Install

The current public release is v1.3.6.

Windows: install Desktop

1. Open Download and download the Windows x64 MSI.
2. Run the installer and open Pytxo Desktop. The beta installer is not code-signed yet, so Windows SmartScreen may say it does not recognize the app: choose More info, check that the file came from pytxo.com, then Run anyway. Updates inside the app are signed and verified before they install.
3. Install and sign in to your coding agents separately. Desktop runs Codex, Claude Code, Cursor Agent, OpenCode and Antigravity.

Desktop includes its local Pytxo core. You do not need to install the Pytxo CLI unless you want terminal commands, MCP, or pytxo doctor.

Continue with Desktop setup. There is no current macOS or Linux Desktop installer.

Install the CLI

For Windows, macOS, or Linux with Node.js 18 or newer:

npm i -g pytxo@1.3.6
pytxo --version
pytxo doctor

npm i -g installs a small launcher. The first pytxo command downloads the matching native binary and checks it against the release's SHA-256 list; later commands start the binary directly. npm 12 and pnpm 10 block install scripts by default, so npm prints an install-scripts warning about pytxo's postinstall. You can ignore it. Package managers that still run install scripts fetch the binary during install instead.

If the user who runs pytxo cannot write to the global npm folder (a root-owned prefix, or a container image), fetch the binary at install time:

npm i -g --allow-scripts=pytxo pytxo@1.3.6

You still need your own coding agent; Pytxo does not include a model subscription.

Without Node.js

Windows (PowerShell):

irm https://raw.githubusercontent.com/Pytxo-dev/pytxo-releases/main/install.ps1 | iex

macOS or Linux:

curl -fsSL https://raw.githubusercontent.com/Pytxo-dev/pytxo-releases/main/install.sh | bash

To pin the shell installer to v1.3.6, pass the version to bash:

curl -fsSL https://raw.githubusercontent.com/Pytxo-dev/pytxo-releases/main/install.sh | PYTXO_VERSION=v1.3.6 bash

You can also download a binary from GitHub Releases, place it on your PATH, and run pytxo --version.

Before your first run

Use a Git repository with working build or test commands. Review folder trust before allowing execution.

Since 1.3 the CLI covers the whole loop on every platform: plan and run work, pytxo review and pytxo apply a finished run, and pytxo land branches from any agent tool.
