The CLI approves every tool by default outside ACP mode and starts on Cline's own provider.\n\n**Pi.** Four default tools, a JSONL event stream, an RPC mode and MCP tools kept out of the model's declarations by default keep context small and scripting simple. Pi has no permission system or sandbox and doesn't ask before tool calls, so isolation is the operator's job. Version 1.0.0 is dated 1 October 2026.\n\n## Before you call either\n\n### Cline\n\n1. Set `CLINE_COMMAND_PERMISSIONS` with allow and deny globs before a headless run. The CLI approves every tool by default\n2. Pick a provider with `-P` and a key, or run `cline auth`. The default provider needs a Cline sign-in\n3. Untick 'Allow error and usage reporting', or turn off VS Code telemetry, before the first task\n4. Pin the CLI version. 2.3.0 was a malicious publish\n5. Keep the hub on 127.0.0.1 or set ROOM_SECRET, and run 3.0.30 or later\n\n### Pi\n\n1. Run Pi inside a container or VM for unattended work. It has no sandbox and doesn't ask before running shell commands\n2. Use `pi --mode json` and wait for `agent_settled`. A failed response doesn't set a nonzero exit code in JSON mode\n3. Split the JSONL stream on LF only. Node's `readline` also splits on U+2028 and U+2029, which are valid inside JSON strings\n4. Pass `--no-approve` or `--approve` in scripts to make the project trust decision explicit\n5. Set `PI_TELEMETRY=0` and `PI_SKIP_VERSION_CHECK=1`, or `PI_OFFLINE=1`, to stop the default requests to pi.dev\n\n## Questions\n\n### Which is better for AI agents, Cline or Pi?\n\nPi scores 68.4 (B) on agent readiness against Cline's 60.4 (C), and leads in 6 of 7 scored categories. Cline leads on reliability.\n\n### Are Cline and Pi open source?\n\nYes. Cline is open source (Apache-2.0). Pi is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cline-vs-earendil-pi.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cline-vs-earendil-pi.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cline\", \"b\": \"earendil-pi\"}`.
