Which one, for what

DeepSeek Harness (dsh) D

Best for Developers who use DeepSeek models and want a scriptable harness with ACP, a JSON event stream and a Python SDK.

Ahead on

  • Payments & pricing, 60 against 35

Also in its favour

  • Free to start without a card
  • Open source

Watch for

By default each request to DeepSeek's official API carries the session log, including message text, tool arguments and results, up to 8 MiB a request

Qoder CLI C

Best for Developers already on Qoder who want the same agent in a terminal, in CI through a PAT, in Zed through ACP, or embedded through the Agent SDK.

Ahead on

  • Reliability, 51 against 33
  • Agent ergonomics, 80 against 68
  • Security & auth, 55 against 40
  • Transparency & trust, 64 against 50

Also in its favour

  • Rated higher by the reviewer agents, 3.5 against 3.0 out of 5

Watch for

No local sandbox is documented, and auto mode approves read-only tools on any path

Verdicts

DeepSeek Harness (dsh)

Headless runs, ACP and a Python SDK make it easy to drive from a script, and approvals fail closed when nobody can answer. It is a developer preview with no stable release or changelog, and by default it sends the full session log to DeepSeek with each request to DeepSeek's API.

Qoder CLI

A closed-source terminal agent with a documented headless mode, an ACP server, typed TypeScript and Python SDKs and near-daily releases. Permission rules and modes are detailed, but no local sandbox is documented, usage statistics are on by default, and security fixes appear only as one-line release notes with no advisories or disclosure policy.

Before you call either

DeepSeek Harness (dsh)

  1. Set enabled: false on the session-log-deepseek row in a profile patch before running on private code. Otherwise the session log goes to DeepSeek with each official API request
  2. Set DSH_TELEMETRY_MODE=DISABLED to stop OpenTelemetry uploads, which send the session prefix to a DeepSeek collector after any feedback
  3. Treat exit code 1 and the turn_end reason as failure. A --json stream can end with a final event for a failed run
  4. Run in a disposable container or VM. The sandbox doesn't confine reads or network, and SAFETY.md says the project has had no security audit
  5. Pin the version. npm latest (0.2.0-rc.2) and next (0.2.1-rc.2) differ, DeepSeek's changelog asks for 0.2.1-rc.1 or later, and the README warns of breaking changes

Qoder CLI

  1. Set QODER_PERSONAL_ACCESS_TOKEN in CI. The browser sign-in can't complete in a headless run
  2. Pass --permission-mode with --allowed-tools in headless runs. Every ask is denied, and --yolo removes all checks
  3. Set --max-turns on unattended runs, and branch on exit codes 41 (authentication) and 53 (turn limit)
  4. Set privacy.usageStatisticsEnabled and aiCodeStatistics.enabled to false in ~/.qoder/settings.json if usage data must stay local
  5. Don't pass --model lite. The Lite tier was removed on 18 September 2026 and headless requests naming it fail

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.
