Zest CLI

Measure your AI coding sessions with Zest. One command installs the Zest plugin of each AI coding tool you pick (Claude Code, Codex, Grok Build, Hermes, opencode, Freebuff):

npx @winding-labs/zest

In a terminal it runs as a short guided setup: pick your tools (the ones found on your machine are preselected) and it installs their plugins. Skip the questions with:

• --yes — install the plugins of the detected tools without asking
• --only=claude,codex,grok,hermes,opencode,freebuff — install only the tools you list

It works on macOS, Linux and Windows (x64) and needs Node.js 18 or newer for the installer only. The CLI itself is a standalone binary in ~/.zest/bin/zest (%USERPROFILE%\.zest\bin\zest.exe on Windows, added to your user PATH — open a new terminal afterwards), verified against SHA256 checksums shipped in the npm package.

Each plugin signs in once inside its tool; the installer prints the command. Only sessions started after setup are collected.

• zest status — your Zest plugins per tool: sign-in, sync, last sync and errors; --watch keeps it live, --json prints it as JSON
• zest update — install the latest release
• zest pause / zest resume — stop or restart uploads
• zest logout — sign this device out, also on the Zest server; the web app, your plugins and other devices stay signed in
• npx @winding-labs/zest --uninstall — stop collecting, remove the hooks, shims and the binary and sign out; the Zest plugins stay installed (it offers to turn back on any plugin the CLI replaced)

zest enable <tool> --replace-plugin moves a tool from its plugin to the CLI's own collector. That is an invite-only test: without it the command switches nothing. Where it is on, the CLI also updates itself; set ZEST_NO_AUTO_UPDATE=1 to turn that off.

Binaries for each release are attached to this repository's releases.
