7 Best Static Code Analysis Tools for 2021 (Paid & Free)

Best static code analysis tools

Developers love writing code – they have to. Otherwise, they wouldn’t have chosen their profession. But, if there is one thing that can make their lives miserable, it is an error message throwing their new applications into chaos. And nothing is more frustrating to them than not being able to track the cause of the bugs

That is why they need the seven best static code analysis tools we are about to see.

What is static code analysis?

Let’s define static code analysis:

Static code analysis – also known as Static Application Security Testing or SAST – is the process of analyzing computer software without actually running the software. Developers use static code analysis tools to find and fix vulnerabilities, bugs, and security risks in their new applications while the source code is in its ‘static’ state – meaning when it is not being run.

This process helps reduce exposure to internal and external security risks, allows developers to create applications quickly, and lets businesses see where they stand concerning compliance to industry security standards.

Note: To find out more about SAST, you can refer to “What is SAST (Static Application Security Testing)?” – This is a post that gives a comprehensive insight into the technology itself.

This is all in contrast to Dynamic Application Security Testing or DAST, where the analysis occurs while the application is running.

What makes for a tremendous static code tool?

Businesses and developers should consider the following factors when comparing and choosing static code analysis tools:

  • Low false-positive rates – a question is what volume of false positives users of a product encounter. Their tool should help them save time, not waste it chasing issues that don’t exist. Also, the tool should make it easy to manage false positives, regardless of how low the rate of occurrence, when they do (inevitably) encounter them.
  • IDE Integration – users should be able to integrate their tools into their existing developer environments. This is critical in measuring how early in the software development life cycle (SDLC) the tools can be used; the earlier it can be used, the more effective it becomes.
  • The extent of automation – they should also ask to what extent the static testing can be automated within the development environment. Incidentally, SAST has traditionally been considered one of the more manually-driven security testing methods. Any level of automation improves efficiency.
  • Detailed reporting capabilities – developers should be able to figure out where they have gone wrong quickly and then fix the issues without resorting to more research. A good tool will not only highlight errors but also provide ample documentation and training for better understanding and directly contributing to the resolution of issues.
  • The price – the price of a SAST should be worth the tool’s performance and its features. After all, why pay for any product when there is a better alternative on the market for free?

Advantages of using a static code analysis tool

We have just had a look at the seven best static code analysis tools. Let’s now see why developers and businesses should adopt these solutions:

  • With the help of SAST solutions, the development of applications becomes faster while applications become more secure and reliable.
  • Businesses have their applications up and running in the shortest amount of time; they save time and money – and release more secure code on time – all factors that help their processes become more efficient.
  • These tools help create better developers who develop code quickly and do it without making security risks or deviating from industry best practices.
  • They also don’t waste time by having to retro-fit security into old code – they do it while it is being built; they have code insights before execution.
  • SAST tools execute scans quickly when compared with dynamic analysis (DAST), for example.
  • The search for bugs and code quality maintenance is automated, which quickly eliminates human error due to manual debugging.

Static vs. Dynamic code analysis

A point that needs to be addressed is why developers prefer to choose static code analysis tools (SAST) over dynamic (DAST).

For one, SAST tools debug the code as it is being created and before it is built. This makes it quicker and easier to clean the code. They also give developers educational feedback and the chance to fix the code themselves; this can serve as hands-on training.

DAST tools, on the other hand, fix the code by giving security teams quickly delivered improvements. But, unfortunately, they are comparatively resource-intensive and require more expertise to run.

Static code analysis tools are a must

Businesses and their developers should always have static code analysis tools integrated into their development process. It is the best way to turn code into applications that contribute to business processes without creating any risk.
