Verdicts

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.

Tab

Tab is a private-beta texting assistant with a detailed security page on credential isolation and checkout binding, and a public updates page. No outside agent can call it, no price is published, and its privacy policy says nothing on training with user content.

Before you call either

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.

Tab

  1. Don't plan to call Tab from another agent. It answers only the owner's Messages or WhatsApp thread.
  2. Tell the owner that access needs a waitlist place and no price is published.

Other comparisons with Lindy or Tab

Disclosure

Tab 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.
