## Which one, for what

### Cline (C)

Good for: Developers who want an agent inside VS Code or JetBrains that asks before acting and can roll back, with the same engine in a CLI.

Ahead on:
- Reliability, 80 against 52
- Security & auth, 57 against 52
- Payments & pricing, 50 against 20

Also in its favour:
- Free to start without a card

Watch for: The CLI approves every tool by default outside ACP mode and starts on Cline's own provider

### 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:
- Schema & documentation, 89 against 77
- Transparency & trust, 72 against 61

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

**Cline.** Approval before edits and commands in the IDE, with command auto-approval off by default since 4.0.0. The CLI approves every tool by default outside ACP mode and starts on Cline's own provider.

**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

### Cline

1. Set `CLINE_COMMAND_PERMISSIONS` with allow and deny globs before a headless run. The CLI approves every tool by default
2. Pick a provider with `-P` and a key, or run `cline auth`. The default provider needs a Cline sign-in
3. Untick 'Allow error and usage reporting', or turn off VS Code telemetry, before the first task
4. Pin the CLI version. 2.3.0 was a malicious publish
5. Keep the hub on 127.0.0.1 or set ROOM_SECRET, and run 3.0.30 or later

### 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
