A native Mac app that maps your whole disk in seconds and finds what you can safely remove, with a focus on developer and AI clutter: Xcode and simulators, node_modules, package caches, Docker, local AI models and agent worktrees.
24.1 GB is safe to clean — Xcode DerivedData, node_modules and caches. Move them to the Trash?
Bytewell includes an MCP server. Connect your assistant with one click from the app, then just ask.
What's filling my disk? Clean what's safe.

24.1 GB is safe to clean — Xcode DerivedData, node_modules and caches. Move these 14 items to the Trash?
Yes, go ahead.

Done — 24.1 GB is in the Trash. Want me to put anything back?
.env files and iCloud are always refused.Safe items rebuild themselves. Review items are your data or a long re-download. Anything a tool manages better, like an Ollama model or a simulator runtime, comes with the exact command instead.
Rings, blocks or a 3D city of your folders, and what changed since the last scan.
Build output and dependencies per repo, with stale projects flagged.
Ollama, LM Studio and Hugging Face side by side, with weights you stored twice.
What Docker really keeps, and what hides in macOS's grey “System Data”.
docker system prune -a
The big files from a scan, or any folder down to 1 MB. Compared in full before anything moves; APFS clones are recognised, so shared space is never counted twice.
Used space over time, folders that keep growing, and the date you'd run out at this pace.
Free space in the menu bar. Scheduled scans notify you only when something is worth doing.
Pick an app you no longer use: its caches, settings, saved windows and login items go with it, in one step you can undo. Bytewell also finds what already-removed apps left in your Library.
Bytewell follows the language you choose for it in macOS.
Disk cleaners earned a reputation for being aggressive. Bytewell starts from the other end: when it isn't sure, things stay where they are. Every promise comes with the rule that keeps it.
Bytewell has no delete function at all. Everything moves to the Trash, and only you can empty it — not Autopilot, not an AI agent.
Undo puts each item back exactly where it was, after checking it's the very same item and not something that took its name.
Right before anything moves, it's checked on disk again. If it changed since the scan, it stays.
Keychains, Mail, Messages, Photos, iCloud Drive, browser profiles, password managers, SSH keys and .env files are always refused.
Removing an app takes only what is certainly its own. Anything that may hold your documents stays unless you tick it.
An agent sees a preview, needs your OK to move anything, and has exactly your limits — it can't delete either.
No account, no analytics. Scans read sizes and dates, never what's inside your files.

No, never. Bytewell has no permanent delete. It only moves items to the Trash after you confirm (or after an AI agent shows you a preview and you agree), every move can be undone, and only you can empty the Trash. Autopilot, if you turn it on, only moves old, safe caches that rebuild themselves — to the Trash as well.
Yes. Pro's Apps page removes an app together with the caches, settings and login items it keeps in your Library — to the Trash, in one step you can undo. Anything that may hold your own documents stays unless you tick it, and parts of macOS are never offered. It also finds leftovers of apps you already removed.
English, German, Simplified Chinese, Japanese and Turkish. Bytewell follows your Mac's language; to pick another one just for Bytewell, use System Settings › General › Language & Region › Applications.
No. Scans, history and your license are stored on your Mac, and the license is checked offline. With Pro, Bytewell downloads a public list of cancelled keys about once a week, and once a day it checks for updates (sending only the app and macOS version numbers). No analytics, no account.
Bytewell checks for updates once a day and shows a small red badge when a new version is out — no pop-ups. Every update is signed by Axleno and verified on your Mac first. Updates are free for life.
To measure folders macOS protects (Mail, Safari and other apps' data) so the totals are complete. It works without it too, with those folders counted as unreadable.
You pay once and keep Pro, including every future update, on all of your Macs. $19.99 is the launch price.
Yes, within 30 days — see the refund policy.
Any Mac with Apple silicon or Intel running macOS 15 Sequoia or later.
