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.\n\n**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.\n\n## Before you call either\n\n### Leon\n\n1. 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\n2. 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\n3. Set `telemetry_enabled: false` and `runtime.pulse_enabled: false` in the profile `config.yml` for an unattended or private run\n4. 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\n5. Back up `LEON_CONNECTIONS_ENCRYPTION_KEY` from the profile `.env`. Without it the stored connections cannot be read\n\n### Zo Computer\n\n1. Send `POST https://api.zo.computer/zo/ask` with `Authorization: Bearer zo_sk_...` and an `input` string. The owner creates the token under Settings \u003e Advanced\n2. Pass `persona_id` for a persona with a narrow tool set. The token itself carries every permission the owner has\n3. 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\n4. Do not retry `/zo/ask` blindly after a timeout. No idempotency key is documented and the request may already have sent a message\n5. Append `.md` to any guide or reference URL for Markdown\n\n## Questions\n\n### Which is better for AI agents, Leon or Zo Computer?\n\nZo Computer scores 43.1 (E) on agent readiness against Leon's 41 (E), and leads in 3 of 7 scored categories. Leon leads on reliability, agent ergonomics and payments \u0026 pricing.\n\n### Can an agent call Leon and Zo Computer without installing anything?\n\nNo hosted endpoint is listed for Leon. Zo Computer has a hosted endpoint at https://api.zo.computer/mcp.\n\n### Are Leon and Zo Computer open source?\n\nLeon is open source (MIT). No open-source release is listed for Zo Computer.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/leon-vs-zo-computer.json, and with the fewest tokens: https://www.anchorterminal.com/compare/leon-vs-zo-computer.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"leon\", \"b\": \"zo-computer\"}`.
