Overview
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.
Who it is for
Contour suits advanced users who want terminal controls such as split panes, vi-like modes, and persistent sessions. Its platform support and GPU rendering may also suit users working across different operating systems or high-DPI displays.
What is good
- Free plan is listed at 0.00 USD per free.
- Supports Linux, macOS, FreeBSD, OpenBSD, and Windows.
- Sessions can persist and be reattached over a network.
- TCP connections are encrypted with TLS and require a token.
What to know first
- tmux -CC mode is not supported.
- Daemon mode is experimental.
- The project website is still in draft mode.
Verdict
Contour brings modal controls, persistent sessions, and broad text support to a free terminal emulator. Readers who depend on tmux -CC or stable daemon behavior should note those limitations.
