What is Swimm.io?
Swimm is an Application Understanding Platform designed for engineering, product, and architecture teams grappling with complex legacy codebases. It solves the critical challenge of navigating these systems by providing accurate, always-up-to-date knowledge. With Swimm, you can confidently accelerate modernization initiatives and streamline application delivery.
Key Features
🧠 AI-Powered Code Analysis & Inventory: Swimm's AI-powered static analysis meticulously builds a comprehensive knowledge base from your code, revealing architecture and hidden logic. It then creates a living inventory of programs, modules, and dependencies, all with clear, explanatory names.
🔍 Business Logic Extraction: Uncover critical business rules buried deep within your legacy code, transforming complex logic into understandable insights. This capability helps you see precisely how your system works and identifies areas ripe for modernization or change.
🗺️ Dynamic System Mapping & Dependencies: Gain a complete, interactive overview of your codebase's architecture, including programs, modules, screens, and their intricate relationships. Swimm automatically generates diagrams with clear explanations, helping you easily trace data flows and user journeys.
📝 Automated Specification Generation: Turn deep insights into actionable plans by automatically reverse-engineering business rules into current specifications. This empowers non-technical stakeholders with immediate access to crucial documentation, fostering alignment across teams for clean, modern architecture.
Use Cases
Accelerating Application Modernization: Teams can confidently modernize complex COBOL applications by first gaining a holistic understanding of existing systems. Swimm helps you accurately map dependencies, decipher control flows, and extract business rules, allowing for precise project scoping and reduced risk.
Streamlining Legacy Code Maintenance: Maintain your existing systems with clarity and confidence. Developers can quickly visualize dependencies, understand call trees, and identify the impact of changes across the application, significantly reducing rework and knowledge bottlenecks.
Ensuring Regulatory Compliance: Monitor adherence to complex global regulations by translating current code implementations into plain English. Swimm provides clear, traceable explanations of business logic, enabling you to validate requirements against existing systems and demonstrate compliance effectively.
Unique Advantages
Swimm stands apart in its approach to application understanding, offering distinct advantages for enterprise environments:
Trustworthy AI with Deterministic Analysis: Unlike many AI solutions, Swimm combines advanced deterministic code analysis with AI to ensure every explanation is accurate and traceable to its source code, eliminating "hallucinations." This ensures predictable, reliable results for complex legacy codebases.
Always Up-to-Date and Comprehensive: Your application's context layer automatically evolves with your codebase, ensuring documentation is never outdated. Swimm performs a complete analysis of entire codebases at impressive speeds, explaining millions of lines in hours.
Enterprise-Grade Security & Scalability: Built for the most demanding environments, Swimm is SOC2 and ISO 27001 compliant, offering secure cloud and on-premise deployment options. It scales to any size, capable of handling millions of lines of code, and supports custom frameworks and codebase idiosyncrasies.
Industry-Recognized Innovation: Swimm was recognized as a Gartner Cool Vendor for 2024 in AI-Augmented Development and Testing. This acknowledgment highlights its importance for engineering leaders tackling complex legacy systems and regulatory constraints.
Conclusion
Swimm is your essential partner for transforming legacy code into a strategic asset, providing the clarity and control needed to navigate complex modernization journeys. Empower your teams with a shared, accurate understanding of your applications. Explore how Swimm can accelerate your delivery and de-risk your initiatives.
