## Which one, for what

### AstrBot (C)

Good for: Someone who wants one self-run bot answering on QQ, Telegram, Slack, Discord, Lark or WeCom, in private or group chats, with scheduled tasks, a knowledge base and plugins.

Ahead on:
- Reliability, 81 against 32
- Schema & documentation, 62 against 33
- Security & auth, 44 against 34
- Maintenance & community, 81 against 15

Watch for: No approval step before any tool call. The agent sends messages, creates scheduled tasks and calls MCP tools without asking

### 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:
- Transparency & trust, 60 against 40

Also in its favour:
- No key needed to call it

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

## Verdicts

**AstrBot.** Fourteen official messaging adapters, scheduled tasks and scoped API keys come in one AGPL-3.0 program with releases most weeks. No tool call asks for approval, no mail, calendar or long-term memory connector is built in, and usage statistics, including the machine's hostname, are sent by default.

**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.

## Before you call either

### AstrBot

1. Set `ASTRBOT_DISABLE_METRICS=1` before the first start. Statistics, including the hostname, are sent to tickstats.soulter.top by default
2. Set `dashboard.host` to 127.0.0.1 in `data/cmd_config.json`, or the `DASHBOARD_HOST` variable, unless remote access is intended. The default is 0.0.0.0
3. Create an `abk_` key in Settings, OpenAPI with only the scopes needed, and send it as `Authorization: Bearer` or `X-API-Key`
4. Include `username` in every `POST /api/v1/chat` body. Without the `chat:admin` scope an administrator ID is rejected
5. Check Extensions, Future Tasks after asking for a schedule. One-off tasks are deleted after their run even when the run fails

### 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
