What is Yardlet?

Yardlet is a native Mac app built with Swift and SwiftUI that runs coding agent CLIs such as Codex, Claude Code and OpenCode side by side in one window. It starts each agent's own CLI with its existing sign-in and keeps sessions in the agent's own store. A task started in Yardlet can also resume in the Codex app, and Yardlet writes nothing into the agents' configuration.

Agents can read, message or hand work to each other. Account limits remain visible, and a connector set up once serves every agent. The built-in browser plays H.264 video and lets agents fill saved sign-ins without seeing passwords. Diffs and pull request checks sit next to the conversation.

Yardlet is free and MIT licensed, for macOS 15 or later on Apple silicon.
