## Which one, for what

### Antigravity CLI (C)

Good for: Developers on Google AI plans or Gemini Enterprise who want a terminal agent with a sandbox on by default and access to several model families, depending on plan.

Also in its favour:
- No incidents deducted, where OpenHands loses 5 points for them

Watch for: Closed source. The repository holds the README, changelog and examples, with no source and no licence file

### OpenHands (BB)

Good for: Teams that want to self-host a coding agent with a web UI, per-conversation Docker sandboxes and scheduled or webhook automations, or embed the agent through a Python SDK and REST API.

Ahead on:
- Reliability, 83 against 43
- Schema & documentation, 87 against 78
- Security & auth, 66 against 53
- Payments & pricing, 60 against 30
- Maintenance & community, 85 against 68
- Transparency & trust, 67 against 54

Also in its favour:
- Agent-ready, a grade of BB or better
- Open source

Watch for: Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem

## Verdicts

**Antigravity CLI.** Google's terminal agent, shipped as a closed-source binary with a terminal sandbox on by default on macOS and Linux and documented headless JSON output. Interactions are used to improve Google products unless users opt out, and a headless run exits 0 when a tool is denied.

**OpenHands.** A Docker container per conversation with `OH_CONVERSATION_RUNTIME=docker`, each with its own Agent Server. Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem.

## Before you call either

### Antigravity CLI

1. Read the `status` field from `--output-format json` and read stderr too. A tool refused for lack of approval still exits 0
2. Pre-approve each shell command and tool a headless run needs with `action(target)` rules under `permissions.allow` in ~/.gemini/antigravity-cli/settings.json, because headless runs cannot ask
3. Export `GEMINI_API_KEY` after setting modelProvider to gemini. The CLI won't start when the key is missing, and setting the variable alone has no effect
4. Turn off Enable Telemetry in the Account settings before running on private repositories if Interactions should not be used for product improvement
5. Set `--print-timeout` explicitly. The docs give a five-minute default, while `agy --help` shows 0s

### OpenHands

1. Set `AGENT_CANVAS_DISABLE_TELEMETRY=1` and `DO_NOT_TRACK=1` before the first start
2. Start Canvas with `OH_CONVERSATION_RUNTIME=docker` or use the Docker image. The npm install runs the agent on the host
3. Turn on confirmation mode with a risk threshold. Canvas starts with it off
4. Use the SDK or the Agent Server API for headless runs. The `openhands --headless` CLI is no longer maintained
5. Set `filter_tools_regex` on the agent to keep unneeded MCP tool definitions out of the context
