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.

Talorys

Talorys is an MIT-licensed assistant its owner deploys to their own Cloudflare account, with no telemetry, a documented threat model and code-enforced confirmation for destructive tools. It is two days old at version 0.1.5, has no mail, calendar or payment connections, and no interface for an outside agent.

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

Talorys

  1. Run npx create-talorys@latest with Node.js 22 or later and a Cloudflare login or an API token with Workers, Pages and Workers AI permissions.
  2. Don't script the /api routes. They need the owner's session cookie and CSRF header and aren't documented for other callers.
  3. Update with npx create-talorys@latest update. Only the latest version gets security fixes.

Other comparisons with Leon or Talorys

Disclosure

Talorys competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.

Machine-readable

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
