The 2.0 Developer Preview is installed by cloning the develop branch\n\n### NanoClaw (B)\n\nGood for: A technical owner who wants an assistant on their own machine, reachable from chat apps, with container isolation and scheduled tasks, and who is willing to keep a fork.\n\nAhead on:\n- Reliability, 78 against 32\n- Schema \u0026 documentation, 82 against 33\n- Agent ergonomics, 70 against 57\n- Security \u0026 auth, 74 against 34\n- Maintenance \u0026 community, 78 against 15\n- Transparency \u0026 trust, 65 against 60\n\nWatch for: The Claude provider runs with `permissionMode: 'bypassPermissions'`, so shell, file and web tools run inside the container with no prompt\n\n\n## Score by category\n\n| Category | Weight | Leon | NanoClaw | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 32 | 78 | NanoClaw +46 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 33 | 82 | NanoClaw +49 |\n| Agent ergonomics | 13% (16.2 this run) | 57 | 70 | NanoClaw +13 |\n| Security \u0026 auth | 14% (17.5 this run) | 34 | 74 | NanoClaw +40 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 60 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 15 | 78 | NanoClaw +63 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 60 | 65 | NanoClaw +5 |\n| Negative events | ≤15 | 0 | -5 | |\n| **Total** | | **41 · E** | **68.3 · B** | |\n\n## Facts side by side\n\n| Fact | Leon | NanoClaw |\n| --- | --- | --- |\n| Kind | Agent harness | Agent harness |\n| Vendor | Louis Grenard (Leon AI) | NanoCo, Inc. |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | None | None |\n| Pricing | Free | Free |\n| x402 | no | no |\n| Licence | MIT | MIT |\n| Read-only variant documented | no | no |\n| llms.txt | no | yes |\n| Last release | 2023-05-01 | 2026-10-09 |\n| Terms last updated | no document linked | no document linked |\n| Privacy policy last updated | no document linked | no document linked |\n| Customer content may train models | | |\n| Terms restrict automated access | | |\n| Terms restrict benchmarking | | |\n| Terms or service can change without notice | | |\n| Arbitration or class-action waiver | | |\n| Popularity | 18k stars | 31k stars |\n\n## Verdicts\n\n**Leon.** Connected-app credentials are encrypted per profile and the Gmail connection is read-only. 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**NanoClaw.** Each session runs in an unprivileged Docker container and API keys stay in a credential gateway on the host, so a manipulated agent cannot read them. Inside the container the agent runs with permission prompts off, network egress is open by default, and it can message any chat it is wired to without approval.\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### NanoClaw\n\n1. Install with `git clone` and `bash nanoclaw.sh`. There is no registry package, and setup needs Docker, Node 22 or later and a Claude or Codex credential\n2. Set `NANOCLAW_EGRESS_LOCKDOWN=true` before giving an agent credentials or an audience of strangers. The default leaves egress open\n3. Put chats with different audiences in separate agent groups. Every session of a group shares one read-write workspace and memory tree\n4. Turn on per-request approval for a secret in the gateway when its use should wait for a person. It is off unless configured\n5. On OneCLI installs, move the gateway to 1.42.0 by the upgrade guide before updating to 2026.10.0. The updater stops until that is done\n\n## Questions\n\n### Which is better for AI agents, Leon or NanoClaw?\n\nNanoClaw scores 68.3 (B) on agent readiness against Leon's 41 (E), and leads in 6 of 7 scored categories.\n\n### Are Leon and NanoClaw open source?\n\nYes. Leon is open source (MIT). NanoClaw is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/leon-vs-nanoclaw.json, and with the fewest tokens: https://www.anchorterminal.com/compare/leon-vs-nanoclaw.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"leon\", \"b\": \"nanoclaw\"}`.
