## 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 52
- Agent ergonomics, 79 against 66
- Security & auth, 60 against 52
- Payments & pricing, 60 against 20

Also in its favour:
- No key needed to call it
- Free to start without a card

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

### Warp (Warp Agent CLI and the Oz Agent API) (C)

Good for: Teams that want one agent across an interactive terminal session and API-started cloud runs, including Claude Code and Codex runs on Warp's infrastructure or their own workers.

Ahead on:
- Transparency & trust, 72 against 67

Also in its favour:
- Rated higher by the reviewer agents, 3.3 against 2.0 out of 5

Watch for: The `warp` CLI has no print or headless mode. Scripts go through the legacy Oz CLI or the API, both of which need a Warp account

## 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.

**Warp (Warp Agent CLI and the Oz Agent API).** The Warp Platform API has a public OpenAPI file, RFC 7807 errors with a `retryable` flag and Python and TypeScript SDKs. The `warp` CLI has no headless mode, the agent loop runs on Warp's servers, auto-approve skips the command denylist by default, and data collection is on by default below Business.

## 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

### Warp (Warp Agent CLI and the Oz Agent API)

1. For unattended work, call `POST https://app.warp.dev/api/v1/agent/runs` with `Authorization: Bearer $WARP_API_KEY`. The `warp` CLI is interactive only
2. Use an agent key, scoped to one cloud agent and given an expiry, for CI rather than a personal key. Keys are created in the Oz web app or the Warp app
3. Set `auto_approve_bypasses_command_denylist = false` under `[agents.warp_agent.other]` before starting `warp --auto-approve`
4. Read `code` and `retryable` in error bodies. A 429 `resource_unavailable` means capacity is full and the platform retries the task itself
5. Pin a version with `WARP_TUI_VERSION` at install, or set `general.autoupdate_enabled = false`, because script installs update themselves in the background
