Building with AI agents means many dev slots at once, each with its own Docker environment, node_modules and build data. Sluice lives in your menu bar, knows where Xcode, Docker, Rust, Go and npm hide leftovers, and frees them safely. Never during a build.

Hi Product Hunt, I'm Rachid.

I built Sluice for myself. My Mac runs a lot of work in parallel these days: AI agents in up to 20 dev slots, each in its own worktree with its own isolated Docker environment, its own DerivedData and its own caches. It's a great way to build, but my disk was full every single day. Builds failed halfway with "No@ space left on device", and I lost time digging through ~/Library to find what I could safely delete.

So I wrote a small menu bar app that knows where Xcode, simulators, Docker, Rust, Go, Gradle and EAS hide their leftovers, finds the node_modules, target and .venv folders in your projects, and only removes what comes back by itself. The one rule: never break someone's work. It won't touch anything while a build runs, and it never goes near your code, your data or your Docker volumes.

The results impressed me: the first afternoon I ran it, it freed 61 GB on my Mac. So I decided to release it.

Sluice is free: download it and clean with one click. Pro is on the way: it cleans every night and whenever space runs low, adds your own folders with keep-the-newest rules, and gives you sluice clean for scripts and agents. I'll price it so that it's not worth rebuilding yourself, even with AI.

I'd love to hear which tool eats your disk. If Sluice doesn't know it yet, I'll add it.

@rachid_al_maach I run into this problem with Xcode. I have to limit concurrent simulators, etc.

Knowing where Xcode and Docker hide their leftovers and refusing to clean during a build is exactly the safety I would want before letting something delete files on my machine.
