Coblis VS Unused CSS finder

If you are not suffering from a color vision deficiency it is very hard to imagine how it looks...

Crawl your website and find unused CSS

User-Friendly Interface
Coblis features a simple and intuitive interface, making it easy for users to upload images and see how they appear to individuals with different types of color blindness.
Multiple Simulations
The simulator provides several types of color blindness simulations, such as protanopia, deuteranopia, and tritanopia, allowing users to comprehensively understand how people with various color vision deficiencies perceive colors.
No Installation Required
Coblis is an online tool that doesn't require any software downloads or installations, which makes it accessible from any device with an internet connection.
Free to Use
The tool is free, providing access to color blindness simulations without any financial barriers.

Limited Advanced Features
Coblis may lack advanced features and customization options that some professional users or developers might need for in-depth analysis or integration purposes.
Internet Dependence
Since Coblis is an online tool, its use is dependent on having a stable internet connection, which might be a limitation in areas with poor connectivity.
Image Quality
There can be limitations in the quality and accuracy of image rendering, which might not fully replicate how images look to those with color blindness in all situations.

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.
