littleguys

littleguys is a small, free, open-source Mac and Windows app for talking to your AI agents, WhatsApp-style. Each agent is a contact with its own chats: OpenClaw agents, Hermes Agent profiles, Claude Code, and Codex, Gemini CLI, Goose, OpenCode or any other Agent Client Protocol (ACP) agent, on this computer or on other machines. A little guy in the menu bar (the taskbar on Windows) shows who's working, who replied and who needs you.

Chats have streaming replies, tool-call chips and attachments. When a command needs your OK, it shows up as a card: allow once, always allow, or deny. Clicking the guy in the menu bar lists every agent with a live status, the last message and a quick reply. Routines run on friendly schedules and post their results in a thread.

It connects to several OpenClaw gateways at once and finds them on your tailnet and LAN. It follows every Claude Code session on the computer, in a terminal or in the background. ACP agents are added in one click from the ACP registry. If OpenClaw isn't installed yet, littleguys can install and set it up for you.

There's no account, no cloud service and no telemetry: it talks straight to your agents. On a Mac it needs macOS 13 or later and runs on Apple silicon and Intel; on Windows it needs Windows 10 or 11 (x64). It updates itself. Install it with Homebrew (brew install herval/tap/littleguys), or the .dmg or the Windows installer from GitHub.
