open-duet vs agmsg

open-duet: Open Duet is an open-source workspace for named AI agents that runs on your computer or a server you control. Each agent has instructions, an engine, a workspace, memory and approval settings; a lead agent can delegate to specialists, routines run on schedules or triggers, and you review tool activity and approvals in the app. It brings no model of its own: you connect Claude Code, Codex, Gemini CLI, Cursor, any ACP agent, OpenRouter or an OpenAI-compatible API.; agmsg: agmsg lets CLI coding agents such as Claude Code, Codex, Gemini CLI, GitHub Copilot CLI, Antigravity and OpenCode message each other through a shared local SQLite file. It needs only bash and sqlite3, with no daemon, broker or MCP server, and message history stays in the database for replay.
