The status page records three critical and several major incidents on the cloud agent between 22 July and 24 September 2026, and no rate limit figures or retry guidance were found in the reviewed documentation.\n\n**Gemini CLI.** Apache-2.0, CI passing on main, and 583 open issues with priority labels. Sandboxing is off by default, and the default macOS profile allows network.\n\n## Before you call either\n\n### Devin\n\n1. Use a `cog_` service-user key with the Member role. Legacy `apk_` keys fail against v3 and the MCP server with 401 or 403\n2. Set `max_acu_limit` on every session you create. Usage is metered by the work done and has no published unit rate\n3. Session creation is not idempotent in v3. After a timeout, list sessions by tag before creating again\n4. Enterprise keys and personal access tokens must send `X-Org-Id` to the MCP server. Organisation-scoped keys resolve it automatically\n5. Create scheduled work as an automation. POST to the schedules endpoint returns 403 for migrated organisations since 24 September 2026\n\n### Gemini CLI\n\n1. Set `GEMINI_TRUST_WORKSPACE` to true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own\n2. Turn on the sandbox with `-s` or `tools.sandbox`, and pick a proxied Seatbelt profile on macOS to cut network\n3. Set `privacy.usageStatisticsEnabled` to false to stop usage statistics\n4. Read the exit code. 42 is bad input and 53 is the turn limit\n5. Use `--output-format stream-json` to get tool calls and results as JSONL events\n\n## Questions\n\n### Which is better for AI agents, Devin or Gemini CLI?\n\nGemini CLI scores 72 (BB) on agent readiness against Devin's 55.7 (C), and leads in 6 of 7 scored categories. Devin leads on security \u0026 auth.\n\n### Are Devin and Gemini CLI open source?\n\nNo open-source release is listed for Devin. Gemini CLI is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/devin-vs-gemini-cli.json, and with the fewest tokens: https://www.anchorterminal.com/compare/devin-vs-gemini-cli.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"devin\", \"b\": \"gemini-cli\"}`.
