Lynx
Lynx is one of the most popular text-based browsers. After starting it, you may browse normal websites, typing "g" and then the address. Lynx shows you then how the website is normally seen by search engine spiders. This allows you to test if your content in you fallback version is accessible when nothing else works. You can also use it to think about better titles, headings and keywords to describe the purpose of the content. Take a look at the Lynx 8 for more information.
