Which one, for what

Brea F

Best for An iPhone user who wants an assistant across many apps and websites with per-action approval.

Also in its favour

  • No incidents deducted, where Skydive loses 5 points for them

Watch for

No API, MCP server or A2A endpoint for an outside agent.

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

  • Reliability, 41 against 15
  • Schema & documentation, 81 against 10
  • Agent ergonomics, 59 against 0
  • Security & auth, 59 against 7
  • Payments & pricing, 35 against 20
  • Maintenance & community, 56 against 4
  • Transparency & trust, 75 against 46

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

Brea

Brea is an iMessage assistant with a free plan that needs no card, approval by reply before it sends, deletes or pays, and one-time Link cards for purchases. No outside agent can call it, paid prices sit inside the app, and no changelog or subprocessor list was found.

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

Brea

  1. Don't plan to call Brea from another agent. It answers only the owner's iMessage thread.
  2. Tell the owner that replying ALWAYS stops Brea asking again for that action.

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 Brea or Skydive

Disclosure

Brea 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.
