What's New — Zest CLI (Release 12/10/2026)

The first release of the Zest CLI: one command that measures your Claude Code and Codex sessions.

npx @winding-labs/zest

One-line setup. Installs the CLI, signs you in to Zest and starts collecting new Claude Code and Codex sessions in the background.
Runs with your sessions. The collector starts with each Claude Code or Codex session and stops after the last one closes. zest start keeps it running until zest stop.
Replaces the plugins. If a tool already has the Zest plugin, the installer uploads what the plugin still holds and switches it off, so no session is collected twice.
Keeps itself up to date. The CLI updates itself when a new release is out. zest update updates now; set ZEST_NO_AUTO_UPDATE=1 to turn automatic updates off.
macOS, Linux and Windows (x64). Standalone binaries, checked against the SHA256 checksums in the npm package before they run.

Useful commands: zest status, zest pause / zest resume, and npx @winding-labs/zest --uninstall to remove everything.

Only sessions started after setup are collected.
