Unused CSS finder VS Sim Daltonism

Crawl your website and find unused CSS

From the perspective of a color blind person, some colors are impossible to distinguish.

Efficiency
Identifies unused CSS, resulting in cleaner and more efficient code. This can lead to improved page load times and reduced bandwidth usage.
Ease of Use
Provides a straightforward interface that allows users to quickly scan their websites and find unnecessary CSS without needing extensive technical knowledge.
Cost Savings
By eliminating unused CSS, it reduces the amount of data that needs to be transmitted and stored, potentially saving on hosting and bandwidth costs.
Improved Maintenance
With a reduction in CSS file size, future maintenance becomes easier and more manageable, making it simpler to update or refactor code.

False Positives
May incorrectly identify CSS as unused if the tool does not recognize dynamic changes or conditional loading, which can lead to accidental removal of necessary styles.
Dependency on External Tool
Relying on an external tool could present privacy and security concerns, especially when sharing potentially sensitive code and styling information.
Manual Verification
Requires manual verification of results to ensure important styles are not removed, which can be time-consuming and somewhat negate the tool's time savings.
Incompatibility with Complex Frameworks
Might not effectively handle complex CSS frameworks or preprocessors, where styles are used indirectly or dynamically through Javascript or server-side frameworks.

Accessibility Awareness
Sim Daltonism helps users understand how colorblind individuals see by simulating different types of color blindness, increasing awareness and fostering inclusivity.
Real-time Simulation
The application provides real-time simulation, making it easier for designers to see how their work looks to colorblind users instantly.
Free to Use
Sim Daltonism is available for free, making it accessible to a wide range of users who need to consider colorblind accessibility in their work.
Multiple Types of Color Blindness
The tool supports various types of color blindness, including protanopia, deuteranopia, and tritanopia, allowing users to test their designs against multiple scenarios.
Easy to Use
The software is user-friendly and simple to set up, requiring minimal technical knowledge to start using effectively.

MacOS Only
Sim Daltonism is only available on MacOS, limiting its accessibility to users on other operating systems such as Windows and Linux.
Limited to Screen Content
The app only simulates colors on the screen, which can be a limitation for testing printed materials or non-digital designs.
Dependency on Screen Calibration
The accuracy of the simulation can be affected by screen calibration, potentially leading to inconsistent results across different devices.
Lack of Integration
Sim Daltonism does not integrate directly with design software, requiring users to run simulations as a separate process which can interrupt workflow.
No Prototyping Features
Unlike some other accessibility tools, it doesn't offer additional prototyping or testing features beyond color vision simulation.
