Chawan: TUI web browser
# Chawan: TUI web browser
Chawan is a text-mode web browser and pager for Unix-like systems, with<br>a focus on implementing modern web standards while remaining<br>self-contained, easy to understand and extensible.
It includes functionality such as CSS, inline images inside the terminal,<br>and JavaScript through a small, independent browser engine.
Most of Chawan has been developed from scratch in the memory-safe<br>Nim programming language.<br>## Download
