How To Choose a Code Visualization Tool

As you're shortlisting, trialing, and selecting code visualization tools, consider the following:

  • What problem are you trying to solve - Start by identifying the code visualization feature gap you're trying to fill to clarify the features and functionality the tool needs to provide.
  • Who will need to use it - To evaluate cost and requirements, consider who'll be using the platform and how many licenses you'll need. You'll need to evaluate if it'll just be the data analytics team, or the whole organization that will require access. When that's clear, it's worth considering if you're prioritizing ease of use for all, or speed for your technical power users.
  • What other tools it needs to work with - Clarify what tools you're replacing, what tools are staying, and the tools you'll need to integrate with. This could include your existing coding tools, various data sources, and your overall tech stack. You might also need to decide if the tools will need to integrate together, or alternatively, if you can replace multiple tools with one consolidated code visualization tool.
  • What outcomes are important - Consider the result that the tool needs to deliver to be considered a success. Think about what capability you want to gain, or what you want to improve, and how you will be measuring success. You could compare code visualization tool features until you’re blue in the face, but if you aren’t thinking about the outcomes you want to drive, you could be wasting a lot of valuable time.
  • How it would work within your organization - Consider the solutions alongside your workflows and delivery methodology. Evaluate what's working well, and the areas that are causing issues that need to be addressed. Remember every business is different — don’t assume that because a tool is popular that it'll work in your organization.

The cheapest options include open-source tools like CodeFlower or Gource which are free to use. On the higher end, tools like Polyspace or Understand can be more expensive, potentially costing hundreds of dollars per user per month, depending on the features included in the package.

Are there any free tool options?

Yes, there are free code visualization tools available. Open-source tools like CodeFlower and Gource can be used without any cost. Keep in mind, though, that while these tools are free, they may not offer the same range of features or the level of support that you’d get with a paid tool.

What do you think?

Absolutely, discovering the right code visualization tool is an ongoing process and there might be effective tools out there that I haven't included in this list. I encourage readers to share their own experiences and recommendations. If there's a tool you think is worthwhile and could be a great addition to this list, please feel free to mention it in the comments section. Your insights will be valuable to all of us in the coding community.
