Manage many projects with the hub

The master hub is one installable web app that manages every insight-flow project on your machine. From a single page you switch between projects, open a running one, start a stopped one, and create new ones — all on one origin (http://localhost:6100), which is what makes it installable as a PWA and usable from your phone.

For the full reference (endpoints, config, registry, security model) see Master hub. This guide is the walkthrough.

1. Start the hub​

Most of the time you don't start it by hand — launching any project dashboard auto-starts it:

insight-flow ui            # project dashboard on :6006; auto-starts the hub on :6100

To run it explicitly (e.g. as a long-lived process), or from a folder with no project:

insight-flow master                # → http://localhost:6100/overview
insight-flow master --port 6200    # custom port
insight-flow                       # in a NON-project folder → opens the hub

Open http://localhost:6100/overview to see the switcher.

2. Register your projects​

A project shows on the hub once it's registered. The easiest ways:

  • When you init — answer "register with the hub?" (or pass --register-hub).
  • From the hub — the + New project modal registers by default.
  • Automatically — running insight-flow ui in a project self-registers it.

Registrations persist in ~/.insight-flow/hub.json, so your projects are still listed after a restart (they show as stopped until their dashboards run).

// taskflow.config.json — a project's link to the hub (all optional)
{
  "master": {
    "url": "http://localhost:6100",
    "port": 6100,
    "startMasterLocally": true, // auto-spawn the hub if none is running
    "standalone": false          // true → this project never registers
  }
}

3. Open, start, and switch​

On the overview, projects are split into Running and Stopped:

  • Running → Open → takes you to that project's dashboard at http://localhost:6100/project/<id>/ — served through the hub, same origin, so the ⌂ Hub link brings you back.
  • Stopped → Start → spawns the dashboard and drops you into it once it's live.
  • ↻ Refresh re-checks which projects are up.

4. Create a new project from the browser​

Click + New project:

  1. Browse to a parent folder (a server-side folder browser).
  2. Name it.
  3. Pick install options — task lifecycle events (on), agent activity tracking (off), composer-authoring flow (off), register with the hub (on), and the editor (Claude / Cursor / all).

The hub scaffolds the folder, runs init, and adds it to the switcher.

5. Install it as an app (and use it on your phone)​

Because it's a single origin, your browser can install the hub as a PWA (look for "Install app"). Installed, it's one icon that switches between all your projects, with desktop/OS notifications when a task changes status or Claude finishes / needs permission — even while backgrounded.

To reach it from your phone or another device on the LAN, allowlist the machine's address:

INSIGHT_FLOW_TRUSTED_HOSTS=192.168.0.77 insight-flow master --port 6100
# on the phone (same Wi-Fi): http://192.168.0.77:6100/overview  → then "Install app"

The hub prints a LAN: URL for each allowlisted host on startup.

Trust boundary

INSIGHT_FLOW_TRUSTED_HOSTS means "trust this network." With it set, any device on the LAN that reaches the port can create and start projects on the hub host. Use it only on networks you trust; leave it unset (localhost-only) on shared Wi-Fi.

Legacy bulk-*​

The older bulk-register / bulk-ui / bulk-down commands still work and their entries fold into hub.json, but the hub above is the recommended path.

insight-flow bulk-ui --add "web-app" /path/to/web-app   # register by path (legacy)
insight-flow bulk-ui                                    # multi-select launcher (legacy)
insight-flow bulk-down                                  # stop what the last bulk-ui started
