- Repo deleted (now 404); it carried a custom noncommercial license anyway. Launch post advertised a notarized build
Relations
- inspired by DiskBuddy
DiskBuddy has inspired the project. This was initially sold at $12, and users complained about memory leaks, permission issues, and app blocks when you run Duplicate File Finder.
Research notes
- False open-source claim: launch posts say "open-source, MIT licensed" but the archived repo LICENSE was a custom noncommercial "License 1.0.0" (commercial use requires a separate license), and the repo has since been deleted (404).
- Removed r/MacOS post claimed "Free on Github!" in its title; no public repo exists.
- Sockpuppet pattern: two reddit accounts (u/lazykid07, u/introvertmac) post near-identical launch bodies and both claim "I built SpareDisk"; introvertmac also promotes the same minilabs.cc portfolio (Paydesk) and asks r/AskReddit "what is your review of minilabsDOTcc mac tools?".
- GitHub identity 0xdevrel is mostly web3/AI projects; App Store seller is "Manish Bhattacharya".

Sep 12, 2026 r/macapps — [OS] SpareDisk: Free Disk Space. Open Source with Pay whatever you want for Notarized app by u/introvertmac
Earliest announcement found; links github.com/0xdevrel/sparedisk (repo later deleted)
I built SpareDisk over the last few days, kept it bare minimum in terms of bloat features but focused on speed, parallelism, and queue management. — Intro cliche
I saw lots of Disk Space Cleaner with > $10 price, which are basically a good interface for your Mac native storage. — Problem statement
The code is open source, and if you can compile it: use it for free, you can customize your design and stuff. — Virtue
No account. No uploads. Your files stay on your Mac. — Trust signal
SpareDisk is App Store friendly(App is pending for review). It is sandboxed, following Apple’s permission guidelines and memory optimisation. — Trust signal
I would really appreciate a star on the GitHub repo! — Engagement hook
Sep 20, 2026 r/freesoftware — SpareDisk 1.2: Claim your free space back on Mac by u/lazykid07
Later promotion by the second account (u/lazykid07); still claims open-source/MIT as the app pivoted to paid - kept for the sockpuppet and pivot evidence.
The code is open-source, MIT licensed: if you can compile, you can use it for free :) — Virtue
