Alacritty vs Contour

Alacritty is a free, cross-platform terminal emulator for Linux, macOS, Windows, and BSD. It uses OpenGL and is designed for high performance and extensive configuration, for people who spend substantial time in a terminal. Vi mode supports viewport and scrollback navigation, text selection, and copying with keyboard bindings; users can also search forward or backward through scrollback. Configurable regex hints can recognize visible text or links and pass them to an external application or trigger a built-in action. One instance can run multiple terminal windows, including through the alacritty msg create-window command. Alacritty is designed to integrate with other applications rather than recreate their functions, and URL-opening applications can be configured. Settings use a TOML file that the software does not create automatically. The project describes Alacritty as beta, with missing features and bugs still to address. It has no tabs, split panes, or graphical configuration editor, and requires OpenGL ES 2.0. Windows use requires ConPTY support on Windows 10 version 1809 or higher.

Contour is a free terminal emulator for everyday use, designed for people who want control over terminal workflows. It runs on Linux, macOS, FreeBSD, OpenBSD, and Windows. GPU-accelerated rendering and high-DPI support accompany text features such as font ligatures, Unicode grapheme clusters, and colored emoji. Users can split panes, use vi-like modes for navigation and selection, and jump through history with vertical markers. Sessions can persist beyond a terminal window and be reattached locally or over a network. Contour interoperates with tmux control mode in both directions, but not its -CC mode. It also supports clickable links, inline Sixel images, OSC 52 clipboard setting, and profiles for color schemes and login shells. TCP connections use TLS encryption and require a token. Daemon mode is experimental, and its command-line flags and wire protocol may change. The project website remains in draft mode. Contour is licensed under Apache License 2.0.
