Which one, for what

GitHub Copilot CLI C

Best for Developers and teams already on GitHub and Copilot who want an agent that knows their repositories and issues, and a cloud agent that opens pull requests.

Ahead on

  • Agent ergonomics, 72 against 66
  • Security & auth, 63 against 52
  • Payments & pricing, 40 against 20

Also in its favour

  • Free to start without a card

Watch for

Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026

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 72
  • Maintenance & community, 84 against 77

Also in its favour

  • Open source
  • 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

GitHub Copilot CLI

Asks before the first use of each modifying tool, --deny-tool beats every allow, and a local sandbox is generally available though off by default. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.

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

GitHub Copilot CLI

  1. Pass --deny-tool for anything destructive. It wins over --allow-all-tools and --allow-tool
  2. Turn on the sandbox with /sandbox enable or --sandbox. It's off by default
  3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026
  4. Move off Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra before 16 November 2026
  5. Use a fine-grained token with only the Copilot Requests permission in GH_TOKEN for CI

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.
