The Mac terminal for AI coding agents

Flintty.

flint + tty, the terminal that strikes the spark.

Run your agents side by side and see at a glance which one is working, which is done and which needs you. Tabs in a sidebar, Spaces, splits and a command palette, native on your Mac.

Free · Apple Silicon · macOS 13 or later

This isn't
a screenshot.

One agent is working, one needs you, one is done. Click the tabs; open "claude · docs" and its Done goes away. Point at "api" and fold its sub-tabs. Open the command palette. Pick a theme further down and watch it change.On a wider screen you can click through its sidebar, panels and themes.

Work
Built for AI agents

Let the agents work.
You keep watch.

See which agent needs you.

Every tab says what its agent is doing, right in the sidebar. No spinners, nothing blinking: one tag asks you to act.

Working. Three still dots while it runs.
Needs you
Waiting for an approval or an answer. It stays until you answer; point at the tab to see the question.
Done
Finished while you looked elsewhere. It goes away when you open the tab.

A Space you're not in gets a small pip on its dot, and the Dock icon counts the agents waiting for you.

Needs you and Done work with Claude Code, with nothing to set up. With other agents, like Codex, Gemini or Aider, the tab shows while it's busy. The agent tells Flintty through an escape sequence, so nothing leaves your Mac.

Side by side

Two agents and your dev server in one tab.

⌘D

A vault for your keys

Secrets behind Touch ID, pasted only where you choose.

⌃⌘V

A nudge when you're away

Optional, off by default: a notification only while you're in another app. Click it to jump to the tab.

Pins bring agents back

One click reopens every pane and restarts claude --continue.

Type once, run everywhere

One command on every server at once.

⌥⌘I

Tabs inside tabs

Keep an agent, its server and its logs under one tab.

⌥⌘T
Skills

Teach it
what to notice.

A skill is a small text file. Say what to find or what to watch, and what to offer. Flintty decides how it looks. No code, no build. ⌃⌘E opens the panel.

Keyboard first

The mouse
is optional.

Every action is in the command palette and the menu bar. And the line you type edits like a Mac text field: click to move the cursor, ⌥⌫ deletes a word.

Themes and plugins

Make it yours.

Each Space has its own theme. Pick one and the window beside it changes, and so does the one at the top of the page. 13 come built in and 14 more are a click away in the Store (⌥⌘P), or write your own as one small file.

FAQ

Straight
answers.

Is it free?
Yes, free during the beta, with no account. When paid plans arrive, the core terminal stays free, and beta users hear first and get a thank-you.
How is it different from iTerm2, Ghostty or Warp?

Today more of the work happens in the terminal: commands, servers, SSH, and now coding agents, often several at once. Flintty is a terminal built for that kind of day.

Tabs live in a sidebar, grouped into Spaces per project, with splits, notes, quick commands, a vault for your secrets, and skills that spot things on screen. And when you run agents, each tab shows if it's working, done or needs you, so you never hunt for the one waiting on you.

Does it send my code to an AI?
No. Flintty has no AI of its own. The agents you run, like Claude Code or Codex, work as they do in any terminal, with your own account.
What does it collect?
Nothing you type or see. The app sends one thing: a daily check for updates, carrying only the Flintty version. No account, no ID, nothing about what you do. Anything more will be off until you turn it on. The website counts visits without cookies. Privacy page
Which agents does it work with?
All of them. Any agent runs in Flintty, and its tab shows while it's busy. Claude Code goes further: its tab tells you when it needs your approval and when it's done, with nothing to set up.
Will it run on my Mac?
On any Mac with Apple Silicon (M1 or later) and macOS 13 Ventura or later. Intel Macs aren't supported.
Will my shell setup still work?
Yes. Flintty runs your usual shell with your own startup files. Its extras hook into zsh; other shells work with fewer extras.
Is it open source?
No. The open-source parts it uses are credited in the app under Acknowledgements.
