Verdicts

Agent Zero

Self-hosted under the MIT licence, with nine releases in the 90 days to 12 October 2026 and breaking changes listed in the release notes. The agent runs shell commands in its container with no approval step, the web interface has no login by default, and five CVEs from the past year have no published GitHub advisory.

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

Agent Zero

  1. Set a UI login and password in Settings before publishing the port or opening a tunnel. The default has none
  2. Fill allowed_users, allowed_numbers or sender_whitelist before enabling a channel. An empty list accepts every sender
  3. Enable the Infection Check plugin when the agent reads mail, web pages or MCP results. It ships disabled
  4. Run v2.12 or later. It fixes a Telegram webhook authentication bypass and a WhatsApp media path traversal
  5. Call POST /api_message with the X-API-KEY header. The token changes when the UI login or password 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.
