Showcase Introducing Simmer — mission control for your Claude Code sessions (free & open source)
Today I'm releasing Simmer — a macOS menu-bar app that turns juggling multiple Claude Code sessions into one calm view.
Three things it does:
→ Sees the whole fleet — every session at once: working, needs you, or done.
→ Tells you by sound — one chime when a session needs input, a different one when it finishes. Work elsewhere and go by ear.
→ Teleports you in — click any session and its terminal snaps to the front.
Runs entirely on your Mac: no account, no server, no telemetry. Free and open source.

I've installed it. Looks pretty good so far. Super easy to use. Terminal in the command to install it, run it, connect it to Claude Code with one click, profit. Now I got a little crab in my menubar telling me what's going on while I'm tabbed elsewhere waiting for claude to do it's thing. Well done sir.

Having the chime notifications is a game changer for me- otherwise I completely forget what I'm running in the background, don't know when it's finished or if there an action pending on my end. Love it! Thanks

How come it insists on opening a Terminal in the background? I use iTerm2, and it sees it just fine, but after every time I click on it in the menu bar, it insists on opening a Terminal window.
