A '''text-based web browser''' is a [[web browser]] that renders only the [[text-based (computing)|text]] of [[web page]]s, and ignores most [[computer graphics|graphic]] content. Under small bandwidth connections, usually, they render pages faster than graphical web browsers due to lowered [[Bandwidth (computing)|bandwidth]] demands. Another use case is controlling web-based devices in a closed network via secure terminal connections using e.g. ssh, without any graphics capability, in addition to other [[text-based user interface]]s (TUI). Additionally, the greater [[CSS]], [[JavaScript]] and [[typography]] functionality of graphical browsers require more [[CPU]] resources. They also can be heavily modified to display certain content differently
 
Text-based browsers are often very useful for users with [[visual impairment]] or partial [[blindness]]. They are especially useful with [[speech synthesis]] or text-to-speech software, which reads content to users.
 
Another use case is controlling web-based devices in a closed network via secure terminal connections, without any graphics capability, in addition to other [[text-based user interface]]s (TUI). Here, the [[CPU]] resource is not the main concern, which means the web page can be rendered with a modern engine and then re-rendered for a text terminal to be sent over a low-bandwidth secure connection, e.g. using the [[ssh]] protocol.
 
[[Progressive enhancement]] allows a site to be compatible with text-based web browsers without compromising functionality to more sophisticated browsers, as the content is readable through pure HTML without CSS or JavaScript.<ref>{{cite web |title=Building a resilient frontend using progressive enhancement |url=https://www.gov.uk/service-manual/technology/using-progressive-enhancement |website=GOV.UK |date=16 December 2019 |access-date=27 October 2021 |language=en}}</ref>
