Your Mac Is Secretly Hoarding 50GB of Junk — Someone’s Cashing In on This Pain

Tuesday afternoon, a tool called DevCleaner launched on Product Hunt. 111 upvotes, 18 comments — not a blowout, but the comment section had a consistent vibe. Not "cool" or "nice," but "finally someone made this" and "I cleaned up my Cursor cache and freed 12GB instantly."

This is a signal everyone’s ignoring.

Slug: devcleaner-mac-dev-tools-cleanup-opportunity

I Spotted a Signal

DevCleaner does one simple thing: scans your Mac for cache, logs, and temp files left behind by dev tools and AI apps, then cleans them in one click.

Not Deep Clean, not CleanMyMac — it’s specifically for dev tools and AI apps — Node’s node_modules leftovers, Docker’s dangling images, Xcode’s DerivedData, Cursor’s .cursor cache, Chrome’s DevTools logs…

I read through all 18 comments. No one asked, "Is this safe?" What they asked was: "Can it clean Claude Code’s cache?" "Does it support Windsurf?" "Can it also scan Docker’s build cache?"

That’s a massive signal.

Why? Because when a product launches and users’ first reaction isn’t questioning its value but demanding support for more of their own tools — that means the pain point already exists, just without a good solution.

In Plain English

Your Mac is getting slower, but it’s not because the hardware is aging.

How many dev tools have you installed in the past two years? VS Code, Cursor, Windsurf, Claude Code, Docker, Figma, Chrome, Node, Python virtual environments… Every single one leaves behind cache, logs, temp files, and build artifacts.

Cursor’s AI model cache can eat 2-5GB per project. Docker’s dangling images, if you frequently pull new ones, can stack up to 10GB+ in months. Chrome’s DevTools logs, if you’re a heavy frontend dev, can generate hundreds of MB per day.

Most developers know these files exist, but they don’t know the total size — and even less about which ones are safe to delete.

DevCleaner’s smart move: it doesn’t claim to be a "Mac cleaning master." It does one thing — lets developers see how much space their tools are eating, then gives it back in one click.

Who’s Hurting? Why Now?

Who’s hurting: Indie developers, freelancers, and small startup teams using Macs. Especially those with 256GB/512GB drives. I know a guy building AI apps — 512GB MacBook Pro, six months later only 30GB free. He spent an afternoon manually cleaning and accidentally deleted an important Docker volume.

Why now: Three reasons —

1. AI tools exploded. Cursor, Claude Code, Windsurf, GitHub Copilot… These tools eat way more space than traditional IDEs. AI model cache, session history, code indexing — each can consume gigabytes.
2. Upgrading storage got harder. Apple Silicon Macs have soldered SSDs — you can’t add your own. 512GB is 512GB. When it’s full, you buy a new machine.
3. Developers fear "cleaning." Manually deleting stuff in ~/Library/Caches requires knowing what you’re doing. Most people won’t touch it.

Pricing Anchor

DevCleaner is currently selling on Product Hunt for $12 one-time purchase (limited-time discount). This pricing is clever:

• $12 < the mental cost of a bubble tea. For a developer, spending $12 to solve a six-month pain point is a no-brainer.
• One-time vs subscription. Cleaning tools follow a "use once, solve it" logic — subscriptions actually scare people off.
• Compared to competitors: CleanMyMac X costs $39.95/year and does way too many non-dev things. DevCleaner focuses only on dev scenarios at 1/3 the price.

There’s an Opportunity Hiding Here

DevCleaner’s direction is right, but it’s still too early.

Right now it only scans and cleans. But what developers really need isn’t "cleaning" — it’s "management."

Let me sketch a product roadmap. If the DevCleaner team doesn’t build it, you can:

Opportunity Description: Developer Disk Space Management Platform

Not a "cleaning tool" — a "health dashboard for developer tools."

It does three things:

1. Visualization: A Mac menu bar widget showing real-time disk usage per dev tool. Cursor: 12GB, Docker: 8GB, Xcode: 15GB… see it at a glance.
2. Safe Cleaning: Auto-identifies files safe to delete (AI cache, build artifacts, logs) vs files to never touch (config files, auth credentials). Safety is priority one.
3. Continuous Monitoring: Set thresholds — auto-clean Docker dangling images when they exceed 5GB, alert you when Cursor cache hits 10GB.

Who Pays? How Much?

First payers: Indie developers + freelancers, using Mac, drive ≤ 512GB, daily use of 3+ dev tools.

Pricing:

• Lite (Free): Scan + report showing how much space is eaten
• Pro ($19 one-time): One-click clean + safety rules + weekly auto-scan
• Team ($9/month/seat): Team disk usage reports + compliance cleaning policies + Slack notifications

Why Most People Will Miss It

The mainstream view: "What’s there to do with a cleaning tool? CleanMyMac already does it, CCleaner already does it."

Wrong. Here’s why:

1. Generic cleaning tools aren’t dev-friendly. CleanMyMac might suggest cleaning Docker containers, but it can’t tell which ones are in use vs abandoned. Developers won’t trust it.
2. Dev tool disk consumption is accelerating. In 2024, Cursor user growth hit 300%+. Claude Code grew 400%+ in Q1 2026. Every new tool brings new caching strategies. This is a dynamic problem, not static.
3. One-time purchase + vertical niche = low decision cost. $12 one-time vs $39/year subscription — for "occasional use" scenarios, one-time wins.

Evidence: Of DevCleaner’s 18 comments on Product Hunt, zero are negative. That’s extremely rare on PH. Typically, a new tool gets at least 20% comments like "I can do this with X" or "What’s the point?" DevCleaner didn’t. Because the pain is too real.

Why Most People Will Miss It

Let me be direct: Most builders look down on the cleaning tool space.

They think:

• "Isn’t this just a sub-feature of CleanMyMac?"
• "Developers can clean themselves — no need to pay."
• "The market’s too small, not worth it."

Every single judgment is wrong. Let me break it down:

"Isn’t this just a sub-feature of CleanMyMac?" CleanMyMac scans "Mac general junk." It doesn’t know what ~/.cursor/cache is, doesn’t know what ~/Library/Application Support/Claude Code/ stores, doesn’t know the difference between Docker’s build cache and image cache. Developers need a cleaning tool that understands dev tools.

"Developers can clean themselves — no need to pay." In theory, yes. But in reality, 8 out of 10 developers I know have never cleaned their dev tool cache. Not because they don’t want to — because they don’t know what’s safe to delete and what isn’t. The risk of manual cleaning is too high — delete the wrong Docker volume and your entire database is gone. Spending $12 on a safe one-click clean is way better than spending an afternoon manually cleaning and then worrying.

"The market’s too small." There are 27 million developers globally. Assume 30% use Mac — that’s 8 million. Assume 20% have disk space anxiety — that’s 1.6 million. $12 x 1.6 million = $19.2 million. That’s not even counting Team subscription revenue. Small market?

If It Were Me, Here’s What I’d Do

I’d break this opportunity into three validation steps — all completed within 7 days.

Day 1 (2 Hours to Build)

Don’t build the product. Build a page.

A simple landing page:

• Headline: "How much space are your Mac dev tools eating?"
• Subheadline: "Free scan, 5-second report."
• One button: "Download Free Scanner"
• Promise: Won’t delete any files — just generates a report

The tool itself: A simple Swift script that scans common dev tool cache directories, calculates total size, and outputs an HTML report. Wrap it in a SwiftUI Mac menu bar app. 2 hours is enough.

Why scan first, not clean? Because scanning is zero-risk — users are willing to try it. The scan report itself is an "aha moment" — when users see Cursor eating 12GB, their purchase intent skyrockets.

Day 2

Ship the scanner to Product Hunt with the title: "DevScanner: Free Tool to See How Much Space Your Dev Tools Are Eating"

Pricing strategy: Scan is free, cleaning feature is $9 one-time.

Goal: See how many people download, and how many click the "Clean" button from the scan report page.

Day 3-7

Collect scan data from the first 100 users. Analyze:

• Which tool eats the most space? (Likely Docker or Xcode)
• Average reclaimable space per Mac (in GB)?
• What are users’ most common questions?

Based on data, decide whether to build the cleaning feature.

Validation criteria:

• 100 scan downloads → Continue
• 30% of users click "Clean" → Build cleaning feature
• 10% of users willing to pay → Start building seriously

MVP Plan

No fancy UI needed. A Mac menu bar app + a simple SwiftUI interface + a cleaning script. No backend needed — reports are generated locally, cleaning runs locally.

Tech stack:

• Swift + SwiftUI (native Mac app)
• Local filesystem scanning
• Safe cleaning rules (whitelist mode: only delete clearly safe file types)

Pricing Plan

• Free: Scan + report + manual cleaning guide (tells users which files they can manually delete)
• Pro ($12 one-time): One-click smart cleaning + weekly auto-scan + cleaning history

Failure Conditions

When is this judgment wrong?

1. Developers genuinely don’t care about disk space. If the scan report shows average reclaimable space < 5GB, the pain isn’t sharp enough. But if it’s > 20GB, it’s worth doing.
2. macOS’s built-in storage management is already good enough. macOS’s "Storage Management" can clean some cache, but it doesn’t understand dev tools. If you find developers already comfortable with system tools, the pain is solved.
3. Competitors move fast. If CleanMyMac launches a "Developer Mode," or Cursor starts auto-cleaning its own cache, this market gets eaten. But given big company response times, you have a 3-6 month window.
