Which one, for what

CLI Manager B

Best for A developer on macOS who runs several coding agents and wants another agent to start and watch sessions where the person can see and step in.

Ahead on

  • Payments & pricing, 60 against 20

Also in its favour

  • Free to start without a card
  • No incidents deducted, where Gemini CLI loses 5 points for them

Watch for

Once switched on, the API can read, type into and close every session in the app, including the user's own

Gemini CLI B

Best for Teams with a paid Gemini API key, Vertex AI credentials or existing Code Assist Standard or Enterprise licences that want an open-source harness with documented headless output.

Ahead on

  • Schema & documentation, 93 against 87
  • Agent ergonomics, 78 against 63
  • Security & auth, 67 against 58
  • Maintenance & community, 88 against 62
  • Transparency & trust, 89 against 54

Watch for

Sandboxing is off by default, and the default macOS profile allows network

Verdicts

CLI Manager

An agent can open visible terminal sessions, type into them, wait and read the screen through 12 typed MCP tools or a documented REST API, and the user can take any session back. The API reaches every open session once enabled, the app runs only on macOS, and none of the last 35 CI runs on the main branch passed.

Gemini CLI

Apache-2.0, with 16 stable releases since 3 July and documented headless output. Google sign-in for individuals ended on 18 June 2026, and the README still advertises a free tier. Sandboxing is off by default, and the default macOS profile allows network.

Before you call either

CLI Manager

  1. Ask the user to switch on Settings > Agents > AI Control API first, then read the URL and token from ~/.climanager/control-api.json
  2. On 409 awaiting_input, read the screen and answer with keys such as ["down","enter"]. Leave folder-trust and permission choices to the user
  3. Stop using a session on 409 disconnected. The user took it back
  4. Treat timedOut: true from wait as still running, not as a failure, and wait again
  5. Pass ephemeral: true when opening a scratch or worktree folder, and close only sessions you opened

Gemini CLI

  1. Set GEMINI_TRUST_WORKSPACE to true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own
  2. Turn on the sandbox with -s or tools.sandbox, and pick a proxied Seatbelt profile on macOS to cut network
  3. Set privacy.usageStatisticsEnabled to false to stop usage statistics
  4. Since 0.63.0, plans run without interactive confirmation in non-interactive mode, so set the approval mode explicitly before a headless run
  5. Authenticate with a paid Gemini API key or Vertex credentials. A Google sign-in works only for Code Assist Standard or Enterprise licences

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
