CoreTidy

Closed-source macOS dev-junk cleaner that exists only as a waitlist landing page (nothing shipped as of 2026-10-31): native Swift app using on-device Core ML to flag 'safe to delete' items - dead node_modules, Xcode DerivedData/caches, iOS DeviceSupport, simulator runtimes, abandoned project folders - grouped 'Safely Rebuildable' vs 'Needs Review' with a per-item reason. Stated guardrails: Trash-only deletes, App Sandbox, AI advisory-only behind an explicit Clean click, '0 bytes uploaded', works offline. Pay-once $39 lifetime license, $19 for waitlist joiners.

Sandboxed, Trash-only, on-device and no-telemetry are landing-page and comment promises for software that has not shipped - nothing exists to verify them against.

Research notes

Waitlist-stage entry: no build, no repo, no release date - the site is a Next.js page collecting emails against what the launch post calls 'the concept'.
Stated safety model (author comments in the launch threads): never auto-deletes, moves items to macOS Trash only, sandboxed and restricted to user space, Core ML strictly advisory behind an explicit 'Clean' click, every suggestion carries a reason.
Docker claim walked back same-day: a commenter pointed out Docker Desktop keeps images inside one Docker.raw disk image and the App Sandbox blocks the daemon socket; the author removed 'Docker images' from the landing page within hours, though the launch selftext still lists them.
Pricing anchors against Apple's $200 storage upgrade ($39 lifetime / $19 waitlist); the dollar figure was added next to the email field same-day after a commenter noted '50% off' anchors to nothing.
First r/MacOS submission (2026-10-30) removed by a moderator; reposted 2026-10-31 inside the sub's 'Developer Saturday' window.

Oct 30, 2026 r/MacOS — [ Removed by moderator ] by u/hoodati (archived copy)removed

Earliest promotion found (arctic author-post listing; original title not captured - reddit overwrote it on removal). Link post to coretidy.vercel.app submitted Fri 2026-10-30 16:34 UTC; r/MacOS restricts dev posts to 'Developer Saturday', the likely reason for removal and for the next-day repost.

Oct 31, 2026 r/MacOS — Tired of the "Apple Tax" for storage, so I'm building a smart local disk cleaner. Looking for harsh feedback. by u/hoodati

Earliest live promotion (link post to coretidy.vercel.app with body text), posted inside r/MacOS 'Developer Saturday' after the Oct 30 submission was removed by a moderator. Author discussed the safety model and pricing in the comments.

Apple charging $200 for a 256GB storage bump is ridiculous. I'm constantly maxing out my base model Mac, and honestly, the existing disk cleaners kind of suck. They're mostly overpriced subscriptions running in the background, or they just hand you a massive pie chart and expect you to manually dig through folders yourself. — Problem statement

I got fed up and started building my own native tool, CoreTidy. Instead of just listing big files, it uses local Core ML to figure out what's actually safe to delete. It specifically targets dev junk like dead node_modules, leftover Docker images, massive Xcode caches, or old project files sitting untouched for months. — Tech bingo

My strict rule for this: everything happens locally on Apple Silicon. Not a single file name or piece of metadata leaves the machine, because cloud APIs for disk scanning are a privacy nightmare. Plus, no subscriptions. It'll be a flat one-time fee. — Trust signal

I'm open to feedback, feel free to reach out to me personally or here — Engagement hook
