Treejack Product Overview

Treejack software stands out in the UX design toolkit as a focused tree-testing tool, empowering users to refine website navigation through insightful card sorting and first-click tests that feed directly into the design process. Aimed primarily at UX professionals and information architects, Treejack helps validate the tree structure of a website or intranet, ensuring that categories and subcategories are intuitive for users to navigate.

It offers a suite of research methods, including benchmarks and pilot tests, to measure user experience by tracking the success rate, correct answer paths, and instances of backtracking. Key features include the ability to conduct tests with real users (testers) who interact with your navigation menus as they would in the wild, while you gain valuable data on findability and iterate the structure before and during the development process.

Additionally, Treejack works easily with Chalkmark to capture first-impression data through screenshots, helping to align the tree structure with the visual design for maximum clarity and efficiency. This combination of features positions Treejack not just as a tree testing tool but as a comprehensive study for informing and validating UX design and website navigation.


  • Intuitive Analysis: Treejack simplifies the interpretation of test results. This means users can quickly understand where navigation fails and succeeds.
  • Task Testing: The software excels in setting up task-driven tests. This allows for focused insights into specific user tasks and navigation efficiency.
  • Participant Recruitment: Treejack offers integrated participant recruitment. This streamlines the process of finding and managing test subjects.


  • Learning Curve: Some users find the initial setup complex. This indicates a steeper learning curve compared to some other tools.
  • Limited Customization: The options for customizing tests are not as extensive. This can hinder users looking to create highly tailored test environments.
  • No Real-time Collaboration: Treejack lacks real-time collaborative features. This means teams cannot work on tests simultaneously within the platform.

Expert Opinion

In my experience, Treejack is a robust tool with a focus on testing and improving information architecture. While it might not offer as many customization options as some competitors, its targeted task-based approach provides a precise and valuable perspective on how real users navigate a site. Its visualizations are clear and aid in quick decision-making, though the initial setup can be a bit daunting for newcomers.

When judging its place in the market, Treejack outperforms in its analytical depth but can underperform for teams seeking collaborative features. It is best suited for environments where individual work on information architecture is paramount, and detailed task analysis is required to improve user navigation.

Treejack: The Bottom Line

Treejack brings a unique angle to website structure testing by focusing intently on task completion and user pathways, something not all product design tools prioritize. It offers a no-frills, in-depth analysis that is particularly good for identifying exactly where users get lost or confused. Its reporting features, which convert complex data into understandable visualizations, are noteworthy for those who need to make informed decisions about their website's information architecture.

Treejack does not promote a wide array of out-of-the-box integrations. However, it provides API access, which enables users to connect their Treejack data with other tools and systems they use. This API can be particularly useful for those looking to automate parts of the user testing process or integrate user testing data with other customer experience tools. Currently, there are no specific add-ons to extend the platform's capabilities, but the API access provides a versatile means for custom extensions.

However, once the tests are configured, the process for participants is generally straightforward.

Customer Support

Treejack offers customer support, but the depth of its resources isn't as comprehensive as larger competitors. Users have access to documentation and can contact support for help, but there may be a wait for a response. Some users express frustration with limited immediate support options, such as live chat or instant responses, which are often available with larger platforms.

Treejack Use Case

Who Would Be A Good Fit For Treejack?

In my experience, Treejack serves well for UX researchers, information architects, and designers who focus primarily on the structure and navigability of their websites or applications. Its most loyal customers tend to be professionals dedicated to refining information hierarchy, who value direct feedback on user navigation paths.

Small to medium-sized teams within larger enterprises or design-focused agencies make the most out of Treejack, especially those dealing with complex site structures in industries like e-commerce, educational technology, and large content-driven sites.

Who Would Be A Bad Fit For Treejack?

Treejack might not suit those who require a full suite of design and prototyping tools integrated into one platform. Disappointed customers are often from environments where the workflow demands more collaborative features, vector-based design capabilities, or robust prototyping tools.

Large design teams in need of comprehensive design-development platforms, startups on tight budgets who need all-in-one tools, or industries like gaming where interaction design is paramount, may find Treejack lacking.
