Terminal Deck

Terms

Terminal Deck is free software under the MIT licence. You may use it, copy it, change it and ship it in your own products. It comes with no warranty of any kind, and what your agents do on your machine is your responsibility.

These terms are written in plain language. Where they and the MIT licence text differ, the licence in the repository is the one that governs.

Last updated 14 August 2026 · applies to version 0.1.2

The licence

The app is licensed under the MIT licence, as recorded in the project's package.json and published in the source repository. In practice that means you may use it commercially, modify it, distribute it and include it in closed-source work, provided the copyright notice and the licence text travel with any substantial portion of the code you redistribute.

There is no separate commercial licence, no per-seat term and nothing to buy. Nothing on this site creates a subscription or an ongoing obligation in either direction.

No warranty. Provided as-is.

The software is provided "as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose and non-infringement. It is not certified, audited or guaranteed for any use, and no promise is made that it is free of defects, that it will keep working, or that any particular version will ever be released.

Version 0.1.2 is an early build. Neither package is signed — the macOS one is not notarised either — the macOS build runs only on Apple silicon and the Windows build only on x64, and nothing is ever pushed to you: on macOS the app can check for a new version and install one you accept, and on Windows that path has never been exercised, so treat updating as something you do yourself.

Back up your work. This app runs coding agents that edit files. Use it on projects under version control, with a clean working tree you can return to. That is good practice with any agent, and it is the only recovery mechanism either the agent or this app gives you.

You are responsible for what the agents do

This is the clause that actually matters, so it gets its own section rather than a line in a list.

Terminal Deck spawns real agent CLIs as subprocesses on your machine, with your user account's permissions and your login shell's PATH. It does not sandbox them, does not confine them to the project folder, does not review or filter their actions, and does not ask you to confirm anything they do. Whatever those agents can do in your own terminal, they can do here — including in a session you are not currently looking at.

Anything an agent writes, deletes, commits, pushes, installs, publishes or spends is your responsibility. Any permission you grant, hook you install, MCP server you connect or command you let an agent run is your decision. So is running an agent in a folder you cannot afford to lose.

You are also responsible for using it lawfully, and for the code you produce with it — including whether that code may be used where you intend to use it.

Third-party software and its terms

Terminal Deck runs programs it does not ship, does not bundle and does not modify. Each one is yours, installed by you, signed in by you, and governed by its own terms and pricing — not by these.

  • Claude Code — Anthropic's terms and usage policies apply to your account and your usage.
  • Codex CLI — OpenAI's terms apply.
  • Gemini CLI — Google's terms apply.
  • git, the gh CLI, and any MCP server you configure — their own licences apply, and any repository or service they reach is governed by that service's agreement with you.

Any charge from those providers is between you and them. Terminal Deck cannot stop an agent from spending money and does not try to.

Cost figures are an estimate, not a bill

The cost display is computed locally, by multiplying the token counts in Claude Code's transcripts against a built-in table of published Anthropic list prices captured on a date recorded in the source. It exists so you can see the shape of your spending. It is not an invoice, it is not read from your account, and it will not match your bill — a subscription plan, an enterprise agreement, promotional pricing, or a model served through Bedrock or Vertex are all priced differently and are deliberately not modelled. A model with no published rate shows no cost rather than a guess, and historical rates are flagged as such. Treat the number as an indicator and your provider's own billing as the truth.

Limits of liability

To the fullest extent permitted by law, the author is not liable for any claim, damages or other liability arising from the software or its use — including lost or damaged data, lost work, lost profits, service interruption, costs incurred with an agent provider, or anything an agent did while running inside this app — whether in an action of contract, tort or otherwise, and whether or not the possibility of such damage had been raised.

Some jurisdictions do not allow certain warranties to be disclaimed or certain liabilities to be excluded. Where that is the case, the disclaimers above apply to the maximum extent that jurisdiction permits, and nothing here removes a right you cannot legally waive.

Support, changes and the rest

There is no support obligation

This is a project maintained by one person and given away. Issues and pull requests are welcome at the issue tracker, and nothing on this site promises a reply, a fix, a timeline or a future release.

Changes to these terms

These terms may change. The date at the top is the last edit, and every version is in the repository's history. A change applies to the version of the app you download after it; it cannot reach back and alter the licence under which you already received a copy, because that licence came with the copy.

Trademarks and names

Claude, Claude Code, Codex, Gemini, GitHub and macOS are the marks of their respective owners, used here only to say truthfully what this app works with. This project is not affiliated with, endorsed by or sponsored by Anthropic, OpenAI, Google, GitHub or Apple.

Privacy and security

The app collects nothing, and the privacy page sets out exactly what is stored on your machine and what reaches the network. The security posture, its stated limits, and how to report a vulnerability are on the security page.
