Verdicts

folk

folk is a texting accountability assistant with its own cloud computer, a free tier with no card and a privacy policy that rules out training on user data. No outside agent can call it, no status page or changelog was found, and its llms.txt and pricing file disagree on free limits and Max's price.

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.

Before you call either

folk

  1. Don't plan to call folk from another agent. It answers only the owner's iMessage, Telegram or WhatsApp thread and iPhone app.
  2. Quote limits and prices from pricing.md and the terms, and note that llms.txt gives different free-tier limits.

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

Other comparisons with folk or nanobot

Disclosure

folk 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.
