You can launch T3 Code and configure providers afterwards. ## Command line ```bash curl -fsSL https://t3.codes/install.sh | sh ``` On Windows, in PowerShell: ```powershell irm https://t3.codes/install.ps1 | iex ``` This puts `t3` in `~/.local/bin`. If your shell reports `command not found` afterwards, that directory is not on your `PATH` yet; the installer prints the line to add. Set `T3CODE_CHANNEL=nightly` to install the nightly train, or `T3CODE_VERSION` to pin an exact version. | Task | Command | | ------------------------------------------------ | --------------------------------------------------------- | | Start the server and open the web app | `t3` | | Start the server without a browser | `t3 serve` | | Keep it running in the background (macOS, Linux) | `t3 service install` ([details](./background-service.md)) | | Move to the newest release | `t3 update` | | Remove it again | `t3 uninstall` | Run `t3 --help` for the full reference. To try T3 Code once without installing it, run `npx t3@latest` instead (needs Node.js for `npx`). ### Intel Macs There is no `t3` executable for Intel Macs (the desktop app is available). To run a server there, build it from source with Node.js 24 and `vp` ([Install vp](https://github.com/pingdotgg/t3code#install-vp)): ```bash git clone https://github.com/pingdotgg/t3code cd t3code && vp i && vp run build:desktop node apps/server/dist/bin.mjs ``` `t3 update` and the background service do not apply to a server run this way; update it with `git pull` and a rebuild. ## Desktop app Download a release from [GitHub Releases](https://github.com/pingdotgg/t3code/releases), or use a package manager: | Platform | Install | | ------------------ | ---------------------------------- | | Windows | `winget install T3Tools.T3Code` | | macOS | `brew install --cask t3-code` | | Debian, Ubuntu | `sudo apt install ./T3-Code-*.deb` | | Arch Linux | `yay -S t3code-bin` | | Arch Linux nightly | `yay -S t3code-nightly-bin` | The `.deb` updates itself like the other desktop builds. It asks for your password to install each update. If your desktop has no password prompt, the update fails. Download the new `.deb` and install it the same way. ### Windows Subsystem for Linux Choose a WSL distro in **Settings → Connections** to run agents and projects there. Install the provider CLIs inside that distro. T3 Code installs its own server runtime there automatically; the first launch after an app update can take longer. ### Open a project from a terminal With the desktop app already running on the same machine: ```bash t3 app ``` This opens a new thread for the current directory, adding the project if needed. Pass a path, such as `t3 app ../my-project`, to open another directory. It requires the desktop app, so a standalone server or an SSH session is not enough. If the command cannot reach the app, start or update the desktop app and try again. ## Mobile app Install T3 Code from the [App Store](https://apps.apple.com/us/app/t3-code-remote-claude-more/id6787819824) or [Google Play](https://play.google.com/store/apps/details?id=com.t3tools.t3code). The phone connects to a server on another machine. Follow [remote access](./remote-access.md) to link it through T3 Connect or a pairing URL. If the app crashes during launch, open Settings → Diagnostics on the next launch that succeeds. It lists startup crashes from the last 7 days with the error and component stack that store crash reports leave out. Copy the report and paste it into a GitHub issue. Error messages can quote values from the app, so read it over before sharing. ## Providers Open **Settings → Providers** in the web or desktop app, select the environment, and enable the provider you want. Installation, login, and configuration belong to that environment's machine, even when you connect from a phone or another computer. | Provider | Install and authenticate | | ----------- | -------------------------------------------------------------------------------------------- | | Codex | Install [Codex CLI](https://developers.openai.com/codex/cli), then run `codex login`. | | Claude | Install [Claude Code](https://claude.com/product/claude-code), then run `claude auth login`. | | Cursor | Install [Cursor CLI](https://cursor.com/cli), then run `agent login`. | | Grok Build | Install [Grok Build CLI](https://x.ai/cli), then run `grok login`. | | OpenCode | Install [OpenCode](https://opencode.ai), then run `opencode auth login`. | | Antigravity | Install and sign in with Google from T3 Code's provider settings. | Provider CLIs must be on the server's `PATH`. If T3 Code cannot find one, set its **Binary path** in provider settings, especially when using a version manager. Cursor's executable is `cursor-agent`, although its login command is `agent login`. Antigravity can use its managed runtime without a `PATH` entry. T3 Code warns when a provider version has known compatibility problems with your release. Check **Settings → Providers** on that environment for the recommended version or range. When its package manager supports installing a specific version, you can install the recommendation there. Otherwise use the provider's installer on the environment's machine. An unlisted version is unverified. When a provider CLI is behind its latest release, its provider card shows the available version. **Update now** appears only when T3 Code can tell which installer owns the CLI (its own update command, Homebrew, or a global npm, pnpm, bun, or Vite+ install) and runs that installer. Otherwise update the CLI the same way you installed it. Homebrew installs compare against the version Homebrew offers, which can trail the npm release by a few hours. Add another provider instance for a separate account or configuration. Each instance can have its own environment variables, such as API keys or a custom base URL. Mark secret values as sensitive; after saving, T3 Code does not display their original values. For provider-specific setup and accounts, see [Codex](./providers-codex.md), [Claude](./providers-claude.md), [OpenCode](./providers-opencode.md), and [Antigravity](./providers-antigravity.md). ## Next steps - [Working with threads](./thread-sidebar.md): start tasks and organize parallel work. - [Permission modes](./permission-modes.md): choose when agents ask before acting. - [Remote access](./remote-access.md): connect from another device. - [Running in the background](./background-service.md): keep a Linux or macOS host available. - [Updating T3 Code](./updating.md): update the app and connected servers. ````
