  The vision of providing access to all web content equally for all users makes
web accessibility a fundamental goal of today's internet. Web accessibility is
the practice of removing barriers from websites that could hinder functionality
for users with various disabilities. Web accessibility is measured against the
accessibility guidelines such as WCAG, GIGW, and so on. WCAG 2.2 is the latest
set of guidelines for web accessibility that helps in making websites
accessible. The web accessibility tools available in the World Wide Web
Consortium (W3C), only conform up to WCAG 2.1 guidelines, while no tools exist
for the latest set of guidelines. Despite the availability of several tools to
check the conformity of websites with WCAG 2.1 guidelines, there is a scarcity
of tools that are both open source and scalable. To support automated
accessibility evaluation of numerous websites against WCAG 2.2, 2.1, and 2.0 we
present a tool, WAccess. WAccess highlights violations of 13 guidelines from
WCAG 2.0, 9 guidelines from WCAG 2.1, and 7 guidelines from WCAG 2.2 of a
specific web page on the web console and suggests the fix for violations while
specifying violating code snippet simultaneously. We evaluated WAccess against
2227 government websites of India and observed a total of about 6.1 million
violations.
