Inside the product
From portfolio to line of code
Four products that answer the questions slowing you down.
CAST Imaging
Reverse engineers an entire application into an interactive visual blueprint, so anyone can understand architecture and structural flaws without reading code.
CAST Highlight
Governs the whole portfolio with empirical facts: technical debt, cloud maturity, open source risks, and AI readiness across hundreds of applications.
CAST Gatekeeper
A structural integrity gate that applies ISO 5055 rules to catch system-level flaws in security, resiliency, and efficiency before production.
AI agents with real context
An MCP server hands AI agents the application's true architecture, call paths, and dependencies, delivered as a Docker container or Windows extension.
CAST SBOM Manager
Free to download. Manages your software bill of materials and controls open source security and license risk.
Cloud and green software insights
Identifies best migration candidates, flags cloud blockers, and surfaces green software remediation opportunities.
Why change
Slow software is usually invisible software
Most delays come from not knowing what a change will touch.
The old way
- ×Weeks of manual discovery before anyone touches a legacy application
- ×AI coding agents guess at structure and create rework and downstream breakage
- ×Technical debt gets discussed with opinions instead of facts
- ×Cloud migrations stall because blockers surface mid-project, not upfront
The CAST way
- +Semantic analysis turns source code into maps, dashboards, and call graphs in days
- +AI agents receive a factual map of objects, dependencies, and data flows via MCP
- +Technical debt is measured, prioritized, and tracked with empirical grades
- +Cloud maturity and blockers are identified before the migration starts
The flow
From repositories to answers in three steps
Start fast and see the difference within weeks.
Connect your repositories
CAST plugs directly into GitHub, BitBucket, and Azure DevOps, on-premises or in the cloud.
Analyze the code semantically
A deterministic engine maps code objects, data structures, dependencies, frameworks, and cross-application relationships across 450+ technologies.
Act on the intelligence
Execives, developers, and AI agents navigate dashboards, maps, and call graphs to prioritize debt, clear cloud blockers, and ship changes with less risk.

Answers
Questions teams ask before speeding up
Why can't an AI coding agent understand our application on its own?+
AI agents generate code well but struggle with large, complex applications from source files alone. Important relationships span multiple technologies, databases, repositories, and applications. CAST gives the agent a factual map of these relationships, reducing blind spots, incorrect assumptions, and unintended downstream impacts.
What does deterministic software intelligence mean?+
The information comes from semantic analysis of the actual software, not from probabilistic LLM inference. CAST identifies the application's real objects, dependencies, transactions, data flows, and architectural relationships, so AI agents can ground their work in verified facts.
Does CAST replace our existing AI coding tools?+
No. CAST complements the AI tools you have already selected. It supplies deterministic application context to MCP-compatible agents and development tools, improving your existing AI workflows without adding another agent.
Which modernization use cases does this support?+
Understanding unfamiliar applications, extracting business rules, change-impact analysis, generating documentation and tests, remediating technical debt, removing cloud blockers, identifying microservice candidates, replacing frameworks or databases, and transforming legacy applications.
