Verdicts

CowAgent

MIT software with seven releases in 90 days, memory kept as plain files in the owner's workspace and three per-session permission modes. Source and Docker installs default to full-access, no action asks for approval, and an open report of 31 July 2026 says group members could reach the owner's files through the bot.

Del

Del is a hosted texting assistant and task workspace across iMessage, WhatsApp, Telegram, SMS, Discord and Slack, with a near-daily public changelog and a card-free 14-day trial. No outside agent can call it, no status page or security contact was found, and recent updates let some email actions skip approval.

Before you call either

CowAgent

  1. Set agent_permission_mode to workspace-write or read-only before connecting any channel. Source and Docker installs default to full-access
  2. Keep the bot out of group chats that include other people. Any member who mentions it reaches the same tools as the owner
  3. Set web_password before changing web_host to 0.0.0.0. The password is empty by default
  4. Set external_api_token to enable POST /v1/chat/completions, and send conversation_id to keep one session. The model field does not select a model
  5. Run it in a container for a hard boundary. The docs and the source both say the permission modes are not isolation

Del

  1. Don't plan to call Del from another agent. It answers only the owner's messaging threads and web workspace.
  2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro.

Disclosure

Del 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.
