Honcho is memory infrastructure for building stateful agents that understand changing people, agents, groups, projects, and ideas over time. Store messages and events, let Honcho reason in the background, then query peer representations, session context, search results, or natural-language insights from any model or framework. Use it managed at api.honcho.dev, run a local stack with the honcho CLI, or self-host the server yourself. Maintained by Plastic Labs; the same provider that shipped in-tree. Disclosure — conversation turns, derived conclusions and peer/session ids are sent to the Honcho API (api.honcho.dev by default, or the self-hosted base_url you configure) under your HONCHO_API_KEY; every request also carries X-Honcho-Host (Hermes version and OS platform) and X-Honcho-Plugin (plugin version) headers that Honcho records for usage attribution.
