Blazingly fast. Memory-unsafe and faster than yours. Shitty is built for low latency, fast startup, and predictable resource use. It keeps terminal state on the CPU and renders cells with native compute backends: Vulkan on Linux and Metal on macOS. Performance 100MB catted through the GUI on an Apple-silicon MacBook, every terminal equalized first: Menlo 12pt, the same 14x28px cell, an 80x24 grid, 500 lines of scrollback. Best wall time of three runs.
