Also in its favour

  • Free to start without a card
  • No incidents deducted, where nanobot loses 6 points for them

Watch for

No API, MCP server or documented command an outside agent can call

nanobot B

Best for A technical owner who wants an assistant on their own machine across many chat apps, with file-based memory and a free choice of model.

Ahead on

  • Schema & documentation, 77 against 15
  • Agent ergonomics, 74 against 9
  • Security & auth, 63 against 49
  • Maintenance & community, 82 against 51

Watch for

Verdicts

Atticus

Atticus runs a person's Mac by voice on their existing Claude or Devin plan, with a sandboxed safe mode and a local log of every command. It has no API, MCP server or documented command for another agent, it is five days old, and it rebuilds itself from the main branch every six hours by default.

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

Atticus

  1. Don't plan to call Atticus from another agent. It takes requests only from its own shortcut and typing box
  2. If a user runs Atticus beside you, expect it to move windows and type into apps on the same Mac
  3. Point a user who wants pinned versions to Settings > About & Updates to turn off self-update

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
