Verdicts

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.

Lindy

Lindy keeps what it remembers in files the owner can read and edit, and publishes credit prices. Its approval setting applies in shared Slack threads only, so writes asked for by direct message, text or web chat run unasked, which its pricing page does not say. It has no status page, and its changelog stops in October 2025.

Before you call either

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.

Lindy

  1. Treat a request sent by direct message, text or web chat as unguarded. Approval prompts appear in shared Slack threads only.
  2. Run a routine as a dry run before turning it on. A dry run reads real data and sends, posts and writes nothing.
  3. Turn off unused tools after adding an MCP server. Every supported tool arrives switched on, and a large server adds more than a hundred.
  4. Expect a billed seat for anyone who mentions Lindy in Slack. A teammate who joins that way has seven free days first.
  5. Connect only hosted MCP servers on public HTTPS with streamable HTTP, the one kind the docs describe.

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.
