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.

Caddy

Caddy is a free iMessage and RCS assistant in public beta that watches connected mail, calendars and work apps and asks before sending email or changing data. No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two.

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

Caddy

  1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to.
  2. Expect Caddy to ask the owner before it sends email or creates an invite.

Disclosure

Caddy 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.
