Verdicts

OpenClaw

Self-hosted under the MIT licence, with state, memory and credentials kept on the owner's machine and no paid tier. A fresh install runs tools on the host with full access, no approval prompt and no sandbox, and the project has published 722 security advisories since January 2026, 14 of them critical.

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

OpenClaw

  1. Set a session permission mode of guarded or workspace, or tools.exec.mode, before connecting mail. The default runs host commands without approval
  2. Turn on agents.defaults.sandbox for any agent that reads mail, web pages or attachments. Sandboxing is off by default
  3. Set tools.message.crossContext.allowAcrossProviders and allowWithinProvider to false to confine sends to the current conversation
  4. Route incoming mail to a restricted reader agent, as the IMAP and Gmail guides show, and deny gateway, cron, sessions_spawn and sessions_send for it
  5. Run openclaw security audit after setup, and treat the Gateway token as an owner credential. POST /tools/invoke accepts it with full operator access

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.

Disclosure

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.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
