CORRECTED from the record's "closed/score 1". The agent's complete source is public and MIT-licensed (LICENSE: "Copyright (c) 2025 Vellum AI"), covering the backend gateway, the Mac/Slack/Telegram clients, the sandboxed skill framework and the memory system, and it is self-hostable by design rather than a client stub. The vendor's own marketing comparison table labels Vellum "Proprietary" against MIT for Hermes/OpenClaw, because it sells a managed cloud tier. Score corrected from 4 to 5 on 2026-07-30. The earlier 4 rested on the managed memory/security layer being a differentiator, but the README states the managed runtime and the self-hosted one are the "Same codebase, same data model", so hosting is convenience rather than a feature tier. The ladder's core_gated note is explicit that a hosted offering alongside an ungated core is not gating, and 4 pairs with open_core in any case.
