How it works
From source code to actionable intelligence in four steps
Start fast and see the difference within weeks.
Connect your repositories
CAST plugs directly into GitHub, BitBucket, Azure DevOps, and other source code repositories to access your applications.
Semantic analysis runs
CAST deterministically analyzes source code across 450+ technologies, mapping objects, data flows, dependencies, and architectural relationships.
Dashboards and maps generated
Interactive visual blueprints, call graphs, quality grades, and risk scores are produced for both individual applications and full portfolios.
Teams and AI agents act on facts
Executives govern portfolios, developers prioritize remediation, and AI agents receive verified architectural context via MCP to transform code safely.
What it does
Deterministic intelligence for every software initiative
CAST analyzes actual source code - not guesses - to give executives, developers, and AI agents the context they need.
Application mapping
Reverse-engineer any application into an interactive visual blueprint showing code objects, data structures, dependencies, and call graphs.
Structural integrity gates
CAST Gatekeeper applies ISO 5055 rules to detect system-level flaws affecting security, resiliency, and efficiency before changes reach production.
Portfolio governance
CAST Highlight scores technical debt, cloud maturity, open source risk, and AI readiness across your entire portfolio with empirical facts.
Cloud migration analysis
Identify the best candidates for cloud migration, surface blockers, and estimate work effort so you can plan with confidence.
SBOM management
CAST SBOM Manager generates and manages software bills of materials. Available as a free download.
AI agent context
MCP server delivers architectural context to AI coding agents so they understand complex applications and make safer, more accurate changes.

Good to know
Common questions about CAST
What does deterministic software intelligence mean?+
The information is derived through semantic analysis of the actual software rather than inferred or generated probabilistically by an LLM. CAST identifies the application's real objects, dependencies, transactions, data flows, and architectural relationships.
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-enabled workflows without introducing another tool to replace.
Why can't an AI coding agent understand the application on its own?+
AI coding agents generate code effectively but struggle to understand 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 and unintended downstream impacts.
What development and modernization use cases does CAST 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.
How is CAST deployed?+
CAST supports both SaaS and on-premises deployment. The MCP server is delivered as a Docker container or Windows extension, deployable in your environment of choice.
What technologies does CAST analyze?+
CAST supports over 450 technologies, mapping code objects, data structures, dependencies, frameworks, and cross-application relationships across your portfolio.
