Truwex Online: An accessibility and quality validator
Another nice feature is that Truwex creates a “Page Map” that highlights any issues it has found. Great for finding text with insufficient contrast, for instance (yes, I’m aware that there are a few borderline cases of that here).
As with all software tools that try to “validate” accessibility, the results Truwex provides have to be carefully analysed by a human. There’s no getting away from that. But still, it’s good to have another tool to help produce high quality sites.
