The best Linux terminal setup is assembled from separate parts: a terminal emulator, a shell, and—if you want them—a custom prompt and a multiplexer. You do not need to write a terminal emulator from scratch. Choose each layer for the way you work, configure it separately, and add complexity only when it solves a real problem.
What “building a terminal” means
People often use “terminal” to mean several different things. Keeping the layers straight makes setup decisions easier:
- Terminal emulator: The desktop application that displays text and accepts keyboard input. It starts a shell or another program. Alacritty and WezTerm are two configurable options.
- Shell: The command interpreter, such as the one your Linux account already starts. It handles commands and has its own startup files.
- Prompt: The text or symbols that indicate the shell is ready for input. Starship can provide a configurable prompt across shells.
- Multiplexer: Optional software that manages terminal sessions, windows, or panes. tmux can keep sessions available to reattach after disconnecting.
These parts are related, but they are not interchangeable: changing the emulator does not automatically change your shell or prompt.
Choose the emulator for its features and configuration style
There is no evidence here for a universal “best” emulator or a directly comparable speed ranking. Decide based on the features you need and how you prefer to configure software.

| Option | What its documentation supports | Consider it if |
|---|---|---|
| Alacritty | Cross-platform emulator with documented Linux and BSD support, vi mode, scrollback search, regex hints, and multi-window features. Its configuration can specify a shell program and arguments. Project features; version 0.14.0 configuration reference. | You want a configurable emulator with these documented features and prefer its configuration approach. |
| WezTerm | Available for Linux and other platforms, with source builds documented. It supports Lua configuration, shell integration through OSC sequences, and configurable program launching. Installation; Shell integration; Launching programs. | You are comfortable with Lua, want its documented shell integration, or prefer an option that can be built from source. |
Features and project claims do not establish which emulator will be fastest on your particular hardware. Choose based on a feature you will actually use rather than treating a performance label as a benchmark.
Decide which shell should start
Your emulator launches a program; that program is often your shell. Some emulators let you set the shell explicitly. Alacritty’s configuration reference, for example, documents a shell program and arguments. WezTerm’s POSIX launch behavior uses the shell configured for the user in the password database and launches it as a login shell by default. Consult the emulator’s current documentation before changing launch settings.

Keep shell selection separate from prompt customization. First confirm that the shell you want starts correctly and that its normal startup files work. Shell startup files are where you initialize shell-specific tools such as a prompt.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsAdd Starship if you want a configurable prompt
Starship is a cross-shell prompt tool. Its documentation explains shell-specific initialization and configurable modules; follow the instructions for the shell you use rather than copying initialization for a different shell. See the Starship project and its configuration documentation.

If you want Starship’s intended glyph setup, install and enable a Nerd Font in the terminal emulator. Without the required font, glyphs may not display as intended. Configure the prompt after the shell itself is working, so a prompt issue is easier to distinguish from a shell-launch issue.
Add tmux only when sessions or panes help
tmux is optional. The project describes it this way: “tmux is a program which runs in a terminal and allows multiple other terminal programs to be run inside it.” Its sessions, windows, and panes can help organize work, and sessions can be detached and reattached. That can be useful when you want a session to remain available after disconnecting from it.

When tmux is involved, the TERM value matters because programs use it to identify terminal capabilities. The tmux FAQ advises using an appropriate tmux or screen terminal description inside tmux, such as tmux-256color. See the tmux FAQ. If colors or other terminal features behave incorrectly, check this compatibility setting rather than assuming the emulator is at fault.

Build the setup one layer at a time
- Identify what you want to improve. Is the issue appearance, keyboard navigation, windows, shell choice, prompt information, or keeping work available after a disconnect? Start with the actual friction instead of installing every component.
- Choose an emulator. Compare the documented features and configuration style of options such as Alacritty and WezTerm. Keep your existing desktop terminal available until the new setup works.
- Set and verify the shell. If you need a different shell, configure the emulator’s launch behavior as documented. Open a fresh terminal and confirm the expected shell starts before changing prompt settings.
- Configure the prompt, if wanted. Follow Starship’s initialization instructions for your shell. Install and enable a Nerd Font in the emulator if you want the glyph setup.
- Add tmux if its workflow is useful. Configure sessions, windows, or panes only as needed, and check the terminal description when applications behave differently inside tmux.
- Make changes recoverable. Keep a copy of configuration before editing it, change one layer at a time, and test changes in a fresh shell or session. If a new setting prevents a clean start, restore the copy or temporarily return to the desktop terminal to fix that layer.
What “best” should mean for your setup
A good setup is the combination that fits your workflow and is understandable enough to maintain. The available documentation describes features and configuration, not a universal winner. Choose an emulator for its interface and controls, a shell for command-line work, a prompt for information you want at a glance, and tmux only if its session and pane model is useful to you.
