## Which one, for what

### Agent Zero (C)

Good for: A technical owner who wants an agent with its own Linux machine, reachable from Telegram, WhatsApp or email, with scheduled tasks and editable memory.

Ahead on:
- Reliability, 57 against 52
- Payments & pricing, 60 against 20

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

Watch for: No approval step before shell commands, file changes or outgoing messages. Tool Access defaults to allow

### 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 64
- Maintenance & community, 84 against 75
- Transparency & trust, 72 against 55

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

**Agent Zero.** Self-hosted under the MIT licence, with nine releases in the 90 days to 12 October 2026 and breaking changes listed in the release notes. The agent runs shell commands in its container with no approval step, the web interface has no login by default, and five CVEs from the past year have no published GitHub advisory.

**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

### Agent Zero

1. Set a UI login and password in Settings before publishing the port or opening a tunnel. The default has none
2. Fill `allowed_users`, `allowed_numbers` or `sender_whitelist` before enabling a channel. An empty list accepts every sender
3. Enable the Infection Check plugin when the agent reads mail, web pages or MCP results. It ships disabled
4. Run v2.12 or later. It fixes a Telegram webhook authentication bypass and a WhatsApp media path traversal
5. Call `POST /api_message` with the `X-API-KEY` header. The token changes when the UI login or password changes

### 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
