Which one, for what

CowAgent C

Best for One technical owner who wants an assistant on WeChat, Feishu, DingTalk, Telegram, Slack or Discord with memory in local files and a choice of Chinese and Western model providers.

Ahead on

  • Reliability, 84 against 67
  • Maintenance & community, 83 against 74

Also in its favour

  • Free to start without a card

Watch for

Source and Docker installs default to full-access, and no mode asks the owner before a shell command, a file send or an MCP call

IronClaw B

Best for One technical owner who wants a self-hosted assistant over Gmail, Calendar, Slack and Telegram with credentials kept out of the model's reach.

Ahead on

  • Schema & documentation, 74 against 67
  • Agent ergonomics, 69 against 59
  • Security & auth, 66 against 43
  • Transparency & trust, 75 against 45

Watch for

Global auto-approve defaults to on in the 1.4.1 source, so tools marked ask (send, trash, delete) run without a prompt. Only financial, approval and budget effects always ask

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.

IronClaw

Credentials stay in an encrypted store and are injected at the host boundary, and extensions declare per-tool permissions, network targets and OAuth scopes. The global auto-approve setting defaults to on in the 1.4.1 source, so tools marked ask, such as gmail.send_message, run unprompted until the owner turns it off.

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

IronClaw

  1. Open Settings and turn off global auto-approve, or set send and delete tools to ask each time, before connecting mail or chat accounts
  2. Install with the release installer and run ironclaw onboard. 1.x does not migrate 0.29 data, so use a fresh home directory
  3. Call POST /api/v1/responses with the bearer token from ~/.ironclaw/reborn/webui-token. Keep under 30 requests in 60 seconds
  4. Resolve approval and OAuth gates in the web interface. The Responses API fails the turn instead of surfacing them
  5. Connect MCP servers over HTTP only. The stdio transport is rejected
