AChecker is an open source Web accessibility evaluation tool. It can be used to review the accessibility of Web pages based on a variety international accessibility guidelines.

Automated accessibility checkers can only identify a limited number of barriers in Web content with certainty. A human must interact with an accessibility review to make decisions on potential problems automated tools can not identify. For example, any check that requires the evaluation of meaning, such as whether link text accurately describes the purpose of a link, or whether Alt text sufficiently describes the meaning contained in an image, a human must make a decision.
