## Which one, for what

### 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 45
- Schema & documentation, 87 against 30
- Agent ergonomics, 78 against 5
- Security & auth, 66 against 36
- Payments & pricing, 60 against 30
- Maintenance & community, 85 against 58
- Transparency & trust, 70 against 58

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

### Unstoppable (F)

Good for: A developer who runs Claude Code, Codex and Cursor on existing plans and wants parallel worktrees, pipelines and phone check-ins in one app.

Also in its favour:
- No key needed to call it
- Free to start without a card
- No incidents deducted, where OpenHands loses 5 points for them

Watch for: No API, MCP server, SDK or documented CLI for an outside agent. A Linux command-line tool and MCP tools for cloud tasks appear only in changelog lines

## Verdicts

**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.

**Unstoppable.** Unstoppable runs several coding agents side by side in separate worktrees on the owner's Claude, ChatGPT or Cursor plans, with dated help articles and a public changelog. It has no API, MCP server or documented command an outside agent can call, every chat starts in Full access, and its pages disagree on which parts need a paid plan.

## Before you call either

### 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 The `openhands --headless` CLI is no longer maintained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

### Unstoppable

1. Don't plan to drive Unstoppable from another agent. It has no documented API, MCP server or CLI. Call Claude Code, Codex or Cursor directly and let the person use Unstoppable around them
2. Inside Unstoppable, check the approval mode before acting. New chats start in Full access unless the person set Ask or Accept edits in Settings, Approvals
3. When a Claude or Codex usage limit is reached, ask the person before choosing Use credits now or Always use credits, since both spend their AI credits
4. Keep each task in its own worktree and let the person review the diff and press Create PR, rather than pushing to a shared branch
