W&B HiveMind

W&B HiveMind is a shared dashboard for AI coding sessions. A lightweight daemon runs on each developer's machine, watches for coding agent activity, and sends session transcripts to hivemind.wandb.tools.

Coding agents like Claude Code, Codex, Cursor, Gemini CLI, OpenCode, GitHub Copilot CLI, and Pi all write transcripts to the local filesystem as they work. The HiveMind daemon wakes up every 30 seconds, checks for new activity, and uploads anything it finds. There's nothing to configure per agent. If the agent writes transcripts, HiveMind picks them up.

This repository hosts release binaries for the HiveMind daemon and is the public issue tracker. Found a bug or have a feature request? Open an issue. The dashboard and docs live at hivemind.wandb.tools.

Getting started

Install the client and start the daemon. hivemind start registers a background service (launchd on macOS, systemd on Linux) so the daemon keeps running and starts on login, prompting you to authenticate through GitHub or your organization's SSO if you haven't already.

Install (macOS or Linux)

curl -fsSL https://hivemind.wandb.tools/install | sh
hivemind start

The one-line installer is the recommended path. On an Apple Silicon Mac with Homebrew it installs the wandb-hivemind cask, so you get a clean brew uninstall later; everywhere else it downloads the signed binary to ~/.local/bin — no Homebrew, Python, or sudo required. Either way the daemon detects and applies upgrades automatically.

To skip the cask and always install the raw signed binary — even on a Homebrew Mac — pass --binary:

curl -fsSL https://hivemind.wandb.tools/install | sh -s -- --binary

On macOS the binary requires Apple Silicon; on an Intel Mac, use uv (below). For fleet rollouts through an MDM, see Deploying with MDM.

macOS (Homebrew cask)

Prefer to drive the install through Homebrew yourself? Install the cask directly:

brew install wandb/taps/wandb-hivemind
hivemind start

Homebrew 6 requires third-party taps to be trusted before their code runs. Installing by fully-qualified name records that trust automatically (you'll see Trusted cask wandb/taps/wandb-hivemind on first install); review or revoke it later with brew trust / brew untrust.

The cask installs the same self-updating binary, so there's nothing to upgrade by hand — brew upgrade is a no-op for it unless you pass --greedy. The cask is Apple Silicon-only; on an Intel Mac, use uv below.

Any platform (uv)

uv tool install wandb-hivemind
hivemind start

uv installs the cross-platform Python package — the path for Intel Macs and Windows, where the one-line installer and cask don't apply. Upgrade with:

uv tool upgrade wandb-hivemind

Uninstalling

How you remove HiveMind depends on how it was installed. Since the one-line installer uses the cask on an Apple Silicon Mac with Homebrew, check whether brew owns it:

brew list wandb/taps/wandb-hivemind

If that succeeds, uninstall through brew with --zap — this stops and unregisters the launchd service, removes the binary, and clears the leftover LaunchAgent plist and logs (it deliberately leaves ~/.hivemind alone — see below):

brew uninstall --zap wandb/taps/wandb-hivemind
