    Hey HN Ex YC/Google engineer turned indie maker here - excited to share something I just shipped. The System Data in my Mac was taking up 300GB and it took me months to figure out how to clear the old cache, logs, junk and more. And CleanMyMac is a subscription - I refuse to pay subscription fees for Mac apps that run locally. So I built FreeUpMyMac an offline, lifetime Mac cleaner that clear junk with 1 click. And helps you visualize your storage with TreeMap/Sunburst. Hope it’s helpful to you as it is for me. Would love your feedback Tunde

    Instead of a traditional command-style CLI, it runs as a TUI in the terminal, allowing users to inspect cleanup targets before proceeding. On my macOS machines, caches and app data often take up more than 40% of disk usage. Manually cleaning them each time felt tedious, so I built this tool to make the process easier. While similar tools exist, I found it hard to quickly understand how items were categorized or how important each cleanup target was, so I built my own. Repository: https://github.com/2ykwang/mac-cleanup-go Feedback is welcome.

    I do fullstack dev for work and side projects and recently moved everything to a couple VPSs on hetzner. Great setup, low cost, but one thing kept bugging me, how do I know if something is down without manually sshing in all the time? I tried the grafana + prometheus stack but the configuration time and seeing it use more resources than my actual apps was rough. Tried some smaller solutions too but nothing felt right. So I said screw it and built exactly what I wanted. tori is a single go binary that runs on your server, reads host metrics from /proc and /sys, monitors containers…
