Mac app to manage multiple programming agents side by side
Yardlet is a Mac app for people who already use programming agents. It does not provide a model itself, but receives your installed command line agents such as Codex, Claude Code, and OpenCode into an interface and runs them side by side, each retaining its original login status and session records.
All agents share a sidebar, an input box and a set of approval cards. When an agent wants to perform a dangerous operation, it will tell you in plain English what it wants to do, and it is up to you to decide whether to let it go or not. The modified code can be reviewed first and then merged just like PR review. It can also display the quota usage of each account, has a browser for agents, and also supports remote viewing and operation from mobile phones.
Free and open source, MIT license. It is suitable for developers who have subscribed to several programming tools at the same time and want to schedule them uniformly in one place.
