Visual regression testing is the most popular type of testing for user interfaces. It helps to compare the wireframe with the actual implemented user interface. There are several tools in the market that help perform visual regression testing. Applitools, Testsigma, and Percy are the most popular tools for visual comparison. 

Earlier Applitools captured a major market share however in recent years organizations are shifting from Applitools to other tools. The curated list of Applitools alternatives helps in the migration of your visual regression framework.

What is visual regression testing?

Visual regression testing is a software testing technique that evaluates the visual appearance of a software application’s user interface (UI) or graphical user interface (GUI). It aims to verify the application’s visual elements such as text, colors, images, and fonts. 

Visual regression testing is often called by different names such as visual testing, and visual UI testing.

What is Applitools?

Applitools is a visual testing tool that aims to validate all elements of an interface, including text, images, layouts, videos, etc. Applitools is a commercial tool developed and managed by Applitools, Inc. Applitool uses AI-based visual validation, hence it provides stable and accurate results across platforms and devices.

Reasons to Consider Applitools Alternatives

Let’s discuss the reasons to consider the Applitools alternatives.

  • Cost: Applitools can be more expensive than similar testing tools. Organizations having small teams and limited budgets struggle to adapt. 
  • Learning curve: The learning curve for Applitools is comparatively high. The company needs to spend on high licensing costs and then they need to spend on training and learning, to use the tool effectively.
  • Limited support for manual testing: Applitools is designed for automated visual regression testing. Support for manual visual testing is limited. Teams that rely on manual testing and don’t have the required skill sets to automate are finding the tool-less helpful
  • Limited customization: Though Applitools comes with a wide range of features, based on the business requirement one might be interested in customization. Applitools supports limited customization.

What are the factors to consider while selecting an Applitools Alternative Tool?

Ease of use: Tools should be easy to use, and they should encourage self-learning.

Setup and installation: Setup and installation are a major phase of any automation framework. This may also demand skilled resources. Setup and installation should be easier.

Budget Constraints: The budget factor varies from organization to organization. However, commercial tools require you to pay license fees, and open-source tools are free. Commercial tools will provide dedicated support and additional benefits.

Visual comparison technique: Each tool uses a different mechanism to compare the images or screenshots. The tool should incorporate modern technologies, and it should provide the most stable and accurate results.

Integration: The tool should support integration with third-party tools. It may be CI/CD tools, versioning tools, software management tools, or bug-tracking tools. 

Code-based vs No-code: Skilled resources are often costly. If the tool supports no code testing then anyone can automate. Choice varies from organization to organization, however, it is easy to address the skill gaps with no code tool in place.

Reporting: The reporting should be in-depth and easily understandable. You should be able to customize the reports based on the need. If the tool provides all required reports in a single place such as functional, API testing, and visual testing reports, then it is easy to showcase them for stakeholders. 

Top 15 Alternatives for Applitools

There are many visual testing tools in the market. If you are migrating from Applitools it might take a week just to research and shortlist the alternatives. The below set of tools is curated for you, which may help in choosing the best fit for your organization.

Functional testing may not be enough to achieve high customer satisfaction. Functional testing doesn’t guarantee the correctness of the user interface. To ensure the user interface is behaving as expected the visual regression testing is crucial. Applitools, Testsigma, Percy, and Chromatic are a few popular tools in the market however as we listed, many test automation tools are less explored. Organizations are shifting from Applitools due to many disadvantages and for their own benefits. Testsigma is the closest alternative for Applitools. Based on your budget constraints, you may also be interested in open-source tools. Remember, open-source tools don’t guarantee long-term support and maintenance. Furthermore, the open-source tool requires many configurations and, in turn, requires skilled resources.
