witness for Mac
The same projects and cards as witness.nu, and agent sessions that run on your Mac with your own Claude Code or Codex.
Install it
Open the file and drag witness to Applications. Then open witness and press Sign in using your browser; it is the same account as witness.nu.
What it does on your Mac
witness is signed by Robin Smedberg AB and notarized by Apple. It runs as you: it installs nothing that runs in the background, and it never asks for your password.
The app talks to witness.nu. A session runs your own Claude Code or Codex, signed in with your own accounts, on repositories in a folder you choose.
Updates download in the background from witness.nu, which sends the app on to GitHub for the file. Each one is checked against a key built into the app before it installs, and installs when you press Restart to update.
It asks macOS for one exception to its strictest settings: permission to compile code as it runs. The two programs inside the app that connect to Claude Code and Codex are built with Bun, which needs it.
