Pros
Pro Can be used with any shell
ConEmu allows running CMD, PowerShell, Cygwin, PuTTY, TCC/LE, etc.
Pro Highly customizable
You can configure a plethora of settings, including shortcuts and aesthetics (background image, transparency, colors, and fonts) per software.
Pro Explorer integration
ConEmu integrates well with Explorer.
Pro Highly configurable hotkeys
Hotkeys allow the user to easily trigger an action and can be configured to their liking.
Pro Tab support
ConEmu allows the user to create tabs (Win+W by default) for separate instances of the terminal window, allowing them to have both multiple shells and multiple instances of the same shell open. The user can also set up a startup directory for each tab and run each tab as a specific user or rights.
Pro Run DOS applications with DosBox
If you have both ConEmu and DosBox installed, you can run DOS applications (and games) within a 64-bit OS environment.
Pro Integrates with FarManager
ConEmu was originally designed as an updated front-end specifically for the FarManager, which means it has increased functionality.
Pro Progress Bar integration
ConEmu permits the user to check up on the progress of an operation with a quick glance at the taskbar, without needing to bring the app to the foreground.
Pro Useful status bar details
Not only does the status bar show detailed information out-of-the-box, it can be configured for your specific needs.
Pro Free and open source
ConEmu is licensed under New BSD which is a class of very simple and liberal software licenses.
Pro Dynamically resize the window
You can change the width and height of the console window without having to reset your session.
Pro Run simple GUI apps within a ConEmu tab
With -new_console and -cur_console switches you can run simple GUI apps in a ConEmu tab (or split).
Pro Transparent, Quake-style mode
You can set up ConEmu as a transparent, Quake-style console by following these instructions.
Pro Supports borderless mode
To put ConEmu in borderless mode:
Set Main -> Appearance -> Frame Width to 0
Pro Supports Jump Lists
ConEmu allows pinning commands to Jump Lists (available in Windows 7 & 8; accessed by right-clicking the application in the taskbar), giving you quick access to common tasks and configurations.
Pro Search in console input/output history
ConEmu supports searching in all text that has been printed or entered in the console history.
Pro Actively developed
ConEmu is under active development. Updates roll out almost daily with bugfixes and new features.
Pro Box selection
ConEmu offers multiple, configurable ways of interacting with text, including an ability to select text in a rectangular way.
Pro Built-in screenshot tool
The screenshot tool allows the user to capture their computer desktop or anything shown on their computer screen in a static image file.
Pro Auto discovers your shells
Zero config gets you all your installed shells.
Pro Closest replacement for iTerm2 users
Supports many of the features that iTerm users have become accustom to (like multiple tabs, highlighting, configurable scroll bars, decent support for themed color pallets to support basic/solarized/etc.).
Pro Works well with Vim/Neovim on Windows
There were issues before that forced me to use graphical versions of Vim/Neovim, but latest versions of Conemu + Neovim, seem to be working much better on Windows now.
Pro Works well with WSL/Tmux/Neovim/SSH
There were issues before in the WSL usage scenario that forced me to use an X gui terminal using X forwarding, but now Conemu is working great, and is the only terminal I use from Windows/WSL.
Pro Easily split panes
There is a keyboard shortcut that makes it easy to split a window and create more panes.
Pro Windows linked to sessions
tmux calls the individual shell instances windows. They are displayed like tabs in the status line. These windows can be shared between different sessions, so that any given shell instance can be in any number of tmux sessions used for different purposes or by different users. This allows configurations like the following example: User A: wAB, wA1, wA2; User B: wB1, wAB, wB2
Pro Preserve the state
As long as you don't close your session, you may even lose your SSH connection, it'll keep your state just as it was. So you can resume where you left off (via tmux attach
).
Pro Maximize screen space
As a tiling window manager, it'll make use of all the space. As you have multiple workspaces and you can resize, etc. you can adjust to see what matters most.
Pro Frequently updated
Tmux is in a state of constant development. Updates are frequent and bug reports usually get an answer within days.
Pro Customizable
Open ~/.tmux.conf to get started. You can customize keybindings, the bottom status bar, color schemes, the clock screen, your time zone, and more.
Pro Mouse support
Mouse support can optionally be enabled, allowing e.g. scrolling with the mouse wheel, or switching panes with mouse clicks.
Pro Only need to learn a few keyboard shortcuts and commands to make much headway
Cons
Con Default look is somewhat unpleasant
In order to get a more pleasant look and feel, you may need to customize ConEmu yourself.
Con Layering of features per tab works with limited functionality
Can't do all of this, but it can theme colors per terminal:
Tab 1: I want it transparent, with a fixed background, with a certain color scheme, running powershell
Tab 2: Similar thing, but different bg, theme, and running posh as admin
Tab 3: Similar thing, but different bg, theme, and running cygwin
Con Bad scrolling support
The mouse wheel scroll doesn't transfer to terminal applications by default. It moves to the blank space instead of scrolling actual text content. This is especially true for ConEmu where there doesn't seem to be a way to make it work better.
Con It is slow
If you have a console process that outputs a lot, ConEmu will be the slowest option. Everything else will be faster. Even Terminus, which is, common, a packed web browser app. In my tests if ConEmu takes one unit of time, Terminus and Windows Terminal will be 0.6, FluentTerminal 0.35, Alacritty 0.3.
Con Poor performance with WSL
Con Screen scrapes from real console
ConEmu always runs the standard Windows console - ‘real console’, but it is hidden most of time.
This adds overhead, introduces another layer of complexity, and frequently creates irritating strange glitches (lost keys, messed up spacing) for heavy users.
Con Only simple, black and white emoji
It's not much, but is sad we can't get colored emojis. May change soon, I'm working on a PR.
Con No remote connections
A terminal emulator should emulate a terminal, i.e. a local input/output device to a remote computer. ConEmu can only run local processes in a window (albeit nicer than the local command shell window).
Con Poorly designed key binding
Counter-intuitive keyboard shortcuts make tmux very hard to use and learn.
Con Bad scrolling support
Con No builtin telnet or serial support
It's considered bloat by the maintainers and for this reason there's no builtin support for them.
