Bring accessibility into your development workflow early
Shift accessibility left
Building accessibility testing into your development workflow early—known as “shifting left”—means catching issues before they reach production, when they’re faster, easier, and cheaper to fix. By testing, identifying, and fixing accessibility issues earlier, you can make a significant cost-saving impact at your organization, while delivering better user experiences across your products and services.

Frequently asked questions
What is digital accessibility, and why does it matter for developers?
Digital accessibility is the practice of ensuring digital properties (web and mobile) can be used by people with disabilities without barriers. It is about meeting global accessibility standards and legal requirements, but also building better, more inclusive user experiences.
For developers, making accessibility part of everyday workflows means catching issues early to reduce rework and ship higher-quality code faster. Accessible code is more maintainable, performs better across devices and assistive technologies, and leads to more positive outcomes for all users.
Can I run accessibility tests locally before committing code?
Yes. You can catch accessibility issues right in your local environment before opening a pull request. Running tests locally helps you identify and fix problems earlier in the development lifecycle. You can also configure rules to automatically block code from merging if it has accessibility issues, ensuring only compliant code gets merged.
How do I integrate accessibility testing into my IDE, CI/CD, or pipeline?
You can use Deque’s products to easily build accessibility testing into every stage of development. The Axe MCP Server connects the expertise of the Axe platform with your AI coding agent, giving you accessibility guidance directly in your IDE. You can also use Axe DevTools to integrate automated accessibility checks into your CI/CD pipeline and end-to-end tests, all while working within your existing systems, without losing velocity. This seamless integration makes accessibility a natural part of your workflow, helping you ship faster, prevent regressions, and deliver high-quality, inclusive code.
Are there free or open-source accessibility testing tools I can start with?
Yes, you can start with our free browser extension in Chrome, Firefox, or Edge, all run on Axe-core, Deque’s open-source accessibility testing engine. It allows development teams to run basic, automated accessibility tests on a page-by-page basis. It’s a great way to get introduced to automated accessibility testing and quickly catch common accessibility defects early in development.
Do you have tools to test for accessibility on web and mobile?
Yes, Deque provides accessibility testing tools for both web and mobile. You can leverage Axe DevTools for Web to test web experiences throughout development—within your IDE, browser, and CI/CD pipeline—catching issues early with automation and AI-powered checks. You can use Axe DevTools for Mobile to test any native or cross-platform app, even without source code access, in your pipeline or as you code, using automated UI tests and React Native linting. These tools integrate seamlessly into your workflows, helping you deliver high-quality, inclusive experiences across platforms.
