## Which one, for what

### CowAgent (C)

Good 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 15
- Agent ergonomics, 59 against 34
- Security & auth, 43 against 37
- Payments & pricing, 60 against 40
- Maintenance & community, 83 against 68

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

### Zo Computer (E)

Good for: One person who wants a hosted assistant with its own Linux machine, reachable by text message and chat apps, and who accepts that the assistant acts on connected accounts without a documented approval step.

Ahead on:
- Schema & documentation, 73 against 67
- Transparency & trust, 60 against 45

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where CowAgent loses 5 points for them

Watch for: The access token for the API and MCP endpoint grants full access to the workspace, with no scoped or read-only token documented

## 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.

**Zo Computer.** Zo publishes an OpenAPI file, Markdown docs, plan prices and a named list of the providers that receive user content. One access token grants full access to the workspace, no approval step before sending or buying was found in the reviewed docs, and no status page, rate limit or SLA is published.

## 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

### Zo Computer

1. Send `POST https://api.zo.computer/zo/ask` with `Authorization: Bearer zo_sk_...` and an `input` string. The owner creates the token under Settings > Advanced
2. Pass `persona_id` for a persona with a narrow tool set. The token itself carries every permission the owner has
3. Set `memory_mode` to `off` to keep workspace memory out of a request. The field is in the OpenAPI file and absent from the API guide
4. Do not retry `/zo/ask` blindly after a timeout. No idempotency key is documented and the request may already have sent a message
5. Append `.md` to any guide or reference URL for Markdown
