for complex COBOL portfolios. Proven across Fortune 500 organizations, CodeNavigator helps IT leaders reduce modernization risk, accelerate reliable results and enable deployment flexibility on any platform--on prem, hybrid or cloud.
Reduce MIPS. Accelerate ROI.
Reduce mainframe reliance and realize ROI faster by efficiently moving legacy COBOL to cloud-ready Java, deployable to lower cost platforms.
Modernize with Confidence and Velocity
Deterministic transformation at enterprise scale. Millions of lines converted daily with guaranteed functional equivalence and numeric precision.
Move to Modern, Maintainable Java
Produce production-ready, 12-factor Java designed for scalability, resilience, and long-term maintainability.
Deploy Anywhere. No Lock-In.
Full code ownership with freedom to run anywhere.
Mission-Critical Systems Cannot Be "Almost Right."
Mission-critical systems do not tolerate "almost right." In enterprise IT, 99.9% accuracy still means defects, delays, and risk. Business leaders require legacy code transformation that is reliable, precise, and production-grade. CodeNavigator + Atlas combines deterministic models with Agentic AI to deliver functional equivalence, numeric precision, and predictable modernization outcomes. The result: higher confidence, greater velocity, and measurable value without the risks of a GenAI-only approach.

Why Choose CodeNavigator
Functional Equivalence and Numeric Precision
CodeNavigator delivers functional equivalence through deterministic, large-context COBOL analysis enriched by JCL and compiler listings. The result is Java that faithfully preserves mainframe behavior, rounding, and numeric precision without hallucination risk.
Highly Maintainable Java Output
CodeNavigator generates the highest-quality code output by producing 12 app factor Java and applying configurable transformation rules to align results with your organization's coding standards and practices.
High Velocity Transformation
CodeNavigator uses large-context analysis to enable enterprise scale, transforming millions of lines of COBOL code daily with 100% functional equivalence. This approach enables developers to test and deploy 2,000–3,000 lines of code per day—dramatically exceeding the 250–350 LOC industry standard.
Flexible Enterprise Deployment
CodeNavigator enables flexible, platform-independent modernization by supporting application deployment across hyperscalers, on-premises, or mainframe environments without lock-in.
Portfolio-Scale Modernization Support
CodeNavigator's deterministic ML platform incorporates customer-specific paradigms, concepts, & patterns through one-time configuration, enabling rapid, assured transformations powered by enterprise-proven patterns refined across Fortune 500 modernization programs.
"With CloudFrame, engineers can lower the risk of complex mainframe modernization, accelerate timelines, and reduce costs — while yielding production-ready Java."

Planning
GenAI is leveraged to create detailed HLDs and BRDs from the knowledge graph, providing overviews and insights into your existing applications. The CloudFrame AI SME provides semantic search across the entire knowledge graph, answering the questions your team needs to properly plan and execute your modernization goals.
Deterministic Transformation

Test & Validate
Because CodeNavigator's code output is automatically functionally equivalent, testing and validation is greatly accelerated, especially compared to hallucination prone GenAI-based solutions. Discover you need a code change during testing? Not a problem, you can retransform in minutes, not weeks, maintaining your project deadlines.
Deploy
