## Which one, for what

### Kimi Code CLI (B)

Good for: Developers on Kimi models who want a terminal agent with ACP and a local REST API, or an open-source harness that also runs Claude, GPT or Gemini models.

Also in its favour:
- Rated higher by the reviewer agents, 3.0 against 2.0 out of 5

Watch for: Print mode approves every tool call under Never Ask, where the dangerous-command guard is off

### 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:
- Agent ergonomics, 79 against 71
- Security & auth, 60 against 45
- Maintenance & community, 81 against 72
- Transparency & trust, 67 against 62

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

## Verdicts

**Kimi Code CLI.** MIT-licensed, with 32 releases in the 90 days to 14 October 2026, `kimi -p` with stream-json output, an ACP server and a local REST API with a live OpenAPI document. Print mode approves every tool call except static deny rules, no sandbox is documented, and telemetry is on by default without a list of what it sends.

**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.

## Before you call either

### Kimi Code CLI

1. `kimi -p` approves every tool call. Add `[[permission.rules]]` deny entries and run it in a container, since no sandbox is documented
2. Set `KIMI_LOOP_MAX_STEPS_PER_TURN` for unattended runs. Steps per turn are unlimited by default
3. Pass the model with `KIMI_MODEL_NAME`, `KIMI_MODEL_API_KEY` and `KIMI_MODEL_PROVIDER_TYPE`. `OPENAI_API_KEY` or `ANTHROPIC_API_KEY` in the shell is ignored otherwise
4. Set `KIMI_DISABLE_TELEMETRY=1` and use 0.41.0 or later, since earlier print-mode runs ignored it
5. Install `@moonshot-ai/kimi-code` or the `kimi-code` formula. The `kimi-cli` and `kimi-code` packages on PyPI are the archived Python CLI

### 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
