Focus
Finding maintainability issues, security flaws, and code smells without running the program
Focus
Identifying runtime issues such as performance bottlenecks, memory leaks, and logic flaws
Output
Warnings and reports about potential flaws or risky patterns
Output
The program’s actual runtime behavior with logs, traces, and performance metrics
Performance overhead
None for system performance, since it doesn’t execute the code and is only used in the development process
However, there can be larger developmental overheads to consider if you’re analyzing a larger codebase.
Performance overhead
High system performance overhead, as it runs alongside or within the application in a real or simulated environment
Casos de uso
Detecting coding-standard violations, many security vulnerabilities, and maintainability issues
Casos de uso
Catching problems that only surface with real input and environment conditions
Static code analysis, which Qodana helps automate for teams in their CI/CD pipeline, is valuable throughout the entire development lifecycle. While it is particularly beneficial during the early stages of development – when catching errors and security gaps costs the least in terms of time, money, and resources – it also plays an integral role in maintaining larger codebases that can have hundreds of commits a day.
By integrating static analysis directly into your CI/CD pipeline, your team can ensure every commit is automatically vetted for coding-standard errors. This helps you maintain code quality at scale and prevent regressions.
Dynamic code analysis, on the other hand, evaluates how your code behaves in real-world scenarios or controlled test environments.
It comes into play once the application is runnable and needs testing under real conditions.
This helps you and your team spot concurrency pitfalls, memory leaks, performance bottlenecks, and security flaws that only become apparent when the code runs.
As an example, suppose you are developing a web application.
Using a static analysis tool like Qodana, you can detect a potential SQL injection vulnerability by inspecting the code without ever running it. Qodana would flag any unsafe concatenation of user inputs, highlighting high-risk security issues before they reach production.
With dynamic analysis, you would first run the application in a real or simulated environment and discover that user sessions aren't being terminated properly under specific conditions.
Relying solely on static analysis leaves gaps that dynamic analysis can fill. Both methods are powerful independently, but together, they provide a more complete picture of your codebase’s health, performance, and scalability. Try Qodana and experience automated static analysis in action!

At JetBrains, we built Qodana to enhance static code analysis. Here’s how Qodana stands out:
Thorough code insights
Qodana goes beyond the basics of identifying code smells by enforcing coding standards and providing real-time insights. It’s like having a senior developer constantly reviewing your work, highlighting issues before they escalate.
Effortless integration
Qodana integrates easily with JetBrains IDEs and any CI/CD tool, including Jenkins, GitHub Actions, GitLab, and TeamCity. Whether you’re working locally or as part of a team, Qodana fits right into your existing processes.
Customizable rulesets
You can create custom inspection profiles using YAML configuration files to define which inspections to enable or disable, specify paths or scopes for analysis, and set severity levels to mitigate unnecessary alerts. With Qodana’s FlexInspect feature, you can also create custom code inspections.
Clear, actionable reports
Qodana’s reports are easy to understand and act on. They provide clear, prioritized feedback that you can implement immediately.
