Homelab Diagnostic CLI & AI Fixer
A downloadable CLI tool that analyzes a user's docker-compose file, checks the host's mount points (detecting exFAT/NTFS), and verifies UID/GID permissions. It outputs the exact commands needed to fix permission errors or generates a corrected fstab/compose file.

Community Voices
Real quotes from Reddit comments that inspired this opportunity
- “having trouble with the PUID and GUID”
- “the folder is not writeable by user abc”
- “UID and GID are vital to know if dealing with docker and filesystems. Kinda sucks because it's not easy to get”
- “ExFAT is causing problems here. You can’t chown or chmod on ExFat.”
- “Your real problem is almost certainly the external SSD's filesystem. If it's formatted exfat or ntfs, chown and chmod don't behave the way you expect”
- “I formatted my SSD from NTFS to ExFat and mounted using root but still could not get it working.”
