## Which one, for what

### Leon (E)

Good for: A developer who wants a self-hosted assistant with memory, computer use and a local model, and who will read the source.

Ahead on:
- Reliability, 32 against 15
- Agent ergonomics, 57 against 34
- Payments & pricing, 60 against 40

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

Watch for: No tagged release of the core since 1.0.0-beta.8 on 1 May 2023. The 2.0 Developer Preview is installed by cloning the develop branch

### 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 33
- Maintenance & community, 68 against 15

Also in its favour:
- A hosted endpoint, with nothing to install

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

**Leon.** Connected-app credentials are encrypted per profile and the Gmail connection is read-only. The 2.0 Developer Preview has no tagged release, runs tools and a 30-minute proactive pulse with no approval step, listens on every network interface with client authentication off, and sends telemetry by default.

**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

### Leon

1. Clone the develop branch for 2.0. `npm install --global @leon-ai/cli` and docs.getleon.ai install and describe the legacy 1.0 betas
2. Set `client_interface.auth.enabled: true` and a `LEON_PROFILE_TOKEN` before the machine joins a shared network. The server binds 0.0.0.0
3. Set `telemetry_enabled: false` and `runtime.pulse_enabled: false` in the profile `config.yml` for an unattended or private run
4. Use `availability.tools.allowed` to limit tools. Shell, file writes, computer use and browser control are otherwise available to the agent with no approval prompt
5. Back up `LEON_CONNECTIONS_ENCRYPTION_KEY` from the profile `.env`. Without it the stored connections cannot be read

### 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
