Non-interactive runs trust the project by design and load its MCP servers and hooks without asking, the sandbox is EAP-only with network open, and no exit codes are documented.\n\n**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.\n\n## Before you call either\n\n### Junie CLI\n\n1. Run headless only in repositories you trust. One-shot and piped runs load the project's MCP servers, hooks and skills without asking\n2. Set `JUNIE_API_KEY` (from junie.jetbrains.com/cli) or a provider key such as `JUNIE_ANTHROPIC_API_KEY` in CI. The default sign-in opens a browser\n3. Add `--output-format json` or `--json-output-file` to parse results. Check the output, since exit codes aren't documented\n4. Pass `--share-anonymous-statistics false` if no usage statistics may leave the runner\n5. Pin a build with `--use-version` and `--skip-update-check`. The CLI updates itself on start by default\n\n### OpenAI Codex\n\n1. Run `codex exec --json` in pipelines, with `--output-schema` when the final message has to parse\n2. Keep the default sandbox, which has the network off. `--yolo` removes both the sandbox and approvals\n3. 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\n4. Set `[analytics] enabled = false` and `[feedback] enabled = false` in config.toml to keep usage data local\n5. Pin the npm version. A 0.x minor lands every few days\n\n## Questions\n\n### Which is better for AI agents, Junie CLI or OpenAI Codex?\n\nOpenAI Codex scores 73.4 (BB) on agent readiness against Junie CLI's 53.2 (D), and leads in every scored category.\n\n### Are Junie CLI and OpenAI Codex open source?\n\nNo open-source release is listed for Junie CLI. OpenAI Codex is open source (Apache-2.0 (Codex CLI, its Rust crates and the TypeScript and Python SDKs). Codex cloud is a hosted service under OpenAI's terms).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/junie-vs-openai-codex.json, and with the fewest tokens: https://www.anchorterminal.com/compare/junie-vs-openai-codex.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"junie\", \"b\": \"openai-codex\"}`.
