Open source alternative to Cork and CleanMyMac
Last verified
Manage and install over 5,000 Homebrew apps on Mac with a visual app store, pre-install malware scanning via ClamAV, and system monitoring.
Browse and install over 5,000 casks with screenshots, rankings, and release notes. Daily update checks handle Homebrew, App Store, and other update mechanisms in one place, so the morning routine is a click rather than a sequence of brew commands.
You are comfortable with brew in Terminal and already have an update workflow. OpenNavo adds the most value for users who have Homebrew installed but rarely open Terminal.
Add apps to a Brewfile list while browsing opennavo.com. On a new Mac, running brew bundle with the exported file installs every app in the list. Collections can also be exported directly as a Brewfile.
Your team already manages Mac provisioning with tools like Ansible or MDM. Brewfile export is most useful for personal or small-team setups.
The uninstaller finds the data, caches, preferences, and background items left by an app across all three install sources (Homebrew, App Store, and disk image installs). The cleanup scan sorts leftovers into risk tiers before anything is deleted, with files going to Trash by default.
You need commercial support or guaranteed safe deletion with rollback beyond Trash. CleanMyMac and similar tools have longer track records and customer support channels.
ClamAV scans run before every Homebrew install and on every file that lands in Downloads. Startup items are catalogued and new additions trigger an alert immediately. System check shows the status of SIP, Gatekeeper, FileVault, XProtect, and the firewall in one screen.
You need enterprise-grade endpoint security. ClamAV has limited coverage of Mac-specific malware compared to dedicated macOS security products. OpenNavo adds to macOS built-in protections but does not replace a dedicated endpoint security tool.
Homebrew is one of the most reliable ways to install software on a Mac, but its command-line interface puts a ceiling on who can use it. Remembering exact cask names, running brew outdated to find stale apps, and looking up changelogs separately are friction points that push many Mac users back to the App Store or scattered download pages. There is no built-in way to browse what is available, compare options, or know what changed in a new version.
For Mac users who also want to keep their system clean and secure, the problem multiplies. Dedicated cleanup tools like CleanMyMac run as proprietary software and require paid subscriptions, meaning you cannot inspect what they delete or how they determine what is safe to remove. Malware scanning on Mac is either limited to built-in XProtect or requires a separate paid product. Having separate paid tools for Homebrew management, malware scanning, cleanup, and system monitoring adds up quickly.
Over 5,000 Homebrew casks organized with descriptions, screenshots, installation counts, dependencies, and per-version release notes. Rankings follow real install data from the past 30 days. The web directory at opennavo.com lets you browse and copy brew commands without installing the app.
The macOS app queues tasks with live Homebrew command output, so you see exactly what runs. Daily update checks cover Homebrew, the App Store, Sparkle, Electron, and GitHub releases. Apps can be pinned or skipped; running apps prompt before an update proceeds.
Every download goes through ClamAV before it installs. New files in Downloads are scanned automatically. Scheduled quick scans cover the Desktop and startup items; full scans cover the whole Mac. Scans run locally and no files are uploaded to any server.
Twenty categories of startup items are tracked, from background services and login items to browser extensions, each with its owning app and signature. New startup items trigger an alert. Signature checks catch apps whose developer certificate changed after install.
Uninstalls apps from Homebrew, the App Store, or disk images and finds associated data, caches, preferences, and background items before removing anything. A read-only scan categorizes leftovers into risk tiers; caches are deleted directly, while other files go to Trash so the action can be undone.
CPU, GPU, memory, disk, network, battery, temperatures, and fans are available as menu bar items, shown as text or small charts. SMART drive health, per-process resource usage, and fan speed control are included. Readings stay in memory and are never written to disk or uploaded.
Cork is a paid Homebrew GUI for macOS. Both Cork and OpenNavo give Homebrew a visual interface for installing and updating casks without Terminal.
| Feature | OpenNavo | Cork |
|---|---|---|
| License | GPL-3.0 | Proprietary |
| Price | Free | Paid |
| Malware scanning | ClamAV, pre-install | None |
| System monitoring | CPU, GPU, memory, fans | None |
| Mac cleanup | Yes, with leftovers detection | None |
| App Store updates | Yes | No |
OpenNavo is the better choice when you want Homebrew management alongside malware scanning, cleanup, and system monitoring in one free tool. Cork may be a better fit if you want a narrower app focused purely on Homebrew management and do not need the security and monitoring features OpenNavo includes.
CleanMyMac is a subscription-based Mac optimization suite from MacPaw that covers cleanup, malware scanning, and system monitoring. The two tools overlap in cleanup and monitoring, but OpenNavo adds Homebrew management while CleanMyMac does not.
| Feature | OpenNavo | CleanMyMac |
|---|---|---|
| License | GPL-3.0 | Proprietary |
| Price | Free | Paid subscription |
| Homebrew management | Yes, full GUI | No |
| Malware scanning | ClamAV | Proprietary engine |
| Mac cleanup | Yes, risk-tiered | Yes |
| System monitoring | Yes, with fan control | Yes |
OpenNavo is the better choice for Mac users who want cleanup, monitoring, and malware scanning at no cost and want to inspect the source code behind what runs on their system. CleanMyMac's proprietary malware engine has broader Mac-specific threat coverage and comes with MacPaw customer support, which matters for less technical users who want a supported product and do not want to manage an open source tool.
Download the signed macOS app from GitHub Releases: https://github.com/opennavo/OpenNavo/releases/latestYes. OpenNavo is free to download and use with no paid tier or subscription. The source code is published under GPL-3.0 on GitHub.
No. OpenNavo wraps Homebrew, so Homebrew must already be installed on your Mac. The app calls brew on your local Homebrew installation and does not ship its own version. The server never runs brew itself: installation and updates run on your Mac only.
OpenNavo ships the open-source ClamAV engine with its virus database updated from ClamAV's official servers. Downloads are scanned after Homebrew finishes downloading and before the cask installs. New files in your Downloads folder are also scanned automatically. Scans run on your Mac and no files are uploaded. ClamAV's coverage of Mac-specific malware is limited, so OpenNavo also checks signatures, notarization, and startup items alongside ClamAV.
Yes. OpenNavo requires macOS 13 or later and supports both Apple silicon and Intel Macs.
Yes. You can add apps to a Brewfile list while browsing and export it in one click. On a new Mac, running brew bundle with the exported file installs every app in the list. Collections can also be exported directly as a Brewfile.
