The disk companion
for Mac, Windows & Linux.

macOS 14 and later today, as a native Swift + SwiftUI app. Windows and Linux are in development as native desktop apps built with Tauri and Svelte, sharing the same local-first promises, the same trash-first safety and the same design language. One disk companion, three platforms.

No — cleanup is one thing it does. DiskAmigo is your computer’s disk companion: it maps every non-removable disk (the startup SSD and any second internal drive) with capacity, free space and usage, surveys each volume folder by folder, reports drive health (SMART, NVMe wear, live read/write), discovers abandoned developer caches (node_modules, Cargo target, Xcode DerivedData), inspects lingering Trash, and uncovers byte-for-byte duplicates. External and network volumes stay opt-in as custom folders.

Yes. Every non-removable, writable volume on your computer is a first-class disk: the sidebar lists them, Disk Usage surveys them and lets you switch between them, drive health follows the disk behind the volume, and the file library, smart filters and duplicates cover them all. Read-only installer or recovery media and removable/network drives are deliberately out — there is no space to manage on media that cannot take a file.

Yes, for the physical disk behind the selected volume. It reads Apple’s own sources — SMART status, media identity and NVMe percentage-used/available-spare, plus live read and write throughput from the IOKit block-driver statistics. All read-only, all local.

DiskAmigo includes a native Model Context Protocol (MCP) server running on a secure local loopback (127.0.0.1:7743) and an stdio bridge. It lets AI assistants like Claude Desktop, Cursor, and Codex inspect disk usage, analyze storage trends, and request cleanups. Every destructive action requires active in-app human approval by default.

Never by default. DiskAmigo operates on a strict trash-first architecture using Apple’s native APIs. Files go to the macOS Trash with Finder “Put Back” support, and ⌘Z instantly restores batches to their exact original locations. Emptying Trash is an explicit opt-in.

Yes. Directories like node_modules, Cargo target/, and Xcode DerivedData are dependency caches and build artifacts. They are easily regenerated with npm install or cargo build whenever you return to a project. DiskAmigo moves them to the Trash so you can always undo with ⌘Z, and your source code is never touched.

Candidate files that match in name or size are grouped instantly. When verifying contents, DiskAmigo hashes candidate pairs using SHA-256 to confirm true byte-for-byte twins with zero false positives. Nothing is deleted automatically — you choose which copy to keep.

The scanner makes a single asynchronous pass over folders with prefetched metadata, so tens of thousands of files are enumerated in well under a second on any modern machine. Memory consumption stays comfortably under 150 MB.

The lifetime price started at $5 for the first 100 licenses and rises in steps — $9, then $15, then $29 — as seats sell. The pricing card shows the price today, how many seats are left at it, and what it goes to next. The count comes from our server, so it is the real number.

A lifetime license for one computer: every feature in the app, every future update, no subscription and no account. Your license key arrives by email within a minute of buying; you activate it in DiskAmigo → Settings → License.

One license covers one computer. If you need more seats for several personal or team computers, write to hello@diskamigo.com.

There is a 30-day refund, no questions asked — simply reply to your receipt email. Checkout and taxes are handled by Polar, so your receipt and refund are proper invoices.

The Mac App Store’s sandbox restricts apps from inspecting system caches, reading developer projects across your home directory, and managing ~/.Trash with ⌘Z undo. DiskAmigo is distributed directly and notarized by Apple so Gatekeeper runs it without warnings.

No file contents, analytics, or telemetry ever leave your computer. Disk surveys, drive-health reads, duplicate hashing and cleanup happen 100% locally on your machine; the only default network check is verifying your license key with Polar.

The MCP server runs exclusively on the local loopback interface (127.0.0.1) with DNS rebinding protection, Host header allowlisting, and per-agent 256-bit Keychain tokens. External web pages or network devices cannot access it.

It is optional and disabled by default. If you choose to enable it, you bring your own OpenRouter API key (BYOK). Only non-content metadata (file names, sizes, extensions, and ages) are sent to score cleanup safety.

That prompt is macOS’s native privacy protection asking permission before an application reads a protected directory like Downloads. DiskAmigo only asks for permissions when needed.
