-T3 Code is an "agent harness control surface". It enables control of the agents on your machine with a best-in-class mobile app ([iOS](https://apps.apple.com/us/app/t3-code-remote-claude-more/id6787819824), [Android](https://play.google.com/store/apps/details?id=com.t3tools.t3code)), [web app](https://app.t3.codes) and [Electron-based desktop app](https://t3.codes).
+<h1 align="center">T3 Code</h1>
 
-Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, OpenCode, Google Antigravity, and fx. If they're set up on your computer, T3 Code can control them.
+<p align="center">The open-source control plane for coding agents.</p>
 
-## "Wait, what are you selling me?"
-
-Nothing. We built T3 Code because we wanted the best possible development experience with agents. We were inspired by existing solutions like the Codex desktop app, Conductor, Claude Desktop and Cursor Glass, but none met our bar.

+  </a>
+</p>
 
-## Installation
+T3 Code runs the coding agents on your machine and gives them one fast interface. Start a thread at your desk, then approve the next step from your phone.
 
-> [!WARNING]
-> T3 Code currently supports Codex, Claude, Cursor, Grok Build, OpenCode, Antigravity, and fx. Install and authenticate at least one provider before use:
->
-> - Codex: install [Codex CLI](https://developers.openai.com/codex/cli) and run `codex login`
-> - Claude: install [Claude Code](https://claude.com/product/claude-code) and run `claude auth login`
-> - Cursor: install [Cursor CLI](https://cursor.com/cli) and run `agent login`
-> - Grok Build: install [Grok Build CLI](https://x.ai/cli) and run `grok login`
-> - OpenCode: install [OpenCode](https://opencode.ai) and run `opencode auth login`
-> - Antigravity: enable it in Settings, then use **Install Antigravity** and **Sign in with Google**. No CLI is required.
-> - fx: install [fx](https://fx.sh) and run `fx login` on the machine running the T3 Code server ([setup guide](./docs/user/providers-fx.md))
+It works with Claude Code, Codex, Cursor, OpenCode, Grok Build, Antigravity, Kiro, Pi, Muse Code, fx, and any [ACP](./docs/user/providers-acp.md) agent. If an agent is set up on your computer, T3 Code can control it.
 
-### Command line
+## What you get
 
-```bash
-curl -fsSL https://t3.codes/install.sh | sh
-```
+- **Your subscriptions.** T3 Code does not resell tokens. It drives the agents you are already signed in to.
+- **Every agent in one place.** Change models in the middle of a thread. Let Claude hand a task to Codex.
+- **Desktop, web, and phone.** One server, and every client shows the same threads. There are apps for iOS and Android.
+- **Remote ready.** Run agents on any machine. Connect over your local network, Tailscale, or [T3 Connect](./docs/user/remote-access.md).
+- **Git built in.** Each thread can work in its own worktree. Review the diff, then commit, push, and open a pull request with one button.
+- **Fast.** Performance is a feature here. We measure it, and we treat a dropped frame as a bug.
+- **Open.** MIT licensed. If you don't like something, fork it.
 
-On Windows, in PowerShell:
-
-```powershell
-irm https://t3.codes/install.ps1 | iex
-```
-
-Then run `t3` to start the server and open the local web app. `t3 service install` keeps it running in the background, `t3 update` moves to a newer release, and `t3 --help` has the full reference.
-
-To try it once without installing, run `npx t3@latest`. It offers to install the `t3` command for you.
+## Install
 
 ### Desktop app
 
-Install the latest version of the desktop app from [GitHub Releases](https://github.com/pingdotgg/t3code/releases), or from your favorite package registry:
+[Download T3 Code](https://t3.codes/download) for macOS, Windows, or Linux. You can also use a package manager:

-```
-
-#### Debian, Ubuntu (`.deb`)
+### Command line
 
-Download the `.deb` from [GitHub Releases](https://github.com/pingdotgg/t3code/releases), then:
+This installs the `t3` command. Run `t3` to start the server and open the web app.
 
 ```bash
-sudo apt install ./T3-Code-*.deb

 ```
 
-#### Arch Linux (AUR)
-
-Stable:
+On Windows, in PowerShell:
 
-```bash
-yay -S t3code-bin
+```powershell
+irm https://t3.codes/install.ps1 | iex
 ```
 
-Nightly:
+To try it once without an install, run `npx t3@latest`.
 
-```bash

-#### Nix (nixpkgs)
+### Sign in to an agent
 
-```bash
-nix profile add github:NixOS/nixpkgs/nixos-unstable#t3code

+T3 Code needs one agent that is installed and signed in. For example, install [Claude Code](https://claude.com/product/claude-code) and run `claude auth login`, or install [Codex CLI](https://developers.openai.com/codex/cli) and run `codex login`.
 
-The package is maintained in [nixpkgs](https://github.com/NixOS/nixpkgs/tree/nixos-unstable/pkgs/by-name/t3/t3code)
-and includes the desktop app (`t3code-desktop`) and the `t3` command.
-See [Nix installation](./docs/user/install.md#nix-nixpkgs) for NixOS configuration and updates.
+[Provider setup](./docs/user/install.md#providers) has the steps for each agent. [Install T3 Code](./docs/user/install.md) covers nightly builds, AppImage, WSL, and NixOS.
 
-## Some notes
+## "Wait, what are you selling me?"
 
-We are very very early in this project. Expect bugs.
+Nothing. We built T3 Code because we wanted the best possible development experience with agents. We were inspired by existing solutions like the Codex desktop app, Conductor, Claude Desktop and Cursor Glass, but none met our bar.
 
-We are (mostly) not accepting contributions yet. Small fixes may be considered. Big features will not be.
+We wanted something performant, remote-ready, and truly open. If we ever go the wrong direction, we want you to have everything you need to fork and build the tool that you want.

+The shell snapshot loads over HTTP, which needs only the prepared connection, so

+it before the socket and the config are ready. Two constraints follow. The live
+config stays the authority: rows loaded early for a build or with omissions that

+environment's rows stay as shown until its connection's server snapshot arrives,
+it is synchronized, or it disconnects, and environments that get there within two
+seconds of each other show together. Only an environment that is connected or on
+its first attempt, and still owes its snapshot, is waited for; a retry can take
+minutes. A move in a list is refused while its rows wait, because its plan would
+use order keys the server may have replaced. Every other row action looks up the

+row. The hold stops only changes the user

+delete, and their reverses) makes that environment's rows follow the live snapshot
+until it is live. Point reads (a
+thread's own shell, route checks) keep the live snapshot, where a row the server just
+sent must not look missing. The decision reads the snapshot's own sequence: a second
+atom derived from the same shell state can be one update behind the rows. The mobile
+splash screen also waits, for a bounded time, until every enabled environment has
