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.\n\n**OpenCode.** Runs with no key or account on free OpenCode Zen models. Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox.\n\n## Before you call either\n\n### Agent Zero\n\n1. Set a UI login and password in Settings before publishing the port or opening a tunnel. The default has none\n2. Fill `allowed_users`, `allowed_numbers` or `sender_whitelist` before enabling a channel. An empty list accepts every sender\n3. Enable the Infection Check plugin when the agent reads mail, web pages or MCP results. It ships disabled\n4. Run v2.12 or later. It fixes a Telegram webhook authentication bypass and a WhatsApp media path traversal\n5. Call `POST /api_message` with the `X-API-KEY` header. The token changes when the UI login or password changes\n\n### OpenCode\n\n1. Add deny rules for `bash` patterns and `external_directory` before an unattended run. Most tools default to allow\n2. Set `\"autoupdate\": false` or `OPENCODE_DISABLE_AUTOUPDATE=1` and pin the version in CI\n3. Configure a provider key. With none, prompts go to free Zen models that may train on them\n4. Set `OPENCODE_SERVER_PASSWORD` before `opencode serve`. Without it the server runs unauthenticated\n5. Use `opencode run --format json` and read the event stream rather than the formatted output\n\n## Questions\n\n### Which is better for AI agents, Agent Zero or OpenCode?\n\nOpenCode scores 67.7 (B) on agent readiness against Agent Zero's 54.2 (C), and leads in 6 of 7 scored categories.\n\n### Are Agent Zero and OpenCode open source?\n\nYes. Agent Zero is open source (MIT). OpenCode is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agent-zero-vs-opencode.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agent-zero-vs-opencode.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agent-zero\", \"b\": \"opencode\"}`.
