Verdicts

nanobot

nanobot runs on the owner's machine under the MIT licence, with no telemetry found in its source and memory kept as files the owner can read and restore. No per-action approval step was found, and the shell sandbox and workspace restriction are off by default. Five security advisories were published between March and September 2026, all with fixes.

Orchid

Orchid is a paid executive assistant over iMessage, SMS and Telegram that holds drafts and calendar holds until the owner approves, with a public status page and a named subprocessor list. No outside agent can call it, there's no free tier, and its privacy policy allows training a personal model while its blog says it never trains.

Before you call either

nanobot

  1. Set tools.restrictToWorkspace to true and tools.exec.sandbox to bwrap or seatbelt before giving it real accounts. Both are off by default
  2. Run 0.3.0 or later. Earlier versions carry the published SSRF flaw in web fetch (GHSA-vc5v-6vwm-wf9m)
  3. Keep allowFrom narrow on every channel and never set ["*"] on Email, which has no pairing
  4. Write secrets as ${VAR} references in ~/.nanobot/config.json. Plain values are stored in clear text
  5. Use nanobot -m "..." for a one-shot run, and keep nanobot gateway running for channels, schedules and heartbeat

Orchid

  1. Don't plan to call Orchid from another agent. It answers only the owner's iMessage, SMS and Telegram threads.
  2. Check status.orchid.ai before telling the owner Orchid is down. The 7 August incident moved it to a new number.
  3. Tell the owner that drafts and holds wait for their approval unless they widen it.

Other comparisons with nanobot or Orchid

Disclosure

Orchid 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.
