Tiri

A Mac workspace for coding agents. Change it by asking, down to its source.

Why not something else?

If you pick	like	you give up
An AI editor	Cursor, Windsurf, Zed	Your agent. Theirs comes first, and yours gets a drawer under the editor.
The vendor's app	Claude Code desktop, Codex app	Every other agent, and the CLI you set up.
An agent manager	Conductor, Superset, Emdash	Your repo as you use it. Every job becomes a task in a fresh worktree.
A terminal	cmux, Warp, Ghostty + tmux	Everything around the agent. The terminal comes first and everything else sits on the side, a wrong path in its output leads nowhere, and an agent starts wherever your shell happens to be.

Tiri gives up none of these.

Change anything by asking

Everyone works differently, so Tiri is yours to change. Not a setting, and not a plugin API: you change the actual source.

1. Choose Change Tiri…, point at anything and say what you want instead.
2. Your own agent edits Tiri's source, on your own subscription.
3. Press Try It. Tiri reopens in about half a second, and your agents keep running.
4. Keep the change, or go back in one click.

• Anything: layout, behavior, shortcuts, what a button does, or a feature Tiri doesn't have yet.
• It lasts: every update keeps your changes. If Tiri ships the same thing, your change retires itself.
• It's safe: your agent can build a change, but only you can switch to it. Plain Tiri is always one click away.

Any path an agent prints opens in place

• ⌘-click a path in agent output, and the file floats over the session without moving your layout. This is the Peek.
• Even a wrong path opens. Tiri finds what the agent meant, or lets you choose.
• Your agent can open things too. tiri open report.md floats what it made for you to read, and your keyboard stays in the session.
• Undo or Ask on any change goes to the agent that made it, typed into its input and waiting for your Return.

What you keep

• Your agent, untouched. It's the real CLI, with your config, hooks and subscription.
• Any agent. Claude Code, Codex, Grok, or any command you add.
• Your muscle memory. Shortcuts, the explorer and workspaces work like Cursor and VS Code.
• Your Git workflow. Agents work in your repo, and Tiri finds the branches they make.
• Your servers. Connect over your own SSH config, with one 90 KB helper and no root.
• Your setup, for good. No account, no cloud of ours, and an MPL-2.0 license.

What you get

• Every agent at a glance: what each one is doing, and which one needs you.
• Write to your agent in a real box. ⌘↩ opens it at the terminal's foot, for words, pictures, files and long pastes. If the agent asks something meanwhile, your message waits.
• Files, diffs and pages are tabs, equal to terminals. There's no terminal drawer.
• Agents outlive the app. Quitting, crashing or a dropped server connection doesn't stop them.
• Your dev servers in one place. ▶ Start runs each workspace's servers and start scripts, and every agent uses the same ones, so none starts a second copy.
• Folder first: nothing starts until you say where, so an agent never works in the wrong place.
• Per-turn diffs show what one prompt changed.
• Notes on anything: point at a spot on a picture or PDF, an element of a page, or click the + beside a line, and say what's wrong. Notes collect across files and go to the agent with your message.
• ⌘L quotes a selection to your agent, as a real mention in Claude Code.

What Tiri believes

• The agent types, and you read and judge. Everything serves reading first, so there's no AI ghost text.
• No AI of its own. Tiri sells nothing, promotes nothing and never nags.
• People don't operate Git; agents do. Fetch, pull and push take one click. Anything beyond that is a request to an agent.
• Nothing goes to an agent without your say-so. Notes, Undo and Ask wait until you send them.
• Never interrupt. Alerts never reorder your tabs, and Esc on a Peek never reaches the agent.
• Whatever you can do, an agent can do through the tiri command.
• Settings have two ways in: the screen and your agent. You never edit a JSON file.
• Don't rebuild the agent. Skills, hooks and MCP stay with your agent. Plugins only add what a terminal can't draw.
• Native and fast. Built in Swift, with no Electron. Features are never dropped for speed.

When to use something else

• For cloud sandboxes or a task board, use an agent manager.
• If you type code all day, use an editor. Tiri is built for reading and reviewing.
• On Windows, Linux or an Intel Mac. Tiri needs macOS 26 on Apple silicon.

Install

Download Tiri, or use Homebrew:

brew tap tiri-build/tap
brew install --cask tiri-build/tap/tiri

Tiri needs macOS 26 on Apple silicon. Pick an agent and choose a folder. Say yes when Tiri offers to install hooks.

To build it yourself, you need the Command Line Tools (xcode-select --install) or Xcode 26:

./build.sh && open build/Tiri.app
