Public Beta — October 1st

Mado.

The terminal multiplexer for macOS.

Split your workspace, run plugins in the sidebar, pick a theme, and never leave your terminal again. Mado is native, fast, and built entirely around the keyboard.

Everything in one window

No tabs. No window switching. Just your work, organised exactly the way you want it.

🪟

Split Panes

Divide your workspace with Cmd+D (vertical) or Cmd+Shift+D (horizontal). Jump between panes with Cmd+Opt+Arrows. Close with Cmd+W. Every split layout is saved per project and restored exactly as you left it.

⌨️

Keyboard-Driven

Every action in Mado has a keyboard shortcut. Toggle sidebars, switch between panes, open plugins, show the help overlay — all without lifting a hand from the keys. Built for developers who already use tmux, Neovim, or Helix and don't want to slow down for a mouse.

🎨

Twenty-Two Themes

Switch between twenty-two hand-crafted themes built on Tailwind CSS palettes — Slate, Indigo, Emerald, Rose, Amber, and more. Each theme coordinates the terminal colours, focus indicators, sidebar chrome, and toolbar into a cohesive look. One line in your config to change everything.

🔌

Sidebar Plugins

Extend Mado's sidebar with plugins written in any language. Each plugin renders its own pixel frame — no web views, no Electron overhead. Mado ships with a clock, Pomodoro timer, clipboard history manager, system stats monitor, and an AI assistant, ready to use out of the box.

Built-in Integration

Tasku, right in your sidebar.

Mado ships with first-class support for Tasku — NerimaSoft's terminal task manager. Your tasks, projects, priorities, and workspaces live in the left sidebar, always a glance away without interrupting your flow.

Switch between projects in the Tasku panel and Mado switches with you — restoring the exact pane layout you had open for that project. Your terminal workspace and your task list stay in sync, automatically.

Tasku is free, open source, and installs in seconds. If you're already using it, Mado picks it up immediately. If you're not, there's no better place to start.

One command. One file.

Most terminal tools make you hunt through nested directories, manually edit JSON, or memorise config paths you'll never remember next week. Mado takes a different approach.

Run mado config and your configuration opens instantly in $EDITOR — the same editor you already use for everything else. It's a single TOML file: set your theme, choose your font, define your shell, and declare which plugins you want in which sidebar. That's it. No subdirectories, no schema to look up, no restart dance.

The same goes for themes. Drop a .toml file into ~/.config/mado/themes/ and it appears in the theme list automatically. Plugins work the same way — point the config at an executable and Mado handles the rest. Simple conventions over complex infrastructure.

# ~/.config/mado/config.toml # Open this with: mado config theme = "slate" font_size = 16.0 font_family = "Hack Nerd Font Mono" shell = "/bin/zsh" # Left sidebar plugins [[plugins]] id = "clock" command = "~/.config/mado/plugins/clock" kind = "pixel" icon = "🕐" [[plugins]] id = "ai" command = "~/.config/mado/plugins/ai" kind = "pixel" icon = "✦" position = "right"

Run mado config to open this in your editor. Changes take effect on next launch.

Your terminal, your colours.

Mado ships with twenty-two themes — one for every mood, project, or client. Each theme is more than a colour swap: the terminal foreground and background, the sidebar chrome, focus borders, toolbar tints, and active indicators are all coordinated so the interface feels deliberate rather than patched together.

Themes are built on Tailwind's colour palettes, so they're perceptually balanced and readable at any font size. Prefer something completely custom? Create a .toml file in ~/.config/mado/themes/, define your colours, and Mado picks it up automatically — no restart, no rebuild, just a file.

Switch themes with a single line in your config. Everything — the terminal colours, the sidebar, the focus ring — updates at once.

A sidebar that earns its space.

Mado's sidebar doesn't just show a file tree and call it done. It runs fully independent plugins — each a small program that draws its own UI and reacts to keyboard and mouse input.

Mado clock plugin

Clock

A clean, full-width clock that sits above the sidebar. At a glance, always visible, never in the way.

Mado Pomodoro plugin

Pomodoro Timer

Start a 25-minute focus session with a keypress. The timer counts down in the sidebar so you stay aware without switching apps.

Mado clipboard history plugin

Clipboard History

Every item you copy is captured and searchable. Click an entry to paste it directly into the active pane — no external clipboard manager needed.

Mado Tasku stats plugin

Stats (Tasku)

At-a-glance Tasku project stats in the right sidebar — tasks by status, priorities, and project health. Your work data, right where you're already looking.

Mado priorities panel

Priorities (Tasku)

Drag your projects into priority order in the sidebar. Keep your highest-priority work front and centre — a quick visual reminder of what actually matters today.

Mado workspaces panel

Workspaces (Tasku)

Your Tasku projects displayed as colour-coded tiles in the sidebar. One click switches your active project — Mado restores the exact pane layout you had open last time, instantly.

Mado AI assistant plugin

AI Assistant

An AI assistant panel, right next to your terminal. Ask questions, explain error output, or draft a command — without leaving Mado or opening a browser.

Build your own

Any executable that speaks the Mado plugin protocol becomes a sidebar panel. Write in Rust, Python, Go, Ruby — whatever you're comfortable with. Plugins render raw pixel frames, so your UI is limited only by your imagination.

Built for the terminal. Not the browser.

Most modern terminal emulators are built on Electron. That means a full Chromium engine, hundreds of megabytes of RAM, and a startup time that reminds you of a browser opening a web page — because that's essentially what's happening. Mado is different. It's a native macOS application written in Rust with a Slint UI layer — no browser engine in sight. It starts in milliseconds, uses a fraction of the memory, and renders at 60fps.

The multiplexer model is familiar if you've used tmux or GNU Screen, but Mado doesn't require you to learn a modal command language or remember prefix key sequences. Split panes, focus navigation, and session management are all first-class keyboard shortcuts — discoverable with Cmd+/ at any time. If you can learn Cmd+D to split and Cmd+W to close, you already know enough to be productive.

Workspace persistence is built in. When you switch projects in the sidebar, Mado parks the current layout — all panes, their working directories, and their scroll positions — and restores it when you come back. No manual session saving, no tmux-resurrect, no lost context. Your work is exactly where you left it, every time.

The plugin system exists because a terminal multiplexer lives on screen all day. If you're going to give it that prime real estate, it should earn it. Rather than baking in a file tree or a fuzzy finder and calling it done, Mado lets you put whatever you actually use in that sidebar space — and lets you write it in whatever language you know best.

Mado is a tool for people who are already productive in the terminal and want a multiplexer that gets out of the way. No accounts. No cloud sync. No telemetry. Mado is open source and free — the code is on GitHub, and it always will be. Just a fast, configurable terminal multiplexer that runs on your machine.

Frequently Asked Questions

Mado launches as a public beta on October 1st, 2026. Sign up below to be notified the moment it's available.

Mado is open source and free. The full source is on GitHub — you can read it, build it yourself, or contribute. There are no paid tiers planned at launch.

Yes. Mado is fully open source — the repository is on GitHub and licensed so you can read the code, build from source, or contribute. No closed-source components, no proprietary licensing tiers.

Mado runs on macOS, targeting Ventura (13) and later. Native ARM64 builds are available for Apple Silicon, with Intel Macs supported via Rosetta 2.

Not at launch. Mado is macOS-only for October 1st. Linux and Windows are on the roadmap — the underlying Rust and Slint stack supports them — but we want to ship a polished macOS experience first.

iTerm2 is a feature-rich terminal emulator but doesn't have a built-in multiplexer or sidebar plugin system. Warp is built on Electron and focuses on AI-first command completion — Mado is native and lets you bring your own shell and workflow. Kitty is fast and cross-platform but requires manual configuration for tiling. Mado combines native performance with a keyboard-driven multiplexer model and an extensible sidebar, targeting developers who want everything in one window without learning a new shell.

Yes. Any executable that speaks the Mado plugin protocol can become a sidebar panel. Plugins receive resize and input events via stdin as JSON and render by writing raw pixel frames to stdout. You can write them in Rust, Python, Go, Ruby, or any other language. Plugin documentation will be published at launch.

When you switch projects in the Mado sidebar, the current pane layout is parked — all splits, working directories, and scroll positions are saved. Switching to another project restores that project's layout exactly. You can have as many projects as you like; Mado tracks them all without any manual save step.

Mado ships with twenty-two themes based on Tailwind CSS palettes: Slate, Gray, Zinc, Neutral, Stone, Red, Orange, Amber, Yellow, Lime, Green, Emerald, Teal, Cyan, Sky, Blue, Indigo, Violet, Purple, Fuchsia, Pink, and Rose. You can also create custom themes by adding a .toml file to ~/.config/mado/themes/.

No. Mado has no telemetry, no analytics, and no network calls built in. It runs entirely on your machine. The only network activity is from your own shell sessions and any plugins you choose to install that make network requests.
