Alacritty is a blazing fast, GPU accelerated terminal emulator. It’s written in Rust and uses OpenGL for rendering to be the fastest terminal emulator available....
alacritty is the result of frustration with existing terminal emulators. using vim inside tmux in many terminals was a particularly bad experience. none of them were ever quite fast enough. even so, linux does have some decent alternatives. for example, urxvt and st give good experiences. the major downside with those options is difficulty of configuration and inability to run on nonx11 platforms. the options for macos are particularly slow–especially with a fullscreen terminal on a 4k monitor. none of these terminals are crossplatform–they are usually married to the windowing and font rendering apis of their native platform.
