The 2.0 Developer Preview has no tagged release, runs tools and a 30-minute proactive pulse with no approval step, listens on every network interface with client authentication off, and sends telemetry by default.\n\n**ZeroClaw.** Supervised autonomy is the default, so tools outside a short read-only list wait for the owner's approval, and secrets are encrypted in the config file. The docs state that command execution is not written to an audit log, and the project publishes no privacy policy or terms.\n\n## Before you call either\n\n### Leon\n\n1. Clone the develop branch for 2.0. `npm install --global @leon-ai/cli` and docs.getleon.ai install and describe the legacy 1.0 betas\n2. Set `client_interface.auth.enabled: true` and a `LEON_PROFILE_TOKEN` before the machine joins a shared network. The server binds 0.0.0.0\n3. Set `telemetry_enabled: false` and `runtime.pulse_enabled: false` in the profile `config.yml` for an unattended or private run\n4. Use `availability.tools.allowed` to limit tools. Shell, file writes, computer use and browser control are otherwise available to the agent with no approval prompt\n5. Back up `LEON_CONNECTIONS_ENCRYPTION_KEY` from the profile `.env`. Without it the stored connections cannot be read\n\n### ZeroClaw\n\n1. Keep `[risk_profiles.\u003calias\u003e] level = \"supervised\"`. `full` runs every tool not listed in `always_ask`, and the YOLO preset removes the sandbox and path rules too\n2. Add sending and account tools such as `send_via`, `google_workspace` and `http_request` to `always_ask` so a session-level Always grant cannot skip the prompt\n3. List senders in `[peer_groups.\u003cname\u003e] external_peers`. `[\"*\"]` accepts anyone on that channel\n4. Set `[web_fetch].allowed_domains` and `[http_request].allowed_domains`. Fetches run unprompted and the OS sandbox does not block egress\n5. Run one-shot tasks with `zeroclaw agent -a \u003calias\u003e -m \"\u003ctask\u003e\"`. A cron or webhook turn has no prompt, so shell calls fall to the command policy\n\n## Questions\n\n### Which is better for AI agents, Leon or ZeroClaw?\n\nZeroClaw scores 70.2 (BB) on agent readiness against Leon's 41 (E), and leads in 6 of 7 scored categories.\n\n### Are Leon and ZeroClaw open source?\n\nYes. Leon is open source (MIT). ZeroClaw is open source (MIT OR Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/leon-vs-zeroclaw.json, and with the fewest tokens: https://www.anchorterminal.com/compare/leon-vs-zeroclaw.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"leon\", \"b\": \"zeroclaw\"}`.
