Zutty is a terminal emulator for the X Window System, functionally similar to several other X terminal emulators such as xterm, rxvt and others. It is also similar to other, much more modern, GPU-accelerated terminal emulators.

Zutty uses a radically simple, yet extremely efficient rendering implementation, coupled with a sufficiently complete feature set to make it useful for a wide range of users. It also offers high throughput with low latency, and strives to conform to relevant standards, either published or de-facto.
