## Which one, for what

### OpenAI Codex (BB)

Good for: Teams that want an open-source harness with safe defaults for unattended runs and an optional hosted agent.

Ahead on:
- Schema & documentation, 90 against 81
- Security & auth, 82 against 55
- Payments & pricing, 60 against 35
- Maintenance & community, 87 against 72
- Transparency & trust, 84 against 64

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card
- Open source

Watch for: Pre-1.0 at 0.163.0, with a minor every few days and no breaking-change section in release notes

### Qoder CLI (C)

Good 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.

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

**OpenAI Codex.** Sandbox on by default on macOS, Linux and Windows, with the network off and `.git` and `.codex` read-only. Pre-1.0 at 0.163.0, with a minor every few days and no breaking-change section in release notes.

**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

### OpenAI Codex

1. Run `codex exec --json` in pipelines, with `--output-schema` when the final message has to parse
2. Keep the default sandbox, which has the network off. `--yolo` removes both the sandbox and approvals
3. Replace `gpt-5.5` with `gpt-6.1-sol` in saved configs, custom agents and scripts under ChatGPT sign-in. GPT-5.5 retired there on 14 October 2026
4. Set `[analytics] enabled = false` and `[feedback] enabled = false` in config.toml to keep usage data local
5. Pin the npm version. A 0.x minor lands every few days

### 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
