Coding agents work fast and leave a lot behind: a worktree for every parallel task, a scratch folder for every session, a fresh node_modules for every build. A general cleaner like CleanMyMac sees those as folders. Devbroom sees which agent made each one, whether a session is still running in it, and whether it holds work you haven't saved. That's the difference that matters when the folder is someone's afternoon of work.
Built for the folders agents leave
Devbroom knows where your agents keep their sessions, scratch folders and caches, and follows each agent's own rules: what the agent cleans by itself is left to the agent, what has its own command is left to that command, and your accounts and settings are never touched. It finds git worktrees even outside your project folders, build folders like node_modules, target and .venv, and developer caches such as npm, pnpm, Cargo and Xcode DerivedData.
CleanMyMac is a broad Mac maintenance app with more than 25 tools. Since July 2026 MacPaw also offers CleanMyMac CLI, a separate terminal tool in public beta: clean dev covers developer caches from Homebrew and npm to Docker and JetBrains, purge finds project build folders by name, and clean ai covers junk from AI tools; MacPaw names Claude Code and Codex. Its docs don't mention git worktrees, running agent sessions or undo.
Safe by evidence, not by promise
CleanMyMac relies on a safety database of rules for each macOS version and app, and asks you to quit some apps before it cleans their caches. Its Large & Old Files tool deletes permanently, bypassing the Trash. Devbroom shows you the evidence for each item and lets you decide:
- A worktree with uncommitted changes is Blocked. Devbroom never uses
git worktree remove --force. - If an agent session runs in a folder, a process runs from it or a file in it is held open, the item is Blocked.
node_modulesis Ready only with apackage.jsonbeside it; a name alone is never enough.- When you press Clean, every item is checked again. Cleaning moves items to the Trash, and you can put each one back from History.
Every rule is on the Rules page, and none of them is a setting you could switch off by accident.
Your agents can ask, you decide
Devbroom comes with an MCP server, so Claude Code, Codex or Cursor can ask whether a folder is safe to delete before they touch it, or request a cleanup that comes to you for approval. There's also the devbroom command and a menu bar panel. See Integrations.
Pay once, or not at all
Scanning, verdicts, cleaning, History, the command line and MCP are free. Pro is a one-time $29 for 2 Macs, with a year of updates, and adds Automatic upkeep, Analytics and the session tools. No subscription. CleanMyMac starts at $39.95 a year ($3.33 a month) for one Mac; MacPaw also sells a one-time license from $119.95 that covers the current major version, and it's on Setapp. Details on the Pricing page.

When CleanMyMac is enough
If you don't use coding agents and want one app for the whole Mac, with malware scanning and an app uninstaller, CleanMyMac covers that. The two don't get in each other's way: plenty of developers keep a general cleaner and use Devbroom for the folders their agents fill.
