Verdicts

AstrBot

Fourteen official messaging adapters, scheduled tasks and scoped API keys come in one AGPL-3.0 program with releases most weeks. No tool call asks for approval, no mail, calendar or long-term memory connector is built in, and usage statistics, including the machine's hostname, are sent by default.

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.

Before you call either

AstrBot

  1. Set ASTRBOT_DISABLE_METRICS=1 before the first start. Statistics, including the hostname, are sent to tickstats.soulter.top by default
  2. Set dashboard.host to 127.0.0.1 in data/cmd_config.json, or the DASHBOARD_HOST variable, unless remote access is intended. The default is 0.0.0.0
  3. Create an abk_ key in Settings, OpenAPI with only the scopes needed, and send it as Authorization: Bearer or X-API-Key
  4. Include username in every POST /api/v1/chat body. Without the chat:admin scope an administrator ID is rejected
  5. Check Extensions, Future Tasks after asking for a schedule. One-off tasks are deleted after their run even when the run fails

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.

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.
