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
