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.

Town

Town is a hosted assistant that works across the owner's mail, calendar and work apps, and other systems can start its routines through per-routine webhooks with rotatable secrets, idempotency keys and documented errors. A caller can't read a run's result. The privacy policy and trust page disagree on whether training is on by default.

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

Town

  1. Start a Town routine with POST to its webhook URL, Authorization Bearer whsec_ secret, and application/json or text/plain. Expect 202 only.
  2. Send X-Town-Idempotency-Key with a stable event id on every retry so Town doesn't start a second run.
  3. Treat 404 as wrong secret, disabled endpoint or missing endpoint alike, and ask the owner to check Routine Settings rather than retrying.
  4. Send account_email only if the owner allowed the override. It must match a connected account in full and can't widen the routine's scope.
  5. Ask the owner to keep routines that act on webhook input in approval-required mode, as Town's own docs advise.

Other comparisons with Leon or Town

Disclosure

Town 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.

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.
