Which one, for what

goose BB

Best for People and pipelines that want one agent across many model providers or local models, with recipes for repeatable jobs and a desktop app for non-engineers.

Ahead on

  • Reliability, 77 against 52
  • Agent ergonomics, 82 against 66
  • Security & auth, 77 against 52
  • Payments & pricing, 60 against 20

Also in its favour

  • Agent-ready, a grade of BB or better
  • No key needed to call it
  • Free to start without a card

Watch for

Autonomous mode, which approves every tool call, is the default

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

Best 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 81
  • Transparency & trust, 72 against 63

Also in its favour

  • Rated higher by the reviewer agents, 3.3 against 2.5 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

goose

Telemetry off until the user opts in, with the collected fields listed. Autonomous mode, which approves every tool call, is the default.

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

goose

  1. Set GOOSE_MODE=smart_approve or approve before a run. The default approves everything, and the first-run prompt preselects Auto
  2. Pass --max-turns with a real limit. The default is 1000
  3. Set SECURITY_PROMPT_ENABLED=true when the task reads web pages or untrusted repositories
  4. Use --output-format json and --no-session in CI, and check the exit code
  5. Point remotes and links at aaif-goose/goose and goose-docs.ai. The block/goose paths redirect

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

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
