A11yDock is a free Chrome add-on designed for accessibility auditing, enhancing manual evaluations with script-driven overlays. It addresses limitations of automated testing by revealing semantic structures and ambiguous patterns that require human interpretation. Each module can be toggled for a detailed review process, focusing on critical accessibility signals like label associations and heading structures. The tool’s visual design is neutral and ergonomic, providing cues to assist accessibility judgments without automating the process.

The architecture of A11yDock allows for independent or combined execution of audit scripts, ensuring the integrity of the Document Object Model (DOM) is maintained while improving the efficiency of accessibility reviews. By integrating contextual overlays into standard development and auditing workflows, A11yDock streamlines the evaluation process, making it a valuable resource for developers and accessibility reviewers.
