## Which one, for what

### OpenCode (B)

Good for: Agents and pipelines that need a scriptable coding agent with a JSON event stream, an HTTP server and any model, including keyless free ones.

Ahead on:
- Reliability, 72 against 60
- Payments & pricing, 60 against 50
- Maintenance & community, 81 against 74
- Transparency & trust, 71 against 59

Also in its favour:
- No key needed to call it

Watch for: Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox

### OpenMausBot (B)

Good for: A person or an outside agent who wants several CLI agents (Claude Code, Codex, Grok, ACP CLIs) organised as named bots with their own computers, routines and approvals, driven by MCP or a CLI.

Also in its favour:
- Runs on your own machine

Watch for: New bots start at Full access, which approves provider permission requests without a card

## Verdicts

**OpenCode.** Runs with no key or account on free OpenCode Zen models. Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox.

**OpenMausBot.** A bounded 20-tool MCP server with typed schemas, annotations and idempotent sends, and a headless CLI with JSON output and exit codes, let another agent hand work to a bot team and wait on it. New bots start at Full access, so provider permission requests pass without a card, and usage analytics stay on until switched off.

## Before you call either

### OpenCode

1. Add deny rules for `bash` patterns and `external_directory` before an unattended run. Most tools default to allow
2. Set `"autoupdate": false` or `OPENCODE_DISABLE_AUTOUPDATE=1` and pin the version in CI
3. Configure a provider key. With none, prompts go to free Zen models that may train on them
4. Set `OPENCODE_SERVER_PASSWORD` before `opencode serve`. Without it the server runs unauthenticated
5. Install `opencode-ai` for the 1.x server API and SDK. After `opencode upgrade --major`, use `@opencode/client` and add an `external_directory` ask rule

### OpenMausBot

1. Ask the owner for a pairing code from Settings > Phone, exchange it at `POST /api/auth/pair`, and set `OPENMAUSBOT_TOKEN` with an explicit `OMB_PORT`
2. Pass a `send_id` with every `send_bot_message` and `send_channel_message`, so a retry returns the first receipt
3. Use `wait_for_conversation` instead of polling, and on `needs-user` stop and tell the owner a card is waiting
4. Check a bot's access level with the owner before sending work. New bots run at Full access unless defaults were changed
5. Ask the owner to switch off Settings > General > Usage analytics if nothing beyond model calls should leave the machine
