Ahead on: - Reliability, 78 against 5 - Schema & documentation, 82 against 10 - Agent ergonomics, 70 against 0 - Security & auth, 74 against 0 - Payments & pricing, 60 against 20 - Maintenance & community, 78 against 2 - Transparency & trust, 65 against 23 Also in its favour: - No key needed to call it - Free to start without a card - Open source Watch for: The Claude provider runs with `permissionMode: 'bypassPermissions'`, so shell, file and web tools run inside the container with no prompt ### szn (F) Good for: A person who wants calls, emails and bookings done for them and has an access code. Also in its favour: - No incidents deducted, where NanoClaw loses 5 points for them Watch for: Early access by access code only. ## Score by category | Category | Weight | NanoClaw | szn | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 78 | 5 | NanoClaw +73 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 82 | 10 | NanoClaw +72 | | Agent ergonomics | 13% (16.2 this run) | 70 | 0 | NanoClaw +70 | | Security & auth | 14% (17.5 this run) | 74 | 0 | NanoClaw +74 | | Payments & pricing | 10% (12.5 this run) | 60 | 20 | NanoClaw +40 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 78 | 2 | NanoClaw +76 | | Transparency & trust | 7% (8.8 this run) | 65 | 23 | NanoClaw +42 | | Negative events | ≤15 | -5 | 0 | | | **Total** | | **68.3 · B** | **7.3 · F** | | ## Facts side by side | Fact | NanoClaw | szn | | --- | --- | --- | | Kind | Agent harness | Platform | | Vendor | NanoCo, Inc. | Nomadic Futures | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | None | OAuth or key | | Pricing | Free | Free | | x402 | no | no | | Licence | MIT | Closed service.

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. **szn.** szn is an errand assistant in early access that makes calls, sends emails and books for its owner, free during the preview for people with an access code. No outside agent can call it, no terms of service or legal entity appear in its policies, and its privacy policy says nothing on training. ## Before you call either ### NanoClaw 1. 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 2. Set `NANOCLAW_EGRESS_LOCKDOWN=true` before giving an agent credentials or an audience of strangers. The default leaves egress open 3. Put chats with different audiences in separate agent groups. Every session of a group shares one read-write workspace and memory tree 4. Turn on per-request approval for a secret in the gateway when its use should wait for a person. It is off unless configured 5. 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 ### szn 1. Don't plan to call szn from another agent. It answers only its web app, iMessage, SMS and email for the owner. 2. Tell the owner they need an access code to start, and that the acceptable use policy makes them responsible for confirming actions. ## Questions ### Which is better for AI agents, NanoClaw or szn?

szn competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
