Which one, for what

OpenHands BB

Best for Teams that want to self-host a coding agent with a web UI, per-conversation Docker sandboxes and scheduled or webhook automations, or embed the agent through a Python SDK and REST API.

Ahead on

  • Reliability, 83 against 52
  • Agent ergonomics, 78 against 66
  • Security & auth, 66 against 52
  • Payments & pricing, 60 against 20

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem

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

  • Transparency & trust, 72 against 67

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

OpenHands

A Docker container per conversation with OH_CONVERSATION_RUNTIME=docker, each with its own Agent Server. Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem.

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

OpenHands

  1. Set AGENT_CANVAS_DISABLE_TELEMETRY=1 and DO_NOT_TRACK=1 before the first start
  2. Start Canvas with OH_CONVERSATION_RUNTIME=docker or use the Docker image. The npm install runs the agent on the host
  3. Turn on confirmation mode with a risk threshold. Canvas starts with it off
  4. Use the SDK or the Agent Server API for headless runs. The openhands --headless CLI is no longer maintained
  5. Set filter_tools_regex on the agent to keep unneeded MCP tool definitions out of the context

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.
