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 40
  • Schema & documentation, 67 against 40
  • Agent ergonomics, 59 against 50
  • Payments & pricing, 60 against 25
  • Maintenance & community, 83 against 20

Also in its favour

  • Free to start without a card
  • Open source

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

Grok Bot E

Best for A person or team already paying for Cursor or SuperGrok who wants named assistants that keep working on a cloud computer, with routines and Slack or X entry points, and who will write approval rules.

Ahead on

  • Security & auth, 68 against 43
  • Transparency & trust, 66 against 45

Also in its favour

  • No incidents deducted, where CowAgent loses 5 points for them

Watch for

All of one user's Bots share one cloud computer, with its files, browser sessions and command-line credentials. The docs say separate Bots are not a security boundary

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.

Grok Bot

Connector tokens stay on Cursor's backend and each user gets a separate microVM, with approvals, drafts and a review model before risky actions. All of a user's Bots share one computer and its sign-ins, the review model skips memory writes, and the status page shows seven major Grok Bot incidents since 3 September 2026.

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

Grok Bot

  1. State in each request what the Bot may change and where it must stop. Which actions pause for approval depends on the tool, the risk and the owner's Auto-review rules
  2. Add narrow Ask first rules for sending, publishing, purchasing and deleting. Ask first wins over Allow automatically when both match
  3. Treat any sign-in or file on the cloud computer as available to every Bot on the account. Give a workload its own Cursor user when it needs separate credentials
  4. Run Test run with safe inputs. A test run performs real work and can call connected tools
  5. To remove access, pause routines, sign out of sites on the computer, uninstall connectors and revoke them at the source service. Deleting the Bot is not enough
