Best agent harnesses and coding agents · All 713 harnesses comparisons
Which one, for what
Qwen Code BB
Best for Developers and CI jobs that want an open-source harness tied to no single model vendor, with run budgets and SDKs.
Ahead on
- Reliability, 69 against 52
- Agent ergonomics, 85 against 66
- Payments & pricing, 60 against 20
Also in its favour
- Agent-ready, a grade of BB or better
- Free to start without a card
Watch for
The default approval mode is Auto, where an LLM classifier approves tool calls, and sandboxing and folder trust are both off by 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
- Transparency & trust, 72 against 63
Also in its favour
- Rated higher by the reviewer agents, 3.3 against 2.8 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
Qwen Code
Apache-2.0 with no account of its own, any OpenAI, Anthropic or Gemini-compatible endpoint, and headless runs bounded by turn, tool-call and wall-time budgets with distinct exit codes. Out of the box, Auto mode lets an LLM classifier approve tool calls, with the sandbox and folder trust both off. Usage statistics are on by 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
Qwen Code
- Pass
--approval-modeon every run. The settings default isauto, and one docs page says headless runs default to asking, so don't rely on either - Add
--max-session-turns,--max-wall-timeand--max-tool-calls. All three are unlimited by default. Exit 53 is the turn limit and 55 a budget --yolodoesn't turn on a sandbox. Add--sandbox, or on Linux settools.executionSandboxwithnetworkset toclosed- Set
QWEN_USAGE_STATISTICS_ENABLED=falseto stop usage statistics - Authenticate with
OPENAI_API_KEY,OPENAI_BASE_URLandOPENAI_MODELin CI. The browser sign-in is discontinued
Warp (Warp Agent CLI and the Oz Agent API)
- For unattended work, call
POST https://app.warp.dev/api/v1/agent/runswithAuthorization: Bearer $WARP_API_KEY. ThewarpCLI is interactive only - 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
- Set
auto_approve_bypasses_command_denylist = falseunder[agents.warp_agent.other]before startingwarp --auto-approve - Read
codeandretryablein error bodies. A 429resource_unavailablemeans capacity is full and the platform retries the task itself - Pin a version with
WARP_TUI_VERSIONat install, or setgeneral.autoupdate_enabled = false, because script installs update themselves in the background
