# eul Published January 1, 2026 · Updated August 10, 2026 macOS status monitoring app Category: System Utilities · Free · Open source · Replaces iStat Menus 7 ($18) · [Official website](https://github.com/gao-sun/eul) ## Install with Homebrew `brew install --cask eul` ## Quick take eul is still a pleasant free system monitor for Mac, but by August 2026 it is no longer the default recommendation, Stats owns the active open-source crown with far more recent shipping velocity. Keep eul if you love its UI and it works on your Mac; otherwise install Stats first. Rating reflects solid core design minus maintenance leadership. Best for: Users who already like eul's SwiftUI UI, Minimal free monitoring without paid iStat Menus, Open-source purists okay with quieter release trains ## What is eul? Complete Guide for Mac Users in 2026 eul is a free, open-source macOS status monitoring app written largely in SwiftUI by developer gao-sun. It puts CPU, memory, network, and battery metrics (plus related sensors) in the menu bar and offers widgets for at-a-glance resource use, a lightweight alternative to opening Activity Monitor for routine checks. **August 2026 status: eul still installs, but Stats is the actively evolving default.** The GitHub project remains public with releases (latest line in the v1.6.x series historically) and Homebrew cask support (`brew install --cask eul`). The Mac App Store build is explicitly noted by the author as **outdated** with some features disabled after SMC-related restrictions. For users on **macOS Tahoe 26.x** and current Apple Silicon machines who want continuous updates, **Stats** by exelban (40k+ GitHub stars, shipping v3.x releases into August 2026) has become the community standard free monitor. eul remains relevant for people who prefer its SwiftUI aesthetic, already rely on it, or want a simpler module set. eul is not discontinued and not acquired. It is a classic open-source utility in a category that moved faster than its release frequency. Competitors include Stats, iStat Menus (paid, deep sensors), Activity Monitor (built-in), and MenuMeters-style tools. Choose eul for minimal free monitoring with open code; choose Stats for the most actively maintained free suite; choose iStat Menus when you need pro-grade sensors and charts. Practically, the decision tree is simple. If you are setting up a new MacBook in August 2026 and want free menu bar graphs for CPU and RAM plus network and sensor readouts, install **Stats** first and live with it for a week. If you specifically prefer eul's layout, or you are restoring a Time Machine migration where eul is already configured, stay. On Apple Silicon under sustained compile or local LLM loads, any menu bar monitor helps you see whether thermal pressure or memory compression is the real culprit before you buy more RAM or close browsers. eul's value was never enterprise support. It was elegant enough monitoring without iStat Menus pricing. That still holds when the app runs; just go in with eyes open about update frequency compared with category leaders. ## Features - **CPU and memory menu bar modules.** Shows load and RAM pressure without opening Activity Monitor. Enough detail to catch runaway Electron apps and browser tab monsters on Apple Silicon Macs before fans spin up. - **Network throughput indicators.** Live upload and download rates help diagnose slow sync clients and unexpected background transfers. Open the dropdown graph when a stall lines up with a backup or cloud client spike. - **Battery information.** Battery status sits in the same menu bar suite as CPU and network, which helps on MacBook laptops when you are chasing drain alongside the system battery indicator. - **SwiftUI interface.** Native-feeling UI built with SwiftUI, including dark mode that matched the Big Sur design language and still looks coherent on modern macOS without the heavy chrome of older monitor apps. - **Desktop widgets.** WidgetKit-style widgets for CPU, memory, network, and battery put metrics on the desktop or Notification Center, not only the menu bar, so you can swipe and check without a permanent icon row. - **Bluetooth battery readouts.** Where supported, peripheral battery levels show up next to system metrics, handy for multi-device desk setups with mice, keyboards, and headphones that die mid-day. - **Open-source distribution.** GitHub releases and a Homebrew cask install without forced accounts. Prefer GitHub over the outdated App Store build if you want the fuller feature set the author still documents there. ## How to Install eul on Mac Install eul with Homebrew or a direct GitHub download. For most people in 2026 the Homebrew cask is the path of least resistance. 1. **Install via Homebrew (Recommended).** The easiest way to install and maintain eul is via Homebrew. Open your Terminal app (Command + Space, type 'Terminal') and paste the following command: `brew install --cask eul`. This handles the download and places the app in your Applications folder automatically. 2. **Launch and Grant Permissions.** Open eul from your Applications folder. On the first launch, macOS may ask for permission to access certain hardware stats. You may simply click 'Open'. Unlike some competitors, eul requires minimal permissions, but ensures you allow it if prompted for network or location (for Wi-Fi SSID) access. 3. **Configure Component Visibility.** Upon launching, you will see a row of new icons in your menu bar. Right-click on any eul item or open the app settings (Preferences) to toggle which components (CPU, Battery, Fan, etc.) you want visible. You can drag and drop them to rearrange the order. 4. **Enable Launch at Login.** To ensure monitoring is always active, go to the eul Preferences menu (cmd + ,), navigate to the General tab, and check the box for 'Launch at login'. This ensures your stats are ready the moment your Mac boots up. ## Pros - Free and open source with a clean SwiftUI presentation. - Menu bar modules cover the metrics most people check daily. - Low friction install via Homebrew or GitHub zip. - Widgets support glanceable monitoring without opening Activity Monitor. - No account, telemetry SaaS, or freemium paywall for core stats. ## Cons - Release frequency and ecosystem momentum lag Stats, which now dominates free monitoring on Mac. - App Store build is outdated relative to GitHub and misses some capabilities. - Sensor depth trails paid tools like iStat Menus for power users and hardware tinkerers. - Future macOS breakage risk is higher when maintenance is quieter than category leaders. ## eul vs Stats in 2026 eul changed how macOS menu bar apps are constructed. Traditionally, these apps were built using Objective-C or AppKit, requiring significant boilerplate to handle UI rendering, especially for dark mode compatibility and high-DPI (Retina) displays. eul bypasses this legacy debt by adopting SwiftUI, Apple's declarative UI framework. The binary stays small and the UI stays responsive. Because SwiftUI uses the GPU for rendering, eul's animations and graphs are fluid without taxing the main CPU thread so the act of monitoring the system doesn't degrade system performance. System monitoring on Mac bifurcated: free open-source tools led by Stats, and paid depth led by iStat Menus. eul occupies a smaller aesthetic niche, SwiftUI polish and simplicity, without matching Stats' release velocity. That is fine for a stable tool that already works, but bundl readers imaging a new Tahoe Mac should default to Stats unless they have a specific reason to pick eul. Always install from GitHub or Homebrew, not the lagging App Store build, if you do choose eul. ## FAQ ### Is eul free? Yes. Fully free and open source with no subscription for core monitoring features. ### Is eul still maintained in 2026? The project remains available with historical v1.6.x releases, but community energy and update frequency favor Stats for new installs. eul is not formally discontinued. ### Should I install eul from the App Store? Prefer GitHub Releases or Homebrew. The author notes the App Store version is outdated and has features disabled. ### eul vs Stats, which is better? For most people in 2026, Stats is the better free default due to active development. Choose eul if you prefer its UI and it meets your needs. ### Does eul support Apple Silicon? Yes, as a native SwiftUI Mac app distributed for modern macOS. Verify on your OS version after major upgrades. ### Can eul replace Activity Monitor? For glanceable CPU/RAM/network checks, yes. For deep process debugging, sampling, and system diagnostics, Activity Monitor or Instruments remain necessary. ### Does eul collect personal data? It is a local open-source monitor. Review the GitHub source if you require formal assurance; there is no SaaS account requirement. ### What are good paid alternatives? iStat Menus is the long-standing paid professional option with richer sensors and charts. ### Will eul slow down my Mac? Any monitor uses some CPU to sample metrics, but well-written menu bar tools are usually negligible compared with browsers and Electron apps. If you see meaningful drain, reduce module count or sampling frequency. ### Can eul show GPU usage? Module coverage is simpler than Stats or iStat Menus. If GPU graphs are mandatory for your workflow, verify eul's current modules or pick Stats/iStat Menus instead. ## Sources - [gao-sun/eul on GitHub](https://github.com/gao-sun/eul) - [eul releases](https://github.com/gao-sun/eul/releases) - [eul on the Mac App Store](https://apps.apple.com/us/app/eul/id1537133867) - [exelban/stats on GitHub](https://github.com/exelban/stats) - [Stats project site](https://mac-stats.com/) - [eul monitoring guide](https://computingforgeeks.com/how-to-monitor-macos-resource-usage-using-eul/) ## Related - [Maccy](https://bundl.run/apps/maccy) - [Stats](https://bundl.run/apps/stats) - [SuperWhisper](https://bundl.run/apps/superwhisper) - [MacWhisper](https://bundl.run/apps/macwhisper) - [HyperWhisper](https://bundl.run/apps/hyperwhisper) - [Aqua Voice](https://bundl.run/apps/aqua-voice) - [eul vs Stats](https://bundl.run/compare/stats-vs-eul) - [eul vs iStats Menus](https://bundl.run/compare/eul-vs-istat-menus) - [Free alternative to iStat Menus 7](https://github.com/gao-sun) ```json { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://bundl.run/#organization", "name": "Bundl.run", "url": "https://bundl.run", "logo": { "@type": "ImageObject", "url": "https://bundl.run/og-image.png", "width": 1200, "height": 630 }, "description": "The Ninite for Mac.
