Shift-left accessibility testing
Save time and money on accessibility testing. Shift left and catch accessibility issues early in the development process. Maintain compliance and ensure digital equality.
What is shift-left accessibility testing?
Shift-left accessibility testing is an approach where testing is performed earlier in the design and development process, rather than waiting until the end of the development cycle or after the product has been released.
By catching accessibility issues sooner, you save time and money, free up your team for new feature development, and build more accessible products and services, reducing compliance risk and expanding your market share.

Benefits of shifting left
End the break-fix testing cycle and eliminate backlogs.
Make accessibility fast, easy, and second nature for dev teams.
Lower the cost of digital accessibility testing.
Why shifting left is more important than ever
As of 2024, 96% of the top one million home pages have accessibility failures. Why?
The reality is, innovative companies like yours are leveraging AI and automation to accelerate content creation, but accessibility testing isn’t keeping up. Fortunately, by enabling your teams with automated, AI-powered accessibility testing tools, your company can get ahead.

“I think what is amazing about the world we live in now, is we don’t really have to care so much about how to do these things because they come in tools that we use in our daily work.
So we’re just monitoring deployment feature flying, data vision — test data management, accessibility testing, we can get these capabilities in the tools that we use. And we don’t have to pester someone for weeks to have someone look at our code, just get the fast feedback.
These are conditions that allow us to have focus, flow and even joy in our work.”

Frequently asked questions
Organizations rely on Deque to help them shift left through a variety of approaches. The most important approach is to ensure development teams are on board. Axe DevTools, strategic consulting or coaching and training are great places to start.
Some organizations believe that accessibility testing takes too much time and expertise to shift left onto Development teams. These organizations should start an axe DevTools free trial to see just how easy it actually is to make a huge difference – while minimizing the impact on development velocity.
Fixing accessibility issues is exponentially less expensive the closer the tester is to the original code. From our studies, shifting into development can be 75% less expensive and 3x faster than using axe-core and manual testing later in QA or production.
