Termy is a fast, native terminal for macOS, Linux, and Windows. It combines GPU-accelerated rendering with the terminal workflows you use every day—tabs, splits, search, tasks, layouts, themes, and optional tmux sessions—without turning the interface into a control panel.
- Damage-scoped GPU rendering with dirty-span cell caching
- Tabs, splits, search, tasks, and reusable layouts
- Configurable keybindings, colors, themes, and terminal behavior
- Optional tmux control-mode sessions
- Native platform integration with a reusable headless runtime and FFI
Install
Download the latest build from termy.sh/download or browse every artifact on GitHub Releases.
macOS DMGs from v0.2.75 onward are signed and notarized. Open the DMG and drag
Termy to /Applications. See macOS troubleshooting
if the app still does not open.
On Windows, run Termy-<version>-windows-x64-Setup.exe (or the arm64 one on
ARM64 PCs). It installs for the current user without an administrator prompt;
pass /ALLUSERS or pick Install for all users to install under Program
Files. See the installation guide
for SmartScreen and winget notes.
Build from source
Termy is a Rust workspace. Build and launch the desktop app with:
cargo run --release -p termy
See the installation guide for platform-specific steps.
What you can shape
Termy keeps its behavior in plain configuration rather than burying it in hidden application state.
| Surface | What you control |
|---|
| Appearance | Themes, colors, fonts, chrome contrast, and tab presentation |
| Input | Keybindings, terminal behavior, mouse reporting, and shortcuts |
| Workspace | Tabs, split panes, tasks, reusable layouts, and working directories |
| Sessions | Local shells and optional tmux-backed sessions |
Start with Customize Termy or use the complete configuration reference.
Architecture
Termy is more than a window around a PTY. Its terminal emulation uses Termy's own streaming parser, screen storage, and native PTY runtime. The repository also contains a GPUI desktop application, CLI, native FFI, website, and release tooling.
