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**OpenHands.** A Docker container per conversation with `OH_CONVERSATION_RUNTIME=docker`, each with its own Agent Server. Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem.\n\n## Before you call either\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### OpenHands\n\n1. Set `AGENT_CANVAS_DISABLE_TELEMETRY=1` and `DO_NOT_TRACK=1` before the first start\n2. Start Canvas with `OH_CONVERSATION_RUNTIME=docker` or use the Docker image. The npm install runs the agent on the host\n3. Turn on confirmation mode with a risk threshold. Canvas starts with it off\n4. Use the SDK or the Agent Server API for headless runs. The `openhands --headless` CLI is no longer maintained\n5. Set `filter_tools_regex` on the agent to keep unneeded MCP tool definitions out of the context\n\n## Questions\n\n### Which is better for AI agents, Pi or OpenHands?\n\nOpenHands scores 70.8 (BB) on agent readiness against Pi's 68.4 (B), and leads in 5 of 7 scored categories.\n\n### Are Pi and OpenHands open source?\n\nYes. Pi is open source (MIT). OpenHands is open source (MIT (Agent Canvas, SDK, tools and Agent Server). OpenHands Cloud is a hosted service).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/earendil-pi-vs-openhands.json, and with the fewest tokens: https://www.anchorterminal.com/compare/earendil-pi-vs-openhands.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"earendil-pi\", \"b\": \"openhands\"}`.
