Ahead on: - Maintenance & community, 55 against 15 Watch for: No API, MCP server or A2A endpoint for an outside agent. ### 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: - Reliability, 32 against 10 - Schema & documentation, 33 against 10 - Agent ergonomics, 57 against 0 - Security & auth, 34 against 0 - Payments & pricing, 60 against 30 - Transparency & trust, 60 against 52 Also in its favour: - No key needed to call it - Free to start without a card - Open source 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 ## Score by category | Category | Weight | Caddy | Leon | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 10 | 32 | Leon +22 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 10 | 33 | Leon +23 | | Agent ergonomics | 13% (16.2 this run) | 0 | 57 | Leon +57 | | Security & auth | 14% (17.5 this run) | 0 | 34 | Leon +34 | | Payments & pricing | 10% (12.5 this run) | 30 | 60 | Leon +30 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 55 | 15 | Caddy +40 | | Transparency & trust | 7% (8.8 this run) | 52 | 60 | Leon +8 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **16.7 · F** | **41 · E** | | ## Facts side by side | Fact | Caddy | Leon | | --- | --- | --- | | Kind | Platform | Agent harness | | Vendor | Caddy Technologies Inc. | Louis Grenard (Leon AI) | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | None | | Pricing | Free | Free | | x402 | no | no | | Licence | Closed service under Caddy's Terms of Service (Caddy Technologies Inc., last updated 27 April 2026). | MIT | | Read-only variant documented | yes | no | | llms.txt | yes | no | | Last release | 2026-10-13 | 2023-05-01 | | Terms last updated | | no document linked | | Privacy policy last updated | | no document linked | | Customer content may train models | | | | Terms restrict automated access | | | | Terms restrict benchmarking | | | | Terms or service can change without notice | | | | Arbitration or class-action waiver | | | | Popularity | none | 18k stars | ## Verdicts **Caddy.** Caddy is a free iMessage and RCS assistant in public beta that watches connected mail, calendars and work apps and asks before sending email or changing data. No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two. **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 ### Caddy 1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to. 2. Expect Caddy to ask the owner before it sends email or creates an invite. ### 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 ## Questions ### Which is better for AI agents, Caddy or Leon?

Caddy 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.
