This tool makes it so much easier to check if images across a site have proper alt text, which is something we often overlook but is actually very important. The extension works smoothly and displays the alt attributes clearly, saving me a lot of time compared to inspecting elements manually. It’s especially useful during the QA phase or when doing SEO checks before launching a site. For developers like me, this is a simple yet powerful tool that helps ensure our websites are accessible and meet quality standards. Overall, it's a well-made extension that I highly recommend to fellow developers. If you're serious about clean, accessible, and SEO-friendly web development, this tool is definitely worth using.
- (2025-05-04) Carl Cayetano: As someone who works regularly with web accessibility and content auditing, the Alt Text Viewer extension has quickly become one of my favorite tools. It's lightweight, fast, and incredibly useful for anyone who needs to ensure that images on a webpage are properly described for screen readers. The extension works seamlessly in the background—once enabled, it highlights or overlays image alt text without disrupting the page design. I especially appreciate how it can reveal missing alt attributes too, which is crucial for identifying accessibility gaps. The user interface is clean and intuitive, with customizable settings that let you choose how and where the alt text appears. Whether you're a developer, content creator, or accessibility advocate, this tool is a must-have. It saves time, improves workflow, and reinforces good accessibility practices across the board. Highly recommended!
