Contour 0.8 turns your terminal into something closer to a notebook: every command becomes a block with its own status, duration and collapsible output.

Contour is a cross-platform terminal emulator written in C++ on Qt 6, with GPU-accelerated rendering for smooth output and high-DPI displays. Version 0.8 adds interactive command blocks, output folding, clickable URLs and file paths, a graphical search bar, much higher throughput in the developers’ benchmarks, and broader shell integration. If you spend your day in logs, builds and SSH sessions, this release is aimed squarely at you.

⚡ Quick Summary

  • Command blocks: each command shows exit status, execution time, duration and working directory. Failed commands get red markers, running ones yellow.
  • Output folding: collapse long output to a single line, with a gutter for fold controls, optional line numbers and timestamps, and a sticky command header.
  • Speed: in the developers’ benchmarks, full-screen app throughput rose from 55.6 to 593.2 MiB/s, and colored text from 42.7 to 281.9 MiB/s.
  • Shell integration: expanded support for Bash, Zsh, Fish, Nushell and PowerShell, plus systemd OSC 3008 context tracking on systemd 258 or later.
  • Quality of life: desktop notifications for long commands, Ctrl+click on URLs and file paths, a graphical find bar and GPU selection.

What is Contour?

Contour is a modern, GPU-accelerated terminal emulator for power users. Its project description lists support for Linux, macOS, FreeBSD and Windows, font ligatures, full Unicode with emoji and grapheme clusters, Sixel images, vi-style input modes for selection and copy, runtime configuration reload, profiles and clickable hyperlinks through OSC 8. Earlier this year, version 0.7 added tabs, split panes and saved layouts. Release 0.8 now focuses on how you work with command output.

Command blocks and output folding

The biggest addition is interactive command blocks. Instead of one endless scroll of text, Contour tracks each command separately and annotates it.

📌 Per-command details

Exit status, execution time, duration and working directory are shown for each command.

🚦 Status colours

Failed commands receive red indicators, while commands that are still running are marked in yellow.

🗜️ Collapsible output

Fold a command’s output down to one line, which is handy for logs and commands that print hundreds of lines.

📏 Gutter and sticky header

A gutter provides fold controls, optional line numbers and timestamps, and a sticky command header keeps the relevant command visible while you scroll its output.

💡 Why it matters: when a build prints 800 lines and the failure is near the top, a sticky header and fold control save a lot of scrolling. Duration and exit status in the margin also make it easy to spot the one slow or failing step in a long session.

Navigation, notifications and search

FeatureHow it works
Jump between promptsCtrl+Shift+Up and Ctrl+Shift+Down
Copy commands or outputCopy a previous command or its output directly from the block
Long-command notificationsDesktop notification when a long-running command finishes in an unfocused pane. On by default for commands running 10 seconds or more.
Clickable URLs and pathsAutomatic detection, opened with Ctrl+click, including file paths with line and column numbers
Graphical searchA find bar with live match counts, navigation buttons and case-sensitivity controls, replacing the old text prompt

The line-and-column path support is a quiet win for developers: compiler errors that print file.cpp:42:7 can be opened straight from the terminal, depending on your setup.

Performance: the numbers

According to the developers’ own benchmarks, throughput improved substantially across the board. These are project figures for specific test workloads, so your results will vary with hardware, GPU and workload.

Better graphics support

Release 0.8 adds animation-frame support to the Kitty graphics protocol and speeds up parsing for image-heavy workloads, which is where the 7.55 s to 1.06 s improvement comes from. You can also now choose which GPU renders the terminal on Linux and Windows, useful on laptops with integrated and discrete graphics.

⚠️ Read benchmarks carefully. Terminal throughput numbers show how fast the emulator processes output, not how fast your commands run. You will notice it most when printing huge logs or running full-screen tools.

Shell integration

Command blocks depend on the terminal knowing where each command starts and ends. Contour 0.8 expands shell integration for Bash, Zsh, Fish, Nushell and PowerShell.

It also adds support for systemd’s OSC 3008 context tracking. On systems running systemd 258 or later, command boundaries, exit statuses and working directories can be provided without additional shell configuration.

For other setups, Contour can generate the integration script for your shell. Check the official documentation for the exact steps in 0.8, then follow the pattern below.

# Generate a shell integration script (choose your shell and a path)
contour generate integration shell bash to ~/.local/share/contour/shell-integration.bash

# Load it from your shell startup file
echo 'source ~/.local/share/contour/shell-integration.bash' >> ~/.bashrc

Other improvements and fixes

  • Better Unicode and font handling, plus configurable tab colours.
  • Remember window positions between launches (optional).
  • Fixes for terminal resizing, scrollback history, SSH connections, Flatpak notifications, persistent daemon sessions and Windows keyboard input.
  • Stability: several fixes for crashes, freezes and excessive memory usage.

How to install Contour

According to the project’s README, Contour is packaged for several distributions, and release packages are available on GitHub. Check that your distribution actually ships version 0.8, since packages often lag a release.

PlatformMethod
FedoraOfficial package: sudo dnf install contour-terminal
Arch LinuxOfficial package named contour: sudo pacman -S contour
openSUSE, VoidOfficial packages
Any distroFlatpak from Flathub: org.contourterminal.Contour
Ubuntu, othersRelease page offers an Ubuntu package, AppImage and static build
macOS, WindowsmacOS bundle and Windows installer on the release page
# Flatpak (works on most distributions)
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.contourterminal.Contour
flatpak run org.contourterminal.Contour

# Check your installed version (native packages)
contour version
💡 Admin tip: if you only want to try it, the Flatpak or AppImage keeps Contour separate from your system packages. Note that a sandboxed Flatpak terminal may have limited access to the host shell and tools, which can affect how useful it is as your daily terminal.

Who should try Contour 0.8?

✅ A good fit if you

  • Work with long logs, builds and test output
  • Want per-command status and timing without extra tools
  • Use a mix of Linux, macOS and Windows
  • Like GPU-accelerated, configurable terminals

⚠️ Think twice if you

  • Need the very latest version from a slow-moving distro repo
  • Rely on a multiplexer workflow you do not want to change
  • Prefer a minimal terminal with no extra UI
  • Cannot spend time on shell integration setup

Command blocks pair well with a multiplexer for remote sessions, so you do not have to choose one or the other. More Linux and developer-tool guides are on VMoreCloud.
