Baa：一款释放 AI 智能体遗忘内存的菜单栏应用
Show HN: Baa – a menu bar app that frees RAM your AI agents forgot about
Baa 是一款 macOS 14+ 菜单栏应用，可识别 AI 智能体启动后闲置 15 分钟以上的进程、未关闭的应用脚本及闲置的 Ollama 模型等内存占用，显示可回收的 RAM 并支持一键释放。它同时监控内存压力（绿/黄/红），并清理旧构建和包缓存等磁盘垃圾，提供 `baa free`、`baa disk` 等终端命令，且不会自行终止任何进程。
a tiny ram for your RAM
tldr; baa lives in your menu bar, tells you when your mac is about to run out of RAM or disk, finds the stuff quietly eating it, and frees it in one click.
why
i built this because my mac keeps running out of RAM every 2 hours and i typically get around it by closing random apps and hoping it will help (it usually doesn't).
baa 🐏 is a little ram that headbutts all of that out of your mac.
what it does
- lives in your menu bar as 🐏 + how much RAM is free. turns 🟡 / 🟠 / 🔴 when things are getting tight
- finds stuff you forgot was still running:
- 👻 apps and scripts that should've closed but didn't
- 🤖 things ai agents started and forgot about
- 💤 big stuff just sitting there idle (agent sessions idle for hours, docker with no containers, an ollama model still loaded)
- tells you how much RAM you'd get back, and frees it in one click
- pings you a few minutes before you run out
- also finds dev junk filling up your disk (old builds, package caches etc.) and trashes it in one click
- plays a tiny baa when it frees something 🐑 (you can mute it but it's the best part imo)
install
you'll need macOS 14+ and xcode command line tools (xcode-select --install).
git clone https://github.com/selviarora/baa && cd baa ./install.sh
that builds the app into ~/Applications, starts it when you log in, and adds the baa command.
commands
baa |
RAM readout + leftovers, right in your terminal |
baa free <id> |
free one leftover (ids are in the readout) |
baa free all |
free everything it found |
baa disk |
dev junk taking up your disk |
baa disk clean <id> |
clear one (or all) |
baa test |
send a sample notification |
how it decides what's a leftover
basically baa looks for stuff that's still running but not doing anything:
- its app or terminal is closed but it's still going
- an ai agent started it and it's been sitting idle for 15+ min
- it's big and hasn't used any cpu in a while
it also watches memory pressure (the green / yellow / red graph in activity monitor), not just how much RAM is used. macs use most of their RAM all the time and that's usually ok!
it will also never kill anything on its own.
uninstall
launchctl bootout gui/$(id -u)/com.selvi.baa rm -rf ~/Applications/Baa.app ~/Library/LaunchAgents/com.selvi.baa.plist ~/.local/bin/baa
vibecoded this in 30 mins so hopefully nothing is broken!
