Free WCAG 2.1 accessibility scanner for websites

A straightforward assertion library for Python.

Not present

User-Friendly Interface
The Web Accessibility Checker provides a straightforward and intuitive interface that makes it easy for users, even those with limited technical skills, to navigate and use the tool effectively.
Comprehensive Testing
The tool offers extensive accessibility testing against various standards, such as WCAG, to ensure that websites are accessible to all users, including those with disabilities.
Detailed Reports
It generates detailed reports that highlight specific accessibility issues, providing developers with clear insights into what needs to be corrected to enhance web accessibility.
Real-Time Feedback
The checker offers immediate feedback on accessibility issues, enabling developers to take corrective actions quickly during the development process.

Limited Free Features
Some of the more advanced features of the Web Accessibility Checker may require a paid subscription, limiting the capabilities available to free users.
Potential Over-Reliance
There's a risk that developers might rely too heavily on automated tools like this one and overlook the importance of manual accessibility testing and user feedback.
False Positives
As with many automated testing tools, there can be instances of false positives, where issues are flagged incorrectly, leading to potential confusion or unnecessary work.
Learning Curve for Detailed Usage
While the basic features are user-friendly, fully leveraging the tool's capabilities may require some learning and understanding of accessibility guidelines and how they apply to specific web content.

Fluent API
Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
Chainable Assertions
It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
Comprehensive Assertion Methods
The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
Extensibility
Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
Pythonic
Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Learning Curve
Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
Limited by Python Version
The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
Performance Overhead
The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
Less Community Support
Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
Dependency Management
Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

Web Accessibility Checker is a solid tool for identifying common accessibility issues on websites, helping developers and content creators improve compliance with standards like WCAG. While no automated tool can catch every issue, it serves as a useful starting point for accessibility audits.

Quickly scans web pages for common accessibility violations against WCAG guidelines
Helps identify issues like missing alt text, poor color contrast, and improper heading structures
Provides actionable feedback that developers can use to remediate problems
Useful for maintaining legal compliance with accessibility regulations such as ADA and Section 508
Saves time compared to fully manual accessibility reviews for initial assessments

Web developers wanting to catch accessibility issues early in the development process
Content creators and site owners aiming to improve inclusivity for users with disabilities
Organizations needing to meet legal accessibility compliance requirements
