Application Maintenance

You have to understand your code to maintain it. CoreStory is a window into legacy code.

Legacy codebases are hard to maintain because they're hard to understand. Without sufficient documentation and clarity for how the code functions, any fix or addition is a terrible gamble. CoreStory uses AI to reverse engineer comprehensive technical and business insights from very large codebases, delivering a precise roadmap for maintaining legacy apps with confidence.

Make critical changes faster

Even with highly skilled teams, it can take months to accurately and broadly document how complex business rules and workflows are implemented in code. These insights are critical to maintaining those legacy systems.

CoreStory can process very large legacy apps in minutes, generating an intelligence model with all of the essential code insights your team requires. With all this information at your fingertips, you can confidently make updates and additions to strategy legacy apps.

Reduce regressions and hotfixes

With CoreStory, you get block-level insights to pinpoint where updates should be made, ensuring your maintenance teams are only touching the code that matters and reducing the risk of errors.

Keep mission-critical systems stable

CoreStory enables you to understand code, data, service, APIs, and architectural dependencies. You’ll have all the information needed to pinpoint exactly where in your code updates or fixes are required. More importantly, you’ll be able to identify all the dependencies possibly affected by changes so you can anticipate unintended consequences.

CoreStory helps you avoid making blind fixes or running into breaking side effects when maintaining applications. This ensures you can maintain your systems and at the same time guarantee they remain stable and safe.

Chat with your code and eliminate the guesswork

After processing your code, CoreStory generates an intelligence model that you can query with natural language.

For instance, you can ask the intelligence model where in the code a certain library is called, speeding up the onboarding of developers that are unfamiliar with the legacy stack. This significantly improves the ability of entire teams to understand all the code that needs to be maintained.

Even the oldest systems can be maintained with confidence if you have the right insights.
