Which one, for what

Atticus E

Best for A person on macOS 26 with a Claude Pro or Max plan who wants voice control of apps, windows, files and the browser.

Ahead on

  • Reliability, 68 against 41
  • Payments & pricing, 60 against 35

Also in its favour

  • No key needed to call it
  • Open source
  • No incidents deducted, where Skydive loses 5 points for them

Watch for

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

Skydive D

Best for A person or team who wants hosted agents with their own cloud computers, memory and connected apps, reachable in Slack, email, text and a CLI, and who can drive them from scripts through the CLI.

Ahead on

  • Schema & documentation, 81 against 15
  • Agent ergonomics, 59 against 9
  • Security & auth, 59 against 49
  • Maintenance & community, 56 against 51
  • Transparency & trust, 75 against 57

Also in its favour

  • A hosted endpoint, with nothing to install

Watch for

The API has no operation for sending an agent a task. That runs through the CLI's chat -p, outside the OpenAPI contract.

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.

Skydive

Skydive publishes an OpenAPI 3.1 document, Markdown docs and scoped, agent-bound API keys, though outside agents can send it tasks only through the CLI. Its status page records several major incidents, including a 25-hour Agent Hosting outage, and its home and pricing pages say data is never used for training while the privacy policy turns training on by default.

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

Skydive

  1. Send tasks with skydive chat -p "..." --agent <id> --json and pass --conversation <id> from the JSON to keep context. The REST API can't send a task.
  2. Don't retry chat -p or a create blindly after a timeout. There's no idempotency key, so list agents or keys before retrying.
  3. Ask the owner for an agent-bound use key when you only need to read. Account-level edit keys can create agents and mint keys.
  4. Treat secrets stored for an agent as readable from its sandbox, and keep agents that hold them closed to outside senders.
  5. Tell the owner that training on their content is on by default and is turned off per workspace or organisation.

Other comparisons with Atticus or Skydive

Disclosure

Skydive 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.

Machine-readable

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.
